H2S – A Silent Ultimatum to Oilfields

H 2 S Scavenger Chemical – Introduction The world has witnessed a substantial increase in E&P of crude oil to meet the need for globalization, leading to drilling of ‘deemed undesirable’ sites, owing to the presence of higher concentration of acidic gases like hydrogen sulphide, carbon dioxide, etc. These hazardous gases require proper measures before disposal or scavenging. Of these, Hydrogen sulphide/ H 2 S is the most threatening one, especially in confined or ill ventilated places. The characteristic rotten egg smell makes H 2 S recognition easy even at lower concentrations. Hydrogen Sulphide is toxic, acidic and extremely corrosive at higher concentrations. Heavier than air, it is found more near base level of the working sites. Then comes its inflammability, which may cause explosive reaction with air molecules. With peroxides, ammonia and other oxidizing chemicals, H 2 S often goes through combustible reactions, ...

Acid Corrosion Inhibitor – Chemtex Speciality Limited

  Acid Corrosion Inhibitors are the most important inhibitor of any operation, preventing the impact of corrosion on exposed metal, tubular, downhole equipment, and surfaces and maximizing longevity, minimizing the operational cost. Corrosion is the chemical interaction with the environment that cause the deterioration of materials and it is unavoidable for all metals. When acids come into contact with metals, they initiate chemical reactions that lead to corrosion. Acid corrosion inhibitors work by forming a protective layer on the metal surface, which acts as a barrier against the corrosive acids. This layer prevents direct contact between the acid and the metal, thus inhibiting the corrosive process.
