Abstract
The present disclosure generally relates to antifoulant compositions and methods of preventing or inhibiting fouling. The disclosure relates to antifoulant compositions comprising one or more solvents, one or more antipolymerants, and one or more dispersants. The compositions may include other optional components, such as an antioxidant, an alcohol, and/or water. Methods of using the compositions in natural gas dehydrogenation processes to prevent or minimize fouling are also disclosed.
Claims20
A method of inhibiting fouling in a natural gas dehydrogenation process, comprising:
- adding an antifoulant composition to a medium in the natural gas dehydrogenation process, wherein the antifoulant composition comprises a solvent, an antipolymerant, and a dispersant.
An antifoulant composition, comprising:
- a solvent, an antipolymerant, and a dispersant, wherein the solvent is selected from the group consisting of a carboxylic acid ester solvent, a cyclic ester, a phthalic acid ester, a lactone, a hydroxy carboxylate ester, an ester of a cyclohexane dicarboxylic acid, an ester of a cyclopentane dicarboxylic acid, a lactam, N-pyrolidone, a glycol, and any combination thereof.
