FORMULATION OF POLYMERIC INHIBITOR FOR VISCOSITY REDUCTION OF CRUDE OIL
Abstract – Generally, waxes and asphaltenes classified as solid category which involved with deposition of high-molecular-weighted compounds along pipelines which leads to production issues. In this study the effect of different mixture concentration consisting of copolymer and solvent on crude oil viscosity in order to find a solution for reduction of wax and asphalthene deposition along the surface of pipelines. There were two proportions used which consist of EVA 25, MCH and paraxylene as first proportion and EVA 40, MCH and paraxylene as second proportion. The objective of this study was to formulate a mixture of EVA, MCH and paraxylene at different ratios and tested for flow properties improvement of crude oil viscosity. Laboratory experiments were designed by response surface methodology (RSM) specifically central composite design (CCD) to formulate ratios, and analyzed for optimum percentage composition of mixture to obtain a good model. The optimum parameters were found from the CCD, 10.02% of EVA 25, 10% of MCH and 79.987% of paraxylene for first proportion and 10% of EVA 40, 45.78% of MCH and 44.22% of paraxylene for second proportion to minimize the viscosity of crude oil.
