The effect of lithium bromide on corrosion of metals

The concentration of LiBr in solution can significantly affect the rate and severity of corrosion in metals. The concentration of lithium bromide can increase the corrosion rate, affect the pH of the solution, the formation of corrosion products, the solubility of oxygen, the effects of temperature, and also cause specific metal reactions.

Dealing with corrosion in the well with corrosion inhibitors

Downhole corrosion is one of the most important problems facing the oil and gas industry. By using various methods such as selecting appropriate materials, surface coating, use of corrosion inhibitors and cathodic protection, the corrosion rate can be significantly reduced. A better understanding of corrosion mechanisms and the development of new technologies can help improve efficiency and reduce costs in this industry.

Classification of corrosion inhibitors according to mechanism and composition

Corrosion inhibitors are substances that, when added in small amounts to a corrosive environment, slow down the rate of corrosion. In fact, an inhibitor can be considered a retarding catalyst. There are many inhibitors available with different compositions.

Corrosion inhibitors

Corrosion inhibitors are additives that control corrosion by altering the metal surface, the environment, or both. Their mode of action is to alter the anodic, cathodic, or both reactions. There are many corrosion inhibitors available with different compositions. Most of these materials have been discovered and refined through experimental testing, and many of them are sold under trade names and their chemical composition is kept secret.

Investigating the phenomenon of corrosion in the cooling tower and its control

Corrosion is one of the most important problems in the cooling tower and causes cost loss and reduced efficiency of the tower. The presence of various factors in the tower makes it easy for corrosion to occur in the cooling tower. The presence of water as an electrolyte and also the presence of metals of different types in the tower as cathode and anode provides the basis for creating a chemical cell on a large scale.

Corrosion in boilers

Corrosion in steam boilers is caused by chemical and electrochemical reactions of metal with its surrounding environment. The most important corrosion factors in steam boilers are oxygen corrosion, carbon dioxide corrosion, corrosion due to pH drop, alkalinity corrosion, corrosion of hydrolyzable salts and corrosion of organic materials.

Ways to prevent corrosion

Any process that delays corrosion is called corrosion inhibition (prevention of corrosion). In general, corrosion inhibition means reducing the rate of oxidation of a metal or adding a chemical compound that will be in contact with the solution in the system. The corrosion inhibitor may be added in liquid, vapor, or both. Specifically, a corrosion inhibitor is a chemical compound that is added to the liquid phase in such a way that it affects the metal surface.

Corrosion engineering (damages and costs due to corrosion)

Investing in corrosion control is a form of profitability. Ignoring corrosion problems in any industrial and manufacturing unit leads to hidden costs that are impossible to avoid. The first step in corrosion economics is to choose an appropriate method to minimize corrosion costs. These costs can include: production and equipment costs, loss of valuable products, undesirable product appearance, environmental costs, and so on.

Various methods of removing water oxygen from the boiler

Boiler systems encounter two gases, oxygen and carbon dioxide, dissolved in the water entering them during their working process. The presence of these gases causes corrosion in boilers and heating systems and will disable the device in the long term. Usually, dissolved oxygen in water is removed in two ways, physically and chemically.

Oxygen scavengers

Oxygen scavengers, oxygen scavengers, oxygen absorbers, anti-oxygen or (oxygen scavenger) are used to remove oxygen in various industries. The oxygen scavenger reacts with dissolved oxygen and prevents the reduction of oxygen to hydroxide ions, thus acting as a corrosion inhibitor.
