Solubility of methane in Louisiana Sweet Crude oil at 20 °C

The solubility of methane in Louisiana Sweet Crude oil (LSC) was determined at 20 °C at varying pressures between 3 and 16 MPa. The gas saturation was determined gravimetrically, using a microbalance for detecting the gas uptake of the liquid phase at given pressure and temperature until equilibrium was reached.本研究在20 ℃、3~16 MPa的可变压力条件下，测定了甲烷在路易斯安那甜基原油（Louisiana Sweet Crude oil，LSC）中的溶解度。实验采用重量分析法测定气体饱和度：在指定的压力与温度条件下，通过微量天平监测液相的气体吸收量，直至达到气液平衡。
