Inhibering av asfalten-avleiring i produksjonssystemer for råolje

摘要

It has been discovered that various ester and ether reaction products are excellent asphaltene deposition inhibitors or dispersants for use in hydrocarbons such as crude oils. The asphaltene inhibiting compounds may be (1) esters formed from the reaction of polyhydric alcohols with carboxylic acids; (2) ethers formed from the reaction of glycidyl ethers or epoxides with polyhydric alcohols; and (3) esters formed from the reaction of glycidyl ethers or epoxides with carboxylic acids.
