Tail Gas Cleanup Process technology
The Claus process has been used in industry for well over 100 years for the purpose of handling hydrogen sulfide and converting it to elemental sulfur. The Claus process goes a long way toward being a major contributor to air pollution abatement. However, with the advent of more stringent environmental regulations and pressure from environmental groups, it has been necessary for industry to develop a whole series of processes which are called Tail Gas Cleanup (TGCU) Processes. These TGCU processes typically are positioned after a Claus Unit in order to increase the overall recovery of the Claus plant and to reduce SO/sub 2/ emissions simultaneously. The accelerated development of population centers is typically demanding increased industrialization. These new industries require energy sources. The energy sources usually have some form of hydrogen sulfide or elemental sulfur associated with them. The burning of high sulfur-bearing coal for the production of electricity, the refining of high sulfur-content crude oil, and the processing of sour natural gas are all causing an increase in the attention given to reducing the emissions of SO/sub 2/ from the tail gas of Claus Sulfur Recovery Units (SRU's). The sulfur produced from hydrogen sulfide commonly associated with sour natural gas or sour crude oil is an ever increasing proportion of the world's supply of elemental sulfur, because the traditional naturally occurring sources are being exhausted and the Frasch process, used to recover such naturally occurring sources, is very energy inefficient.
