It showed that the propane recovery rate of new process would be 23%~27% higher than that of cryogen refrigeration process at the same refrigeration temperature. To increase the absorption tower pressure appropriately was good to improve the propane recovery rate. However, the choice of pressure must take the pressure of the feed natural gas and product gas into account together. The flow rate of absorbent had great effect on propane recovery rate and tower heat load.
