ABSTRACT

Hydrate formation is a major issue with flow assurance in the oil and gas business. Hydrates compounds are crystalline and non-stoichiometric substances that form when gas and water are combined at high pressure and low temperature. Hydrates accumulating along flow line could cause restrictions to flow. In order to conduct a constant volume experiment in this work, three kinetic hydrate inhibitors—Vinisil, Rubber Latex, and Methacrylate Ester with Dimethyl aminoethyl—are utilized in a laboratory flow loop at 150 psi for two hours. The laboratory flow loop of 12 meters is built from 316 stainless lengths of steel with an internal diameter of 0.5 inches. Coolant is contained in a 4-inch Polyvinyl Chloride (PVC) conduit that encircles the steel pipe. The loop's goal is to look at how hydrate production and inhibition work. Three indicators to indicate that hydrate formation is taking place in the loop are a rise in the loop temperature, a rise in the differential pressure, and a decline in the loop pressure. It was discovered that 0.05 weight percent Rubber Latex and 0.05 weight percent Vinisil effectively inhibited hydrate formation in the loop. In terms of inhibiting hydrate formation, 0.05 weight percent Methacrylate Ester with Dimethyl aminoethyl performed poorly, as shown by the laboratory flow loop. This research succeeded in deriving mathematical models that reflected the behaviors of these inhibitors within the laboratory flow loop. The experiment reported in this article can be used to screen hydration inhibitors prior to field application.
