Résumé

Compared with ordinary natural gas, coalbed methane (CBM) usually has more impurities, and this makes the liquefaction process different. The liquefaction process of nitrogen expansion with propane precooling is discussed, which is suitable for small liquefaction plants. The unit product liquefaction power consumption is taken as the major index for analysis. By means of computation and HYSYS simulation, the effect of the nitrogen content on the liquefaction process is then studied when the liquefaction and methane recovery rates are fixed. Finally, on the basis of a previous analysis, an integrated CBM nitrogen expansion liquefaction process with propane precooling is proposed with HYSYS simulation analysis.
