Authors: Robert Ubong Williams , Etuk Sunday Edet , Agbasi Okechukwu Ebuka
Published: December 2024

In this research work, a modified water displacement method (MWDM) was designed and used in addition to geometry method (GM) to measure the bulk volume and then determine the bulk density values of asbestos ceiling board, cardboard paper, chalk, clay (compacted) and gypsum board that have been sun-dried to constant weight. The mean bulk densities determined by both methods were compared with the reference bulk density values of the same porous materials obtained in this work using standard test procedure in accordance with ASTM D6683-14. It was observed that, for all the tested porous materials, the percentage error in the mean bulk density values ranged from 2.3% to 49.6% when using GM and 0.9% to 5.7% by using the MWDM. Also, at 0.05 level of significance with a degree of freedom of 3, correlation coefficients of 0.7430 and 0.9955 were obtained in the cases of GM and the MWDM respectively. Again, all other analyses performed similarly revealed that the mean bulk densities obtained by the MWDM only were in close agreement with their corresponding reference values, thereby implying that apart from being cost-effective, the MWDM is better than GM in terms of accuracy, reliability, and validity. More importantly, it is noteworthy that even if the glass cylinder available for use is ungraduated, this MWDM can be employed to obtain accurate, reliable and valid bulk density values of porous materials in order to enhance thorough physical characterization, proper selection and suitable applications of such materials.

Teknologi destilasi (penyulingan) air untuk mendapatkan air tawar dari air kotor atau air laut intinya adalah menguapkan air laut dengan cara dipanaskan, yang kemudian uap air tersebut diembunkan sehingga menjadi air tawar. Proses kerja destilator terdapat juga kelemahan yaitu dari proses penguapan destilator, uap yang dihasilkan lalu diembunkan menjadi butiran air yang menempel dikaca. Selanjutnya butir air bertemu dengan butir-butiran air yang lainnya dan menghasilkan butir air yang memiliki berat air berlebih sehingga sebelum butir air tersebut sampai ke dalam penampungan, butir air tersebut akan terlebih dahulu jatuh. Begitu pula dengan semakin panjangnya destilator akan mempengaruhi penguapan jatuhnya butir air sebelum jatuh ke dalam penampungan. Penelitian ini bertujuan untuk mengetahui panjang optimum destilator tenaga surya. Penelitian ini menggunakan panjang optimum dari 500 mm, 600 mm, 700 mm, 800 mm, 900 mm, dan 1000 mm sebagai panjang yang akan dianalisa. Proses penguapan tersebut akan mempengaruhi dari sistem destilasi dan kuantitas air yang dihasilkan. Dari hasil pengujian yang memiliki panjang optimum terhadap kuantitas air hasil yang terbanyak yaitu pada panjang 70 cm sebesar 1678 ml.
Hal ini disebabkan oleh air pada basin yang sudah diuapkan harus diembunkan (kondensasi) supaya uap jenuh tersebut melepaskan kalor laten agar menghasilkan kuantitas air hasil yang maksimal. Dari hasil pengujian dan perhitungan yang memiliki panjang optimum terhadap unjuk kerja terbaik  pada destilator tenaga surya yaitu  adalah panjang 70 cm, karena laju energi saat penguapan sebesar 127,6 Watt, laju energi saat pengembunan sebesar 124,02 Watt, laju destilasi dalam proses destilasi sebesar 0,0000517 kg/s, efesiensi produk destilasi sebesar 11,65%, dan efesiensi sistem destilasi sebesar 38,2%.

Authors: Musnal Ali , Fitrianti
Published: December 2024

In producing oil, one of the common problems faced by oil and gas companies is the production of a lot of water. Increased water production causes the storage tank to be unable to accommodate the produced water. To overcome the excess water production, some of the water is injected back into the well. In Field A, an innovation has been made for a water injection pump with the driving force coming from the Electrical Submersible Pump (ESP) pump. The working principle of this ESP pump is to drain water from the disposal well to the injection well. Therefore, in order for the injection to run optimally, synchronization is carried out starting from the water entering the holding tank, the flow rate in the Disposal well and the pump capacity (ESP) for injecting from the holding well to the injection well.
The amount of water flow rate injected through the ESP pump is 9,500 BWPD. For this reason, the capacity of the ESP pump as an injection pump is calculated. First, determine the water level in the tank to control the amount of flow that enters the reservoir well.
Based on the results of the research that has been done, the water level in the holding tank to get a flow rate of 9,500 BWPD is 4.11 ft. And the results of the calculation of water will be injected using an ESP pump with a number of stages 22 with the TRW Reda Pump Devision pump type. The water will be channeled to the injection well with a type of galvanized iron pipe with a diameter of the main pipe (mainline) of 6 inches. From the disposal well, it flows with a 4 inch pipe as far as 45.93 ft and a 2 inch pipe as far as 2214.57 ft for well 07. As for wells 60, the flowline size is 4 inches as far as 708.66 ft and 2 inches as far as 987.53 ft.
