Alkylphosphonate ester compounds or acids thereof are disclosed as effective fouling inhibitors in liquid hydrocarbonaceous medium undergoing processing at elevated temperatures.

Crude oil composition comprising an alkylphosphonate antifouling additive

Methods for inhibiting fouling in hydrocarbons

Methods and compositions are provided for cleaning and inhibiting the formation of fouling deposits on jet engine components during the combustion of turbine combustion fuel oils. Methods and compositions are also provided for inhibiting the formation and emission of soot and smoke from jet engine exhaust during turbine combustion fuel oil combustion. The methods employ a derivative of (thio)phosphonic acid added to the turbine combustion fuel oil. The preferred derivative is pentaerythritol ester of polyisobutenylthiophosphonic acid.

Methods and compositions for reducing fouling deposit formation in jet

A contaminant precipitating composition and method are disclosed. The composition comprises a water soluble branched polymeric composition effective for the purpose of precipitating contaminants from an aqueous solution. The method comprises adding an amount of the composition, effective for the purpose, to the aqueous solution so as to complex, precipitate and remove contaminants from the aqueous solution.
