Plate heat exchanger for oil refining and chemical industry has been widely used in petrochemical and refinery heat exchange system, its structure is strong, high reliability, strong applicability and other advantages have been in the petrochemical and refinery production and use of the dominant position.
In 1990 Lanzhou refinery additives workshop to solve the problem of corrosion of heat exchange equipment containing hydrochloric acid low polymer media, with a refinery chemical special plate heat exchanger instead of the original system of floating head type carbon steel shell and tube heat exchanger.
After installation can be used to carry out a development phase, found in the carbon steel receiver at the corrosion, while the equipment enterprise internal titanium plate plate without corrosion phenomenon, the receiver will be changed to titanium receiver, after running so far, corrosion has not occurred, completely unable to meet the company's production technology process design requirements. The results show that the equipment completely solves the corrosion problem, heat transfer area of the original equipment 1/4, covers an area of only about 20% of the original equipment. And more importantly, it prolongs the production cycle and avoids the economic loss caused by the equipment maintenance stoppage.
We hope that through the above introduction, you have more understanding of the chemical special plate heat exchanger, and will help you in your future work, if you need to contact us, we look forward to serving you.
