Article Preview

Based on the recovery of vent gases for current popularity of small skid-mounted natural gas liquefaction process, in this paper, the nitrogen gas expansion refrigeration process and natural gas cooling self-expanding processes was simulated respectively. The main parameters of flow rate, power and temperature for the different refrigeration process are obtained also, and influence of different refrigeration process on performance and cost of recovery device. The simulation results show that the cycle of natural gas self-expansion with pre-cooling is used to recovery BOG gas with high efficiency, and simple operation. This cycle with pre-cooling will apply the cold energy of BOG efficiently.
