Reactive S (e.g. H.sub.2 S and mercaptans) in petroleum liquid are scavenged by the use of oil soluble trialkyl hexahydro triazines wherein at least one alkyl group, and preferably all three, contain from 7 to 20 carbon atoms.

Removal of H.sub.2 S hydrocarbon liquid

A composition and process for the removal of mercaptans from gaseous mixtures, particularly gaseous mixtures containing hydrocarbons, wherein the gaseous mixture is treated with an aqueous solution of a water soluble nitrite, such as sodium nitrite, and a water soluble polysulfide, such as sodium tetrasulfide, the pH of the aqueous solution preferably being about 10 or greater initially.

Process and composition for removal of mercaptans from gas streams

Process for removal of mercaptans from gas streams

Process for the removal of hydrogen sulfide from gas mixtures, particular gas mixtures containing hydrocarbons, wherein the gas mixture is treated with an aqueous solution of a water soluble nitrite such as sodium nitrite, the pH of the aqueous solution being at least 5.5 or greater.
