Abstract
A method of reducing or inhibiting fouling deposit formation from liquid hydrocarbons within an anaerobic environment. The method includes a liquid hydrocarbon and an antifouling composition combined to reduce or inhibit deposits when the liquid hydrocarbon is heated to temperatures of about 100° C. or greater in an anaerobic environment. The antifouling composition includes one or more linear or branched alkali or alkaline earth metal salts and/or one or more nitrogen-containing alkenyl succinimides.
Claims19
A method of reducing or inhibiting fouling deposit formation from liquid hydrocarbons within an anaerobic environment, the method comprising combining a liquid hydrocarbon and an antifouling composition to reduce or inhibit deposits when the liquid hydrocarbon is heated to temperatures of about 100° C. or greater in an anaerobic environment and wherein the antifouling composition includes (a) one or more linear or branched alkali or alkaline earth metal salts, (b) one or more nitrogen-containing alkenyl succinimides, or combinations of (a) and (b).
An antifouling composition suitable for use with liquid hydrocarbons, the antifouling composition comprising:
- (a) one or more linear or branched alkali or alkaline earth metal salts;
- and/or (b) one or more nitrogen-containing alkenyl succinimides;
- and (c) optionally one or more phosphorus containing compounds.
