【Q&A Question 252】September 15, 2018: Why is it necessary to add a corrosion inhibitor to the top of the stripping tower? Since the gas at the top of the stripper is highly saturated with hydrogen sulfide and is at low temperature, it forms an H2S-H2O type corrosion with water vapor, resulting in particularly severe corrosion. The addition of a corrosion inhibitor forms a protective film, which reduces the corrosion caused by hydrogen sulfide on the top of the stripping tower and the heat exchange system, thereby enabling the equipment to operate for extended periods of time. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

Because the gas at the top of the stripping tower has a high hydrogen sulfide content
Since the gas at the top of the stripping tower contains high levels of hydrogen sulfide and is at low temperature, it forms H2S-H2O type corrosion with water vapor, resulting in particularly severe corrosion
Corrosion inhibitors are used to reduce corrosion in the tower top cooling system.

The gas at the top of the stripping tower contains high levels of hydrogen sulfide and is at low temperatures, which leads to H2S-H2O type corrosion in combination with water vapor, resulting in particularly severe corrosion. The addition of a corrosion inhibitor forms a protective film, which reduces the corrosion caused by hydrogen sulfide on the top of the stripping tower and the heat exchange system, thereby enabling the equipment to operate for extended periods of time.

The gas overhead product has a high sulfur content and concentration, making it one of the areas most susceptible to corrosion.
