Nitrogen rejection from low quality natural gas by pressure swing adsorption experiments and simulation using dynamic adsorption isotherms
文献摘要：
In order to remove N2 from low quality natural gas,a mathematical model has been established by Aspen adsorption,using the CH4-selective sorbent silicalite-1 pellets.The dynamic adsorption isotherm was first simulated by breakthrough simulation of a CH4/N2 mixture at different adsorption pressures and feed flow rates based on breakthrough experiments.The resulting simulated CH4 dynamic adsorption amounts were very close to the experimental data at three different adsorption pressures(100,200,and 300 kPa).Moreover,a single-bed,three-step pressure swing adsorption(PSA)experiment was per-formed,and the results were in good agreement with the simulated data,further corroborating the accu-racy of the gas dynamic adsorption isotherm obtained by the simulation method.Finally,based on the simulated dynamic adsorption isotherm of CH4 and N2,a four-bed,eight-step PSA process has been designed,which enriched 75％(vol)CH4 and 80％(vol)CH4 to 95％(vol)and 99％(vol),and provided 99％(vol)recovery.
