ABSTRACT:

Stainless steel is a very important metal for petroleum industries. Petroleum industries use bulk amount of stainless steel for their several operational units. For the recovery of crude oil strong acid and high temperature is maintained which make environment highly corrosive. Due to corrosive environment electrochemical reaction takes place on the metal surface which starts corroding the metal. For this work organic inhibitors are used like propargylbenzenesulphonate and o-hydroxyl-propargylbenzenesulphonate in 20% H2SO4 at different concentrations and temperatures. The corrosion rate and percentage efficiency of inhibitors are calculated by gravimetric (Weight loss experiment) and potentiostatic polarization technique at 1mM, 5mM and 10mM concentrations of propargyl-benzenesulphonate and o-hydroxyl-propargylbenzenesulphonate at 30, 40, 50, 60 and 70?C temperatures.
