Adsorption and desorption of a product is an important factor in the assessment of availability requirements for a corrosion inhibitor in a given system. Corrosion inhibitors that have film persistence can allow the safe operation of a corrosive oil and gas system for some time period when corrosion inhibitor injection is interrupted. Successful batch corrosion inhibition occurs when significant corrosion inhibition occurs when a corrosion inhibitor is not present in the bulk phase. This paper describes corrosion inhibitor tests that were carried out at different temperatures and interpreted using Langmuir adsorption and desorption. Studying corrosion inhibitor performance and fitting the behavior with Langmuir adsorption and desorption enables a better determination of safe operating envelopes of a system when corrosion inhibitor injection is interrupted. The tests aid the development of an improved assessment of availability of corrosion inhibitor

Key words: Corrosion Inhibition, Batch Treatment, CO2 Corrosion, Corrosion Inhibitor Availability, Adsorption, Desorption, Health Monitoring, CBM
