Management of corrosion caused by H2S gas in oil and gas industries
Corrosion in the Oil and Gas Industry
Corrosion in various industries, including the oil and gas industry, imposes heavy costs every year for the replacement or repair of equipment and machinery. Annually, 5 percent of the gross national product of countries is wasted due to corrosion, of which about one-fifth occurs in the oil, gas and petrochemical industries.
One type of corrosion in the oil and gas industry is corrosion caused by hydrogen sulfide gas. Many oil and gas facilities are made of carbon steel and are sensitive to corrosion by hydrogen sulfide gas. Hydrogen sulfide causes various types of corrosion in these steels.
Statistics show that about 74 percent of the failures of oil, gas and petrochemical facilities were due to sulfide cracking (Figure below). Therefore, the management of corrosion caused by hydrogen sulfide is of particular importance.
Special Products for the Oil, Gas and Petrochemical Industries
Hydrogen sulfide may be present in oil and gas reservoirs from the very beginning of production or may be produced by bacterial activities (anaerobic bacteria) during operation. In the downstream sector, hydrogen sulfide may also be produced during processing or storage.
Corrosion Management Framework in the Oil and Gas Industries
To successfully manage corrosion, a predetermined implementation framework must be implemented. Implementing effective corrosion management in the oil and gas industries will include the following results:
- It will meet safety, health and environmental objectives.
- Safety and environmental damage caused by leaks and failures will be minimized.
- It will increase the efficiency of the facility.
- It will lead to a reduction in production and maintenance costs.
- It will improve working conditions.

Effect of chlorine ions on stainless steels
The effect of chlorine and chloride parameters on the corrosion of stainless steels and the parameters affecting their corrosion rate, as well as the acceptable limits of chlorine ion levels in water and the differences in the effects of free chlorine and chloride on the corrosion of corrosion-resistant steels, are stated.
Caustic corrosion
Localized corrosion caused by the concentration of caustic or alkaline salts, which usually occurs under conditions of high evaporation or heat transfer. Caustic salt or caustic soda is one of the most widely used ionic compounds and is used in various industries including water treatment, cardboard and paper production, oil and refinery industries, aluminum production industries, food industries, alcohol production and glass.
Corrosion and deposition of cooling water based on API 571
It refers to general or localized corrosion of carbon steels and other metals caused by dissolved salts, gases, organic compounds, or microbiological activity.
Microbial corrosion based on API 571
Microbial corrosion is a type of corrosion caused by living organisms such as bacteria, algae, or fungi. This type of corrosion is often associated with tubercles or slimy organic materials.
Corrosion process in different environments
Corrosion processes are divided into three groups in a more comprehensive classification: corrosion in aqueous solutions or environments, corrosion in molten salts and liquid metals, and corrosion in gases.
Oil-soluble corrosion inhibitor for the protection of oil transfer and storage equipment
Corrosion is a natural phenomenon that occurs as a result of the electrochemical reaction of metal with the surrounding environment. In the oil and gas industry, corrosion is one of the major problems that accounts for a huge amount of money annually. Part of these amounts are related to the corrosion of pipes or oil transmission lines. Effective ways to prevent corrosion of oil transmission and storage equipment are divided into two categories: physical and chemical solutions.
couponing
The coupon method or corrosion coupons is the simplest method of corrosion monitoring. Coupons are the oldest corrosion monitoring tool. Corrosion coupons are small pieces of metal or alloy of the material of interest that are immersed in the process medium and removed after a specified period of time and their weight or dimension loss is evaluated and examined.
Deaerators
Deaerators are mechanical devices that remove dissolved gases from the boiler feedwater. By reducing the concentration of oxygen and carbon dioxide in the solution, they minimize corrosion and protect the boiler from the effects of corrosive gases.
