Abstract

FIELD: petroleum refining industry, petrochemical industry, determination of effectiveness of anticorrosion protection of industrial plants of primary oil refining. SUBSTANCE: method establishing inhibiting efficiency of hydrocarbon-solved corrosion inhibitor under conditions of primary refining of oil includes determination of coefficient (γ) of deceleration of corrosion of carbon steel in laboratory by gravimetric process. " Barrier " coefficient (γb) and degree (θ), of electrode filling are found in advance and are used for evaluation of adsorption capability of inhibitor with subsequent determination of coefficient of deceleration of cathode (γc) and anode (γa) reactions from which relation (lg, γa/γc) corrosion-electrochemical efficiency of inhibitor is estimated. Efficiency of inhibitor is found with coefficient γ of deceleration of steel above 10, concentration of inhibitor under 100 ppm, on basis of relationship γ: γb: θ: lg γa/γc which with γb/γ not less than 0.8, amounts to 1: (0.02-0.07):(0.02-0.2). In this case γ is taken as datum value and all other values correspond to it. EFFECT: raised authenticity and speed of establishment of inhibiting capability of substance under conditions of primary refining of oil. 1 tbl
