激冷流程气化技术循环气压缩机设备布置的合理性分析

在全世界范围内已实现工业化生产的煤气化技术中,只有壳牌煤气化技术采用了激冷流程,由于该工艺在节能减排降本增效方面突出的优势,未来其他新型煤气化技术也存在采用此工艺的可能。分析和论述了以壳牌煤气化技术为代表的粉煤气化技术(激冷流程)的优势及其广阔的应用前景,着重对目前壳牌煤气化装置循环气压缩机的布置进行分析,对比国内现行的防火设计规范,论证了现有循环气压缩机的布置方案是满足国内现行设计规范要求的,为未来中国其他采用激冷流程的新型煤气化工艺的研究与发展奠定坚实的理论基础。 As one of the coal gasification technology having realized industrial production,Shell coal gasification process is the only one adopting chilling process.It's advantages in energy saving and consumption reduction would broaden its application in other gasification process in the future.Emphasize the layout of recycle gas compressor in chilling process.The results show that the layout of compressor meets the requirement of fire prevention at home.The research could provide the theoretical reference for other coal gasification technology with chilling process
