A THERMODINAMIC CORROSION STUDY OF CARBON STEELS IN HYDROGEN SULFIDE - EXPLORING CHEMICAL EQUILIBRIUM CONCEPTS

This study addresses an inherent problem to the oil and natural gas exploration and production industry, the corrosion of pipes and tanks by H2S. H2S with water emulsified in the oil or H2S with the water vapor mixed in the gas, they make the acid environment leading to corrosion. This is commonly m...
