Functionalized polymers containing polyamine succinimide for antifouling in hydrocarbon refining processes

摘要

A multipurpose chemical additives (MPC) is disclosed to mitigate fouling in hydrocarbon refinery processes, such as in a heat exchanger. A method for reducing fouling of a hydrocarbon is also disclosed that includes (i) providing a crude hydrocarbon for a refining process; and (ii) adding an additive to the crude hydrocarbon.

1. A method for reducing fouling in a hydrocarbon refining process comprising
providing a crude hydrocarbon for a refining process; and adding an additive to the crude hydrocarbon, the additive selected from the group consisting of: wherein: m is an integer between 0 and 10 inclusive; R1 is a branched or straight-chained C10-C800 alkyl or alkenyl group; R2 is a C1-C4 branched or straight chained alkylene group; R3 is a C1-C4 branched or straight chained alkylene group:, R31 is hydrogen or —R8—R9, wherein R8 is C1-C4 branched or straight chained alkylene group, and R9 is wherein R91 is a branched or straight-chained C10-C800 alkyl or alkenyl group; or R8 and R9 together are a C1-C4 branched or straight chained alkyl group optionally substituted with one or more amine groups; and further wherein the —N(R31)—R3— repeat unit is optionally interrupted in one or more places y a nitrogen-containing heterocyclic cycloalkyl group:, and R4 and R5 are each independently selected from (a) hydrogen; (b) a bond connected to R31 in the m-th —N(R31)—R3— repeat unit; or (c) —R6—R7, wherein R6 is C1-C4 branched or straight chained alkylene group, and R7 is wherein R71 is a branched or straight-chained C10-C800 alkyl or alkenyl group, wherein, n is an integer between 0 and 10 inclusive, and the groups R2′, R3′, R31′, R4′ and R5′ are each defined the same as R2, R3, R31 and R4, and R5, respectively, and wherein at least one of R1, R71, and R91 comprises polyethylene.
