Analysis of acidic water in the device
Thread Content
Acidic water samples were taken from the device for analysis; one of the tests performed was for chlorides, with the analysis value being around 30 mg/l. What is the purpose of analyzing this? Please share your thoughts, thank you
Primarily for the selection of materials for equipment and pipelines
It’s mainly the material of the equipment; chloride ions cause corrosion to stainless steel
Acidic water generally refers to water used in the petroleum refining and chemical industry to absorb acidic gases such as hydrogen sulfide and carbon dioxide from reactants or products using an alkaline water solvent; hence it is called acidic water. In reality, it is a weakly alkaline water in which components such as sulfur compounds and carbon dioxide are dissolved. Acidic water normally contains low levels of chlorine, but as more and more containers and pipelines are made of stainless steel, monitoring of chloride ions has become more stringent. The monitoring of chloride ions in acidic water is primarily aimed at determining whether acidity exhibits corrosive properties.
Elevated chloride levels cause severe corrosion of stainless steel pipes, and can easily lead to corrosion and perforation of pipelines and equipment.
The higher the chlorine content, the greater the corrosive effect on pipe fittings, leading to more problems such as leaks.
