Published: April 2014

In order to reduce the production cost of biodiesel, the transesterification process under ultrasound-assisted condition is studyed in this paper by using heterogeneous solid base catalyst NaAlO3/Al2O3 instead of the traditional homogeneous catalyst. Through one-factor experimentation, ultrasonic frequency, oil-alcohol molar ratio, catalyst amount and reaction time on the yield of biodiesel are examined. Transesterification conditions are optimized through orthogonal experiment and the effect order of four factors is as follows: ultrasonic frequency >molar ratio of methanol to oil > reaction time > the amount of catalyst. Results show that the amount of catalyst and reaction time are reduced under ultrasound-assisted condition, and the optimum preparation conditions are: 20min of reaction time, 28KHz of the ultrasonic frequency, molar ratio of methanol to oil 9:1 and 2% catalyst. Under above conditions, the yield of biodiesel reaches 95.21%.

Published: April 2014

Dynamic compaction is a widely used foundation reinforcement technique. But the energy of the foundation spreading around in the earth by the form of wave will produces bigger effect of vibration on the surrounding environment. It brings a lot of adverse effects to nearby residents life, work, and even to the safety of the surrounding buildings. In actual engineering, we often determine the feasibility of the dynamic compaction construction scheme by the compaction test, which is time-consuming and laborious. Based on the monitoring of stadium area soil compaction in the new campus of Wuhan University of Technology, we use dynamic finite element software named LS-DYNA to simulate the dynamic compaction construction and establish a set to conform to the model parameters of the actual project. We can change the tamping compaction model according to the different adjusting scheme to guide the construction.

A series of waterborne polyurethane (WPU) with different soft segment structures were sythesised, and the effects of the structure and molecular weight of the soft segment on the degree of PU microphase separation were evaluated by the infrared spectroscopy (FTIR) computer peak fitting. The experiment results indicated that phase separation between hard and soft segments of poly (ether–urethane) was more significant than poly (ester–urethane), based on the qualitative analysis on the N–H stretching region of the FTIR spectrum. And the qualitative analysis on the carbonyl stretching region showed that PU with lower soft segment molecular weight had a higher relative amount of hard segment, and possesses higher microphase separation degree. The addition of polyether soft segment PEG had an internal plasticization by actuating the PCD molecular chain. Therefore, it becomes easier for PU to conduct structure adjustment and increased the phase separation degree.

Foam flooding is an established approach in Enhanced Oil Recovery (EOR) to recover a significant quantity of the residual oil left in the reservoir after primary and secondary recovery. However, foam flooding faces various problems due to low viscosity effect, which reduces its efficiency in recovering oil. Using surfactant to stabilize CO2 foam may reduce mobility and improve areal and vertical sweep efficiency, but the potential weaknesses are such that high surfactant retention in porous media and unstable foam properties under high temperature reservoir conditions. Nanoparticles have higher adhesion energy to the fluid interface, which potentially stabilize longer lasting foams. Thus, this paper is aimed to investigate the CO2 foam stability and mobility characteristics at different concentration of nanosilica, brine and surfactant. Foam generator has been used to generate CO2 foam and analyze its stability under varying nanosilica concentration from 100 - 5000 ppm, while brine salinity and surfactant concentration ranging from 0 to 2.0 wt% NaCl and 0 – 10000 ppm, respectively. Foam stability was investigated through observation of the foam bubble size and the reduction of foam height inside the observation tube. The mobility was reduced as the concentration of nanosilica increased with the presence of surfactant. After 150 minutes of observation, the generated foam height reduced by 10%. Liquid with the presence of both silica nanoparticles and surfactant generated more stable foam with lower mobility. It can be concluded that the increase in concentration of nanosilica and addition of surfactant provided significant effects on the foam stability and mobility, which could enhance oil recovery.

In deepwater drilling, there are two major components of drilling tools that are subjected to vibration, namely the marine riser and the drilling pipe. Analyses of vibration in the marine riser and drill pipes are two topical areas that have individually received considerable attention by researchers in the past. For the marine riser, the focus was on the vortex-induced vibration (VIV) in different shear and flow regime. The focus on the drill pipes was on different vibratory modes and resonance. While these two subjects are interrelated, they have been little attempt to investigate them together as an assembly. The present paper investigated the coupling of the marine riser VIV to the drill pipe vibration when the drill bit penetrated the wellbore using coupled approach. It was found that the lateral displacement of drill pipe is most significant when the riser oscillates at lower frequency. Riser oscillation is most damaging to the drill pipe when the later also rotates at low RPM.
