A novel electricity- Compressed Natural Gas (CNG) multi-compression process using natural gas pressure energy is proposed. Compared to electricity-CNG single-compression process using natural gas pressure energy with the same CNG product, the multi-compression process produces 92 more kW power. In this paper, exergy analysis and energy utilization diagram method (EUD) are used to assess the new process and identify the key operation units with large exergy loss. The results show that exergy efficiency of the multi-compression process is 57.9%. Compared to the single-compression process, exergy efficiency of the new process is improved by 50.4%. The proposed process has been applied and implemented in a conceptual design scheme of the pressure energy utilization for a 37.5 million Nm3/year CNG-compression station in some northern Chinese city.
