Heat exchanger coking and treatment methods
Thread Content
In the petrochemical production process, some heat exchangers tend to form scale after operating for a certain period of time, which severely affects the heat exchange efficiency and the service life of the tube bundles. The normal operating conditions are 200–300 degrees, a pressure of 1–2 MPa, with the medium being petroleum slurry or residue. It is recommended to use high-pressure water jet technology and chemical cleaning technology for treatment.
Coking in heat exchangers is mainly caused by high temperatures and the heavy components in petroleum fluids. Treatment methods include using high-pressure water jet technology to flush carbon deposits inside the pipes, as well as employing chemical cleaners to dissolve residual coke. These two methods can effectively restore the heat transfer efficiency of heat exchangers and extend their service life. .
