Methyl diethanolamine (MDEA) is a tertiary amine that has the capability to selectively remove H/sub 2/S from natural gas while leaving the bulk of the CO/sub 2/ present in the residue gas stream. Known areas of application for MDEA plants include the enrichment of sulfur plant feed, recovery of H/sub 2/S from sulfur plant tail gas, and treating of natural gas for selective removal of H/sub 2/S. Goar and others have discussed the benefits associated with sulfur plant feed enrichment. This paper discusses the results taken from an operating MDEA gas treater that was designed to slip 50-60 percent of the CO/sub 2/ in the inlet feed to residue and still meet the specification of 1 grain/1-0 SCF H/sub 2/S. It is demonstrated that the H/sub 2/S in the residue gas did not change at any circulation rate until the stripping rate on the stripper dropped sufficiently low. CO/sub 2/ slippage decreased as the circulation rate increased. H/sub 2/S removal to less than 1 ppm in the residue gas is maintained at amine temperatures as high as 145/degree/F. CO/sub 2/ slippage decreased as amine temperature increased. 3 refs.
