Technical and Economic Analysis of Supercritical Water Oxidation and Biochemical Process for Lurgi Coal Gasification Wastewater Treatment

Abstract:

The technical and economic analysis of supercritical water oxidation (SCWO) and biochemical process for Lurgi coal gasification wastewater (LCGW) treatment were carried out. The findings include the analysis of flow sheet, effluent quality and operation cost of the two processes. Studies show that the SCWO process is more simply and easier to control than the biochemical process. The effluent treated with SCWO process could reach national discharge standard I (GB 8978-1996) without other pretreatment and advanced processes, and could gain 2.3 yuan RMB/t(LCGW). While the operation cost of biochemical treatment is 41.8 yuan YMB/t(LCGW). The SCWO process shows a unique advantage in both technology and economy and will be a promising technique for LCGW treatment.
