Is air cooling or a heat exchanger used at the top of the atmospheric and vacuum distillation tower? I would like to change it to a heat exchanger; please provide recommendations
Check the location and the local water resources situation!
Do you want to use a heat-recovery type of heat exchanger? You can get in touch to communicate
Heat exchangers and air cooling can be used; if only a heat exchanger is used, then the recovered heat can be calculated accordingly. Preventing high temperatures is difficult to control
Generally, heat exchange is combined with air cooling, while water cooling is considered for the final stage
It would be more economical to use a heat exchanger to recover heat from the higher temperature at the front door
Considering its reasonable economic viability, it cannot be generalized; a case-by-case analysis is required. Generally, an air cooler is used first, followed by a heat exchanger.
The temperature at the top of the tower is relatively high; it first exchanges heat with crude oil to recover thermal energy. If the temperature remains high, it is then sent to air cooling to prevent scaling due to high-temperature water entering the cooling system. After air cooling, the fluid goes through water cooling again to reach the desired temperature.
First exchange heat with crude oil, then air-cool, and finally water-cool
