CORROSION INHIBITION OF WET GAS PIPELINES UNDER HIGH GAS AND LIQUID VELOCITIES

摘要: Work was conducted to assess the applicability of carbon steel pipeline and corrosion inhibitor as a viable combination for transporting wet multiphase corrosive petroleum fluids under high gas liquid velocities. Flow loop tests were performed study performance inhibitors simulated field conditions with velocity 25 rn/s. The results showed that inhibition efficiency greater than 96% can be achieved 100 200 ppm specially formulated shear applications. respect concentration typical profile similar observed at lower velocity. effective dependent upon flow regime. Slug typically required higher due its severe flowing condition. positive support combined use cost-effective option development system transportation hydrocarbon
