Petrochemical industry: Corrosion condition of gasoline cooler tube bundles
Thread Content
Corrosion in petrochemical heat exchangers hinders the safe operation of production facilities. The image above shows the sample tube used for the physical and chemical testing of the tube bundle in the atmospheric and vacuum gasoline water cooler. Circulating water (30-40 degrees Celsius) flows inside the pipes, while gasoline (90-130 degrees Celsius) flows outside them. Due to the severe corrosion of carbon steel tube bundles by water and gasoline, heat exchangers often experience leaks that lead to shutdowns. The image below shows the corrosion on the metal surface of the heat exchange tube (diameter 25*2.5 mm) after less than 1 year of use.
In the petrochemical industry, the safe operation of heat exchangers is constrained by corrosion. The sample tube shown is the tube bundle of a atmospheric and vacuum gasoline water cooler; circulating water at a temperature of 30–40 degrees flows inside the tubes, while gasoline at a temperature of 90–130 degrees flows outside them. Due to the strong corrosive effect of water and gasoline on carbon steel tube bundles, it often leads to leaks in the heat exchangers and subsequent shutdowns. The image shown is a heat exchange tube with a diameter of 25*2.5 mm; within less than a year of use, severe corrosion occurred on its metal surface. .
Does naphthenic acid cause corrosion? What are the serious consequences of such corrosion?
If it is caused by water corrosion, our microwave scale prevention and removal equipment can solve the problem. But what is used outside is gasoline, which is flammable and explosive; therefore, our equipment cannot use it. If the medium is not flammable or explosive, we can do it.
