Description:
The report gives results of a theoretical investigation of the disposition of five volatile trace elements (arsenic, boron, lead, selenium, and mercury) in SNG-producing coal gasification plants. Three coal gasification processes (dry-bottom Lurgi, Koppers-Totzek, and HYGAS) were investigated to examine the possible effects of gasifier operation conditions on the speciation of the volatile trace elements. Results of this investigation suggest that none of the trace elements considered in this study will be present in the product SNG from a coal gasification plant, but will be removed from the fuel gas by various unit operations. Results also suggest that speciation of these volatile trace elements is not significantly affected by gasifier conditions.
