The gas flows up the casing, and if the well is pumped off, there is no liquid at the bottom of the casing. Pumping the height of fluid over the pump to lower levels, lowers the pressure on the well formation as well as any dewatering method unless the pump has gas or solids or ot...
while this cryogen exists in single unique state, is sometimes used as one constituent of Liquified Natural Gas (LNG) [24,25], a mixture comprised of (by mole fraction) ~89.7% LCH4, ~6% liquid ethane, ~3% liquid propane, with the balance including liquid iso-butane, liquid butane, and...
The relative deviations of the experimental densities of propane from values cal- culated with the equation of state by Lemmon et al. [110] are plotted versus pres- sure in Fig. 3(c). All experimental data points with p ≥ 60 MPa are within a maxi- mum relative deviation ...
Ideal gas - partial pressure of a component is equal to the vapor phase mole fraction times total pressure, Raoult's law - partial pressure of a component is equal to the liquid phase mole fraction times the saturation pressure, The last two assumptions lead to a relationship ...
performed as per the manufacturer’s protocol. Briefly, the cells were visualized using the forward scatter (FSC-A) versus red fluorescence intensity (FL2-H) scatter plot and a gate was applied to determine the percentage of live and dead cells (Supporting FigureS14). 100 µl of cell ...
9. It is seen that H2 and CO were the major products, that low molecular weight hydrocarbons (methane, ethane, ethylene, propane and propylene) were present in acceptably low concentrations if at all, and oxygen was completely consumed. It was surprising that the system could be operated in ...
(SOFC) and runs on liquefied petroleum gas or propane. While this allows a greater fuel fraction and reduced fuel tank weight compared tocompressed hydrogen, the reportedfuel cell efficiencyis relatively low (18.8%), start-up times are around 20 min due to the high operational temperatures, ...
The article discusses the decision of the Ohio Supreme Court on the case, Moulton Gas Service Inc. versus Zaino, regarding the tax treatment of bobtail tanks mounted on liquid propane delivery trucks. The facts of the case are discussed. The findings of the Ohio Board of Tax Appeals and the...
FIG. 4 is a graph depicting conversion selectivity percentage versus TOS in days; FIG. 5 is a schematic diagram depicting components used to convert ethane gas to liquid fuels; FIG. 6 is a schematic diagram depicting components used to convert ethane gas to liquid fuels; and ...
A heavy gas/liquid spill and dispersion modelling system has been developed for estimating the hazard zones due to accidental spills of flammable or toxic chemicals such as propane, butane, chlorine and ammonia. It consists of three basic modules: the spill rate module for estimating the direct ...
