Abstract
Sour sulfhydryl group containing oils and gases are treated with an effective amount of a sweetening, hydrogen sulfide quantity reducing aminocarbinol of the formula EQU R.sub.2 N--CH(--R.sup.1)OH wherein R.sup.1 is hydrogen or a hydrocarbyl or inertly substituted hydrocarbyl and each R is independently hydrocarbyl or inertly substituted hydrocarbyl or both R groups are collectively a divalent hydrocarbon or ether radical combined with the nitrogen of the aminocarbinol to form a heterocyclic ring represented by the formula EQU (--R--R--)>N--CH(--R.sup.1)OH. The aminocarbinols used in this treatment are especially suitable for sour gases and high boiling, heavy residual fuels under low mix conditions.
