Permeabilidade e variação do albedo de pavimentos frios em função do teor de umidade
Authors: Kowalski Luiz Fernando , Da Silva Taís Maria , Silva Vitor Hudson Nascimento , Ríspoli Italo Alberto Gatica , Masiero Érico
Published: October 2022

Os pavimentos frios, com maior capacidade drenante, podem contribuir no controle de enchentes e na temperatura das cidades. Sendo assim, este trabalho tem por objetivo relacionar o coeficiente de permeabilidade à variação do albedo de pavimentos frios em função do teor de umidade. Essa pesquisa é de caráter experimental e inicia-se com a determinação do coeficiente de permeabilidade de pavimentos de concreto permeável e semi-permeável. Em seguida, é avaliada a variação do albedo em função do teor de umidade das amostras na coloração cinza e grafite. Como resultado, percebe-se que para a mesma coloração, cada tipo de pavimento (permeável e semi-permeável) apresenta valores diferentes de albedo.  O pavimento semi-permeável na coloração cinza possui um albedo 20,6% superior em relação à placa permeável de mesma cor. Isso acontece em todas as condições de ensaio, estando os materiais secos ou saturados.
Miguel Juliano, Bramante Buffoni e uma residência modernista em Ponta Grossa/PR
Authors: Sgarbossa Gabriela Kratsch
Published: October 2022

O presente trabalho tem como objetivo analisar a presença da obra de arte na composição arquitetônica modernista, por meio de um estudo de caso em uma edificação residencial de porte médio, localizada em uma cidade no interior do Paraná. Para tanto, foram utilizados métodos exploratórios e analíticos, em fontes bibliográficas e documentais, assim como realização de pesquisa de campo para analisar a obra in loco. A obra escolhida foi a residência Therézio Xavier, projetada por Miguel Juliano e que possui um mural vidroso do artista ítalo-brasileiro Bramante Buffoni. Os principais resultados atingidos indicaram que a síntese das obras, desejada pelos arquitetos modernistas, conseguiu influenciar grande parte da arquitetura que se desenvolve após a construção do edifício-sede do então Ministério de Educação e Saúde, atingindo inclusive edificações de caráter residencial no interior do país, embora não se consiga dimensionar sua atuação enquanto função educacional. Acerca da obra estudada, percebeu-se que esta detém grande influência na paisagem local, bem como características muito aproximadas às outras obras em suportes equivalentes desenvolvidas por Buffoni na capital paulista.

Development of the algorithm of the orbital space telescope orientation and stabilization system operation with the malfunctioning controls
Authors: Bogatyreva S.M. , Ilukhin S.N. , Toporkov A.G.
Published: October 2022

Orbital space telescope is a complex and expensive system. Electro-flywheel systems are used on such spacecraft as the orientation and stabilization system actuators making it possible to ensure the required accuracy of pointing an orbiting space telescope to a given region in the outer space. This paper considers the situation of failure of one of the flywheels on a spacecraft of the Hubble Space Telescope type. An algorithm for the orientation and stabilization system operation in such emergency was developed making it possible to ensure rotation of the spacecraft by a given angle with the remaining three controls functioning and without reducing the telescope pointing accuracy. A spacecraft model was created in the Simulink (MATLAB) dynamic simulation environment to develop this algorithm.

Inquiry into students' familiarity with computer-assisted translation tools
Authors: Abdi Hamidreza
Published: October 2022

Acquiring knowledge of computer-assisted translation (CAT) technology is the basic requirement not only for translation students but also for professional translators to have good use of CAT tools. This study aimed to investigate the degree of M.A. translation students’ familiarity with CAT tools used to support CAT-related activities included in the translator’s workstation. To do so, a questionnaire consisting of 16 questions was prepared for data collection based on translation activities proposed by Fulford and Granell-Zafar. This includes document production activities, business management activities and translation creation activities. As the results indicated, the M.A. translation students were mainly familiar with general-purpose applications, such as word processing software and machine translations, and rarely with specific-purpose software, namely web publishing software and accounting packages. They also were in full agreement with the effectiveness of CAT tools in their productivity and efficiency.
Keywords: Computer-assisted translation (CAT) tools, machine-aided translation, technology;
Evidence on Programmes that have Supported School Return for Disadvantaged Adolescent Girls
Authors: Amenya Donvan
Published: October 2022

This paper collates evidence on promising programmes that have supported school return for disadvantaged out-of-school girls in Rwanda and in other comparable low-and-middle-income country contexts. The review found evidence showing that interventions that address financial barriers which keep girls out of school delivered through cash transfers, stipends/fee waivers, and girls only scholarships can be effective in enhancing school return for disadvantaged girls. In addition, there is a strong evidence base showing that multi-faceted programmes that integrate health education, foundational skill training, vocational training, and financial literacy are effective in supporting school return for disadvantaged adolescent girls. While results from systematic reviews show that girls clubs can be effective in supporting school retention for disadvantaged girls, there is limited evidence on effectiveness of clubs in supporting school return for disadvantaged girls. The review found very limited evidence on effectiveness of financial and multi-faceted interventions in supporting school return for disadvantaged girls with disabilities.

Sumisión tácita, control de la competencia y compabilidad entre instrumentos jurídicos en litigios de compensación a pasajeros por cancelación de vuelo contra aerolíneas
Authors: Ruiz Martín Anna María
Published: October 2022

El entramado de varios instrumentos jurídicos para abordar la misma materia puede suscitar confusión en la práctica de cuál debe ser el de aplicación, así como también su posible aplicación simultánea. Esto sucede en la materia de contratos de transporte internacional de pasajeros por aire. Sin embargo, la jurisprudencia del Tribunal de Justicia de la Unión Europea (TJUE) ha establecido varios criterios para interpretar la compatibilidad de todos estos instrumentos jurídicos, en particular, sobre los posibles problemas procesales que el instrumento jurídico especial por razón de la materia aparentemente no regule y que los de corte general si regulan. En el Auto que se comenta, existen varias cuestiones importantes que merecen de análisis, como la falta o no de regulación de la sumisión tácita en los instrumentos especiales y el control de la competencia. Por otra parte, se discute la compatibilidad de los instrumentos especiales, cuando el pasajero-demandante invoca las acciones del Reglamento 261/2004 de forma simultánea a las comprendidas en el Convenio de Montreal 1999.

Some comments related to the international child abduction as regulated by the Council Regulation (EU) no. 1111/2019 and the Romanian Case Law
Authors: Anițe Nadia-Cerasela , Mareș Cristian
Published: October 2022

Considering that the international child abduction has increased nowadays, as it results from the Romanian case law, we have decided to study this part of the new Council Regulation (EU) 2019/1111 of 25 June 2019 on jurisdiction, the recognition and enforcement of decisions in matrimonial matters and the matters of parental responsibility, and on international child abduction (hereinafter referred to as the “Regulation No. 1111/2019”).

For this purpose, we shall also outline the differences between the Regulation No. 1111/2019 and the Council Regulation (EC) No. 2201/2003 of 27 November 2003 concerning jurisdiction and the recognition and enforcement of judgments in matrimonial matters and the matters of parental responsibility, repealing Regulation (EC) No 1347/2000 (hereinafter referred to as the “Regulation No. 2201/2003”), which shall be repealed by the Regulation No. 1111/2019 from the 1st of August 2022.

The international child abduction is included in the title of a regulation for the first time. As well, a special chapter related to the international child abduction was inserted – Chapter III, articles 22-29. This amendment included by the Regulation No. 1111/2019 is not only useful, but also natural, given that the issue of the international child abduction is a complete separate issue from the parental responsibility and the exercise of this responsibility.

The new Regulation No. 1111/2019 provides clarifications in relation to the period when the seised court must give its decision, in article 24, entitled Expeditious court proceedings.

In accordance with the legal provisions of both the Regulation No. 1111/2019 and the 1980 Hague Convention, for ordering the return of a child the following conditions must be met: (i) there has been a breach of the rights of custody, (ii) the person, institution or other body having the care of the person of the child was actually exercising the custody rights at the time of removal or retention, (iii) the child was habitually resident immediately before the wrongful removal or retention in the state where the return is requested, (iv) the person, institution or other body having the care of the person of the child had not consented to or subsequently acquiesced in the removal or retention, (v) no exception provided by articles 12 and 13 of the 1980 Hague Convention applies.
Panorámica y evaluación de la articulación en el ordenamiento jurídico español de las novedades introducidas por el Reglamento (UE) 2019/1111 en los procesos de restitución de menores
Authors: Calzado Llamas Antonio Jesús
Published: October 2022

La presente comunicación pretende contrastar las novedades más relevantes que introduce el Reglamento 2019/1111 en sus relaciones con el Convenio de la Haya 1980, con las normas españolas en la materia (especialmente, la Ley de Enjuiciamiento Civil). Se plantea, en primer lugar, la interacción normativa analizando los ámbitos material, espacial, personal y temporal. Seguidamente, se analiza la interacción en relación con el concepto de sustracción internacional de menores y sus principales componentes, como el concepto de traslado o retención ilícitos, el derecho de custodia y la residencia habitual. Finalmente, se evalúa la legislación española vigente a través de un contraste con las disposiciones del Capítulo III del Reglamento 2019/1111, dedicado a complementar el proceso de restitución de menores. A partir del análisis, puede concluirse que el nuevo Reglamento mejora el anterior marco normativo europeo, si bien ha de señalarse que el legislador español ya había regulado en nuestro ordenamiento jurídico una gran parte de esas mejoras.

Work-family conflict from the perspective of the family: Introduction to the Special Issue
Authors: Schulz Florian , Reimann Mareike
Published: October 2022

Objective: To introduce the readers to the Journal of Family Research's Special Issue (4/2022) about "work-family conflict from the perspective of the family".
Background: Research on work-family conflict rooted in family research and with an explicit focus on family issues has been comparatively rare compared to a more work-centered view.
Method: Except for the review article, all contributions of this Special Issue are quantitative analyses of large-scale data from Germany, i.e., the "pairfam"-study, the "LEEP-B3"-study, and the "Growing up in Germany"-survey.
Results: The seven studies are innately heterogeneous and show the range in which family research may contribute to the understanding of work-family conflict, and vice versa. Work-family conflict was studied in the context of the transition to parenthood, parenting practices, the composition of working environments, scaling back, mental health, and fertility preferences.
Conclusion: Explicitly discussing family issues and their implications for work-family conflict is necessary to understand the interdependencies between family and work, and to pave the way towards a much broader understanding of the antecedents and consequences of work-family conflict in the context of family living.
Mesenchymal Stem Cell Therapy and COVID-19
Authors: Rahman Fazliny Bt Abd
Published: October 2022

The coronavirus disease 2019 (COVID-19) caused by the novel, severe acute respiratory coronavirus 2 (SARS-CoV-2) has been spreading since late 2019 and has infected more than 360 million people worldwide. Infected individuals often develop severe illnesses, such as hypoxic respiratory failure and acute respiratory distress syndrome, which can lead to multiple organ failure. To manage the COVID-19 pandemic, vaccination programs have been conducted around the globe. In addition to supportive and antiviral medications, much attention has been focused on immunotherapies aimed at reducing pathological changes in the lungs. Currently, mesenchymal stem cells (MSCs) have received extensive attention as an option in treating COVID-19 because of their immunomodulatory, anti-inflammatory, and regenerative properties. This article discusses how MSCs play a major role in the battle against COVID-19, their pathological characteristics, their safety, and their possible effectiveness in treating the disease.
Radiographic Measurement of Normal Optic Nerve and Optic Nerve Sheath Diameters Using Different Modalities
Authors: Mohamed Ikhlas A , Wazir Ali Haifaa A , Abati Sahar M A , Alghamdi Salem Saeed , Bushara Lubna , Gareeballah Awadia , Osman Hanady Elyas
Published: October 2022

We aimed to review the role of different types of imaging (computed tomography [СТ], ultrasonography [US], magnetic resonance imaging [MRI]) in measuring the optic nerve diameter (OND) and optic nerve sheath diameter (ONSD) in adults and the potential advantages and limitations of each modality. A literature search was carried out using ResearchGate, Saudi Digital Library, Google Scholar, and Mendeley databases between 2010 and 2021 (papers presented in English) with the keywords “computed tomography,” “magnetic resonance imaging,” “ultrasonography,” “optic nerve sheath diameter,” and “optic nerve diameter.” Of the 60 articles analyzed, 42 were included in the review. Compared to ONSD, the evidence for OND appeared to be more limited. After comparing all three imaging modalities (CT, MRI, and US), we concluded that for the most accurate measurements of ONSD we should be using MRI (range: 4.0–6.0 mm). CT (range: 4.4–6.7 mm) would provide the second most exact measurements after MRI. Although CT and MRI provide the most consistent and accurate measurements, ultrasound is more commonly used (ONSD range: 3.4–7.7 mm) due to it’s being non-invasive, easy to use, and easily available anywhere, from big hospitals to small clinics, unlike CT and MRI. All three imaging modalities can provide good measurements, and hopefully, soon ultrasound will be as accurate as MRI in measuring the optic nerve.

Correlation of The Total Population of Black Soldier Fly (Hermetia illucens) Larva with The Population of The House Fly (Musca domestica) in Chicken Feces
Authors: Azhari Azhari , Kurniawan Evan , Riandi Lian Varis , Winaruddin Winaruddin , Jalaluddin M , Etriwati Etriwati
Published: October 2022

The increase in the house fly population (Musca domestica) indicates pollution from chicken farms due to the chicken feces produced. The house fly population from farms can be reduced by using Black Soldier Fly (BSF) larvae, but the exact number of BSF larvae has yet to be discovered to reduce the house fly population. This study aims to determine the presence of BSF larvae in chicken feces waste media in inhibiting the population of house flies. The research sample used 7-day-old BSF larvae from fishing for BSF flies from nature using organic waste to lay eggs and produce larvae. The research method used a completely randomized design (CRD) consisting of 4 treatments and 3 replications. Treatment without the addition of larvae (P0), 100 grams (P1), 200 grams (P2) and 300 grams (P3) into 1 kg of chicken feces stocked in a 50 cm x 50 cm container. The variable observed was the number of house flies perched on each treatment's feces. The results showed that the number of flies that landed on chicken feces with the addition of 0 g, 100 g, 200 g, and 300 g BSF larvae was 34.33±12.09, 22.33±10.21, 16.33 ±2.08 tails, 11.00±2.64 individuals. Based on the results of statistical analysis, it was found that the population of the house fly was significantly reduced (P0.05) between the addition of 0 grams of BSF larvae, 100 grams, 200 grams and 300 grams. The results of the study concluded that the more BSF larvae added, the less population of house flies perched around chicken feces. The presence of BSF larvae weighing 200 g per kg of chicken feces can reduce the population of flies that perch on chicken feces by 52%.
A Magnetic Levitation Turbine Generator for Downhole Electronic Devices
Authors: Fu Tao , Yang Qinghai , Yu Chuan , Li Ming , Liao Chenglong
Published: October 2022

With the popularization of electronic wellbore control devices, downhole power supply becomes more and more important. A downhole generator can transform the mechanical energy of underground fluid into electric energy, which is an ideal way to provide power for electrical devices. However, traditional generators have the disadvantages of large starting flow and short service life due to dynamic friction.

In this paper, a magnetic levitation turbine generator is introduced to solve the common problem of dynamic friction of packing in a shaft generator. In theory, downhole flow can provide the impact force to spin the turbine. However, the axial component of this force pushes the turbine into the supporting area so much that the friction between them may create too much resistance to start the rotation. To solve this problem, a magnetic levitation structure is proposed in this paper to provide a counterforce to the axial component of the thrust of flow, so that the turbine and the rotor core can float in the pipeline, thus completely eliminating contact friction and allowing free rotation of the turbine.

Through 3D printing, turbines of different blade numbers, and blade angles were manufactured. Three design schemes were assembled using these turbines. The experimental results showed that all the turbines can rotate smoothly at high speed and the magnet levitation structure worked well. The rotational stabilities of turbines with magnetic levitation structure at one end and two ends were compared. The experiment showed that the inertia of the turbine with magnetic suspension structure at both ends was greatly reduced and the rotation was more stable. At a flow rate of 100-150m3/d, the rotating speed of the turbine was 600-1500rpm. The output power was 73mW after, which is enough to charge the batteries of downhole electronic devices.

Using magnet levitation structure, the turbine generator can overcome the shortcoming of traditional downhole power generators. Such a new generator is expected to offer an intriguing alternative for long-term power supply of downhole electronic devices, which is an important prerequisite for the wellbore control to progress from mechanization to automation.

Low permeability, naturally fractured reservoirs such as coal seam gas (CSG, coalbed methane or CBM) and shale gas reservoirs generally require well stimulation to achieve economic production rates. Coupling hydraulic fracturing and micro-proppant or graded particle injections (GPI) can be a means to maximise hydrocarbon recovery from these tight, naturally fractured reservoirs, by maintaining or improving cleat or natural fracture conductivity. This paper presents a summary of the National Energy Resources Australia (NERA) project "Converting tight contingent CSG resources: Application of graded particle injection in CSG stimulation" - which assessed the application of micro-proppants, providing guidance on key considerations for GPI application to CSG reservoirs.

Over the last decade, laboratory research and modelling have shown the benefits of the application of GPI to keep pre-existing natural fractures and induced fractures open during production of coal reservoirs with pressure dependent permeability (PDP). Laboratory studies, within this study, provide further insight on potential mechanisms and key factors, including proppant size and optimum concentration, which contribute to the success of a micro-proppant placement. Accompanying numerical modelling studies will be presented that describe the likely fluidized behaviour of micro-proppants (e.g., straining models, electrostatic effects, and ‘screen out’ prediction).

This paper outlines the necessary reservoir characterization, treatment considerations, and key numerical modelling inputs necessary for the design, execution, and evaluation of GPI treatments, whether performed standalone or in conjunction with hydraulic fracturing treatments. It also provides insight on the practical application of GPI efficiently into fracturing operations, minimizing natural and hydraulic fracturing damage effects, thereby maximizing potential production enhancement for coals, shales and other tight, naturally fractured reservoirs exhibiting pressure-dependent permeability effects.

Renewable energy is becoming an integral part of our energy supply; however, seasonality and weather dependence are some of their major limitations. Therefore, grid integration with reliable storage systems is crucial. One promising energy storage technology is green hydrogen generation and storage. Some research has been ongoing into hydrogen storage in underground porous media, but it mostly lacks comprehensive dynamic modelling of the storage operation and the associated potential losses.

In this work. a holistic hydrogen storage operation in a heterogenous depleted gas reservoir and its likely associated underground losses was modelled. Fluid model verification was performed to assess the suitability of a typical equation of state to represent hydrogen behavior at reservoir conditions. The study aimed to assess the feasibility of storing 15% of the renewably generated power in Malaysia for grid-scale equilibration purposes.

A total of 12 storage cycles with potential diffusion and biochemical losses were simulated. The storage operation performed effectively in all the key performance indicators. 68.1% of the injected storage volume was recovered by the 12th cycle. It was observed that the purity of the produced hydrogen is influenced by reservoir heterogeneity. Lastly, it was found that storing 15% of Malaysian renewable energy in a depleted gas reservoir was technically feasible.

Advances in drilling equipment, drill bit design, and PDC cutter technology have resulted in significant time savings through increases in penetration rate and the entire hole section being completed in a single bit run. However, the wellbore condition has become an important consideration as the time spent to improve the quality of the wellbore to facilitate tripping and running casing is increased.

The paper discusses a case study in the Jatiasri and Akasia Bagus fields, West Java, Indonesia, where both the 17½-in. and 12¼-in. hole sections are considered challenging. Pipe stall, overpull, stuck pipe, and tight spots are typically experienced during drilling and tripping, resulting in difficult trip-out and subsequent trip-in with casing. Those two case studies describe poor borehole conditioning related to micro-doglegs or tight hole issues.

A unique bi-directional eccentric reamer tool was introduced to help improve the wellbore quality. The tool removes or smooths out irregularities in the wellbore geometry during drilling and reaming operations. To work effectively, the correct placement within the BHA is critical. Using proprietary multifunctional advanced placement software, the reamer is ensured to be optimally placed while analyzing bending stresses and contact forces throughout the run for safe and trouble-free operation.

The run results showed significant time savings in pulling out of hole by 38 to 91% in the 12¼-in. section and 20 to 57% faster in the 17½-in. section compared to the offset runs. In addition, wiper trips can be eliminated or greatly reduced, and casing speed is also improved. The casing shoe was also set or landed close to the designated depth, eliminating the need for dedicated cleanout runs. For more than 17 runs, the performance showed consistency in time savings while reducing the potential for stuck pipe, string stall, and tight spots.

This unique bi-directional eccentric reamer has added a new capability for drilling improvement and optimization through borehole conditioning, reducing nonproductive time and interval costs which ultimately contributes to lower well construction cost.

Sand production prediction analyses were carried out at different stages of the development of Geographe field in Otway Basin, Australia. The analyses were conducted from very early stages of development in 2010 and carried on until 2019 using different sets of data. The exploration and appraisal wells data were used to conduct an early sanding analysis in 2010. The study showed low risk of sanding for the planned wells following the planned production. The sand production prediction model was then updated in 2014. Several additional data such as well logs, core tests and sand-free production data from the early production wells were used to improve the 2010 sanding model. The updated model also showed low risk of sanding for planned horizontal wells and suggested no sand control would be required even at high depletions. The last model update in 2019 was improve by using the production data from two long horizontal laterals. The updated model was used to assess the completion design for an approximately 2.1 km long horizontal well. Because the updated sanding model showed negligible risk of sanding for the planned well, a lower sand-face completion with pre-drilled liner was recommended for the completion system. The stability of the interbedded shale layers intersecting the horizontal section is also assessed. The result suggested that the shale layers fail under the downhole production condition. Hence, it was recommended to use packer and blank pipe against shale sections to mitigate the failure in the non-reservoir intervals. The well was eventually drilled and successfully completed in latter part of 2021. The progressing sanding analyses helped to enhance the reliability of the early prediction analysis by calibrating against the actual production data from the two horizontal wells. The sanding and shale stability analyses are used to confirm suitability of the completion system for the well throughout the entire life of the field at high pressure depletion condition.

Foam-assisted water-alternating-gas (FAWAG) or Enhanced WAG (EWAG) has been identified as one of the methods to improve WAG performance by reducing mobility of its gas phase through foam introduction, hence improving overall sweep efficiency. Foam generation in porous media has been thoroughly studied at fundamental level, and a few mechanisms being proposed (Falls et. al. 1998, Boos et. al. 2012). Ability to sustain and propagate foam in porous media such as reservoir rock is still a subject of investigation.

Literature suggested the addition of nanoparticles into foaming surfactant formulation can potentially improve foam performance in stability and assist propagation in porous media. Silica dioxide (SiO2) has been the commonly used nanoparticle for oil and gas application, including for FAWAG application (Agista et. al. 2018). It is not difficult to understand silica oxide selection for two main reasons. First, for a sandstone reservoir, silica makes up majority of quartz in rock mineralogy. Second, it is relatively cheaper as compared to the other nanoparticles.

The study objectives can be summarized in two parts. Firstly, to test the stability of nanoparticle-foams in relation to its hybrid chemical formulation. Secondly, to validate nanoparticles as foam phase stabilizer during foam propagation in porous media. The study utilized in-house designed and manufactured surface treated silica oxide nanoparticles and in-house fabricated long core core holder equipment. It was observed that the introduction of nanoparticles can assist foam performance and propagation in porous media.

As part of circular model for E&P, production sand waste from oil production process will be converted to new high value-added product, called "Nanosilica", and "Hierarchical Zeolites". This is beneficial in terms of lower amount of production sand waste disposal to landfill.

There are three main steps for sand conversion to nanosilica and hierarchical zeolites which compose of1) Sand Pre-treatment, 2) Nanosilica Extraction, and 3) Hierarchical Zeolite Synthesis. In the first step of Sand Pre-treatment process, production sand was pretreated by using water and acid washing 3M HCl, follow by calcination. Secondly, pretreated sand will be extracted to obtain nanosilica by boiling pretreated sand with 3M NaOH solution to get sodium silicate, and finally adding HCl to precipitate nanosilica. Finally, the extracted nanosilica will be further reacted with Structure Directing Agent (SDA); zeolite template, under hydrothermal treatment process for crystallization of Hierarchical Zeolites.

Nanosilica extracted from production sand contain high specific surface area around 200 – 600 m2/g, with small particle size less than 50 nm. Nanosilica can be applied in many applications such as Gas separation, Adsorption, Catalysis, Ion-exchange, and Detergent.

Hierarchical Zeolites with nanosheets morphology obtain many niche characteristics to overcome the limitation of conventional zeolites in terms of, 1) good mass transportation through active sites due to their microporous structure improvement, 2) high surface area, and 3) longer catalyst lifetime.

Hierarchical Zeolites is popularly used in wide range of applications such as separation, ion-exchange to catalysis. Two most popular Hierarchical Zeolites nanosheet ZSM-5, and Faujasite (FAU) topologies have been developed in this work. The physicochemical properties were compared with the one synthesized using the commercial chemical grade of silica sources. The results show that the nanosilica from production sand can be achievable for Hierarchical Zeolites synthesis, by comparing the physicochemical properties such as surface area, porosity, topology, and textural properties with the one obtained using the commercial silica sources.

Hierarchical zeolites from production sand waste are initiated in PTTEP as part of Circular Model for E&P. The synthesized hierarchical zeolites from this project will be further possibly applied in-house in PTTEP as the moisture adsorbent in instrument air, or moisture in condensate. This would help company for reduce OPEX cost. From these preliminary findings, all information will be further applied to the process design of in prototype, and scale-up phase.

To capture the invaluable tacit knowledge from skilled operators and leverage on insights generated from over two decades of plant operation data, an AI-driven live advisory was developed to provide operators with real-time parameters control advisory during start-up, in response to actual process and equipment conditions. The solution had been deployed to ten start-ups in Malaysia LNG, successfully achieving 44% reduction in duration and 17% reduction in carbon emission from reduced gas usage. The shorter start-up duration translated into significant value creation from production opportunity, yielding an impressive return on investment of 35, in just 15 months. Furthermore, six of the start-ups also emerged as the top executions when benchmarked against all historical occurrences in the past two decades, demonstrating its ability to enable consistent and optimised start-ups.
