Severe coking in the heat exchangers for petrochemical residue oil
Thread Content
In the petrochemical production process, some residue oil heat exchangers tend to clog 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. For such coked heat exchanger tubes, high-pressure water jet technology or chemical cleaning methods can be employed to remove the fouling, thereby improving the heat transfer efficiency and service life of the heat exchanger.
Coking in the residue oil heat exchanger can be addressed using high-pressure water jets or chemical cleaning methods, thereby improving heat exchange efficiency and extending its service life. .
