Process Design And Mathematical Simulation Of The PSA Concentrated Methane Gas

Coal seam gas is a high-quality gaseous fuels and chemical raw materials, whose main component is methane, or coal mine mining disaster factors and cause the harmful source of the atmospheric greenhouse effect. Effective use of methane in methane gas, provided that its concentration. The principle of using gas multi-component gas (CH4/N2) adsorption on carbon molecular sieve with the pressure changes, designed a six column pressure swing adsorption unit, test equipment can be used as a pressure swing adsorption, the maximum daily processing of CH4/N2mixed gas780m3, reasonable running costs, good gas tightness, high degree of self-control, the continuous output of the high concentration of methane.The pressure swing adsorption gas separation technology is based on the development and application of efficient solid adsorbent, the adsorbent performance directly affects the separation of the pressure swing adsorption process. Phenolic resin as raw material by chemical vapor carbon deposition tone holes117-1Preparation of carbon molecular sieve, its CH4/N2binary mixture separation factor of≥4, can be applied to the methane gas in the methane pressure swing adsorption separation and concentration of research.PSA process is complicated and changeable, the operation variables coupled to each other, difficult to visually draw the impact of variables on the separation, therefore we need to establish a credible, able to express the mathematical Simulation of the system dynamics. The adsorption isotherms of CH4, mathematical Simulation to optimal choice of the operating process of pressure swing adsorption, and the optimal design of adsorption column is of great significance.Figure17, Table20, Ref55...
