抽放煤层气变压吸附过程的数学模拟

Numerical simulation of pressure swing adsorption processes for coal bed gas extracted

建立了变压吸附过程的非等速、非线性等温平衡模型 ,并对浓缩抽放煤层气中CH4 的变压吸附过程循环进行了数值模拟 ,理论计算结果与实测数据相符 ,表明本模型是适用的 .利用该模型详细讨论了吸附柱内CH4

A equilibrium mathematical model with non - constant flow and nonlinear isotherm was developed for the bulk separation of the extracted coal bed gas. The predicted performance appears consistent with the experimental results, which shows that the model is applicable. The gas and solid phase concentration profiles in the bed were also discussed in detail.
