[Help] Regarding the rich-lean oil heat exchanger
Thread Content
Xiaobai is asking for help: in a hot and cold oil heat exchanger, does the hot oil flow through the tube side or the shell side?

@Moderator, please cover the company name and design in the attachment I sent. Thank you!
By switching to a plate type, there is no longer a distinction between plates and tubes
1. In heat exchangers or heaters, the heating medium generally flows through the tube side, while the medium to be heated flows through the shell side, which results in high thermal efficiency； 2. If the medium is high-temperature, flammable, explosive, toxic, harmful, or highly corrosive, it must be handled in the tube side; in the event of a leak, the substance can only escape into the shell side, preventing any direct harm from occurring ； In summary, hot lean oil should flow in the tube side.
There are several common guidelines regarding the layout of heat exchangers. Generally, the hot fluid flows through the tube side, which helps to reduce heat loss. Fluids that are toxic, harmful, or highly corrosive are also sent through the tube side to prevent potential leaks from causing serious problems. The temperature of the cold oil as well as various impurities tend to be handled on the tube side as well; however, these are just general rules, and the actual layout should be determined by considering various factors based on the specific circumstances.
