Evaluation on the Effects of Wax Inhibitor and Optimization of Operating Parameters For Wax Deposition in Malaysian Crude Oil

The complex phenomenon of wax deposition subject to thermal gradient in crude oil is one of the biggest challenges in petroleum industry. In this comparative study, two inhibitors which were poly(ethylene-co-vinyl acetate) (EVA) and xylene were investigated in terms of rate of wax deposition in Mala...
