In this paper, SNG production technologies are investigated and summarized. A new SNG production process has been developed. It has advantages in performance, cost and operability. The performance of the new process is analyzed and compared with two existing processes — one process based on hydrogasification and one conventional SNG production process. Based on process modeling, exergy analysis is carried out to identify the specific loss of each sub-process. The thermodynamic features of the new process are investigated to show the trend of the parameters of the hybrid gasifier and the whole process. A concept of critical conversion rate is identified and defined. Key parameters of hybrid gasifier and thermal performance of the system are examined and presented. Besides thermal performance, other issues related to operation and cost are discussed.
