Abstract
An improved process for inhibiting the formation and deposition of polymer-based fouling materials after caustic scrubbing of hydrocarbon streams contaminated with oxygenated compounds with a basic washing solution having a pH>7 comprising adding to the hydrocarbon stream after caustic scrubbing a sufficient amount for inhibiting formation and deposition of polymer-based fouling materials of a composition comprising at least one hydrazide compound characterized by the formula ##STR1## where R is selected from the group consisting of H, NHNH.sub.2, and ##STR2##
Claims19
A method of inhibiting formation of polymeric fouling deposits after the caustic scrubbing of a hydrocarbon stream contaminated with oxygenated compounds with a basic washing solution having a pH>7 comprising adding to said hydrocarbon stream a sufficient amount for inhibiting formation and deposition of fouling materials of a composition comprising at least one hydrazide compound characterized by the formula ##STR7## where R is selected from the group consisting of H, NHNH.sub.2, and ##STR8##
A method of inhibiting the formation and deposition of fouling materials on the structural parts of hydrocarbon cracking equipment after caustic scrubbing with a basic washing solution having a pH>7 of a pyrolytically produced olefin contaminated with at least one carbonyl compound comprising adding to said olefin stream after said caustic scrubbing a sufficient amount for inhibiting formation and deposition of fouling materials of a composition comprising at least one hydrazide compound characterized by the formula ##STR9## where R is selected from the group consisting of H, NHNH.sub.2, and ##STR10##
