Abstract
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.
