Recent advance in Claus plant tail gas clean-up for air quality improvement

摘要

Overall sulphur recovery yields of 99.8% can be attained using Clauspol II technology, which is a tail gas treatment process. H(sub 2) S and SO(sub 2) in Claus effluents are removed in a simple, low capital operating cost process that uses no hydrogen and low utilities. The continuous withdrawal of product sulphur explains the high efficiency of the process. 2 figs., 1 tab.
