Abstract
Methods are disclosed for selectively reducing the levels of hydrogen sulfide and oragnic sulfides from gaseous and/or liquid hydrocarbon streams, particularly natural gas streams, compromising contacting the streams with a composition comprising the reaction product of (i) a lower alkanolamine with (ii) a lower aldehyde.
Claims21
A method for selectively reducing the levels of hydrogen sulfide and organic sulfides present in gaseous or liquid hydrocarbon streams or mixtures thereof comprising contacting said streams with a composition comprising the reaction product of (i) an alkanolamine comprising 1 to about 6 carbons with (ii) an aldehyde comprising 1 to about 4 carbons, for a period of time sufficient to reduce the levels of hydrogen sulfide and organic sulfides in said streams.
A method for selectively reducing the levels of hydrogen sulfide, organic sulfides and water present in gaseous or liquid hydrocarbon streams or mixtures thereof comprising contacting said streams with a composition comprising (1) the reaction product of (i) an alkanolamine comprising 1 to about 6 carbons with (ii) an aldehyde comprising 1 to about 4 carbons and (2) a glycol, for a period of time sufficient to reduce the levels of hydrogen sulfide, organic sulfides and water in said streams.
A method for selectively reducing the levels of hydrogen sulfide and organic sulfides present in gaseous or liquid hydrocarbon streams or mixtures thereof comprising contacting said streams with a composition comprising a triazine, for a period of time sufficient to reduce the levels of hydrogen sulfide and organic sulfides in said streams.
A method for selectively reducing the levels of hydrogen sulfide, organic sulfides and water present in gaseous or liquid hydrocarbon streams or mixtures thereof comprising contacting said streams with a composition comprising a triazine and a glycol, for a period of time sufficient to reduce the levels of hydrogen sulfide, organic sulfides and water in said streams.
