Development and Performance Evaluation of Natural Gas Drag Reducer
The main agent of 1,4-benzoate docosanide(BADD)was prepared by esterification of terephthalic acid with methanol and amidation with linear amine.Anhydrous ethanol/N-methylpyrrolidone was selected as solvent,1%MONENG-7008 leveling agent and 1%JSC-1150 adhesion promoter were selected as additives.The properties of natural gas drag reducer 1,4-phthalate docosanide were evaluated by using corrosion inhibition rate and drag reduction effect as evaluation indexes.The results show that when the concentration of BADD is 5 g/L,the corrosion inhibition efficiency reaches 85.8%and the drag reduction rate reaches 13.7%.
