Heat source for the reboiler at the bottom of the vapor phase propane removal tower
Thread Content
What medium is used as the heat source for the bottom reboiler of the propane removal column in the gas phase? 1. Steam at 1.0 MPa 2. Circulating oil from the distillation overhead of the catalytic unit 3. Other. What medium do you use? Feel free to discuss
It actually depends on the design of the device; it basically falls into the first two categories you mentioned. The use of catalyzed primary distillate gasoline is generally implemented in a heat well mode that ensures overall thermal balance in the plant, allowing for stepped utilization of thermal energy to maximize its efficient use!
Is there heat exchange with other device media within the company?
The top circulation and reflux effect using the catalytic device is very good.
Two reboilers are installed at the bottom of the tower; one uses catalytic top circulation while the other uses steam； During normal production, catalytic top circulation heating is sufficient; it allows for heat recovery and reduces waste. Moreover, since the temperature is not as high as that of steam, and the temperature and pressure fluctuations are minimal, the temperature is easier to control after heat exchange. In the event of abnormalities in distillation production, steam heat exchange is employed; the purpose is to prevent mutual interference with the distillation tower | ???ω??)???
The original design used LS and one reboiler; later, a thermal integration upgrade was carried out with the catalytic unit, utilizing top-loop oil as the heat source
What is the temperature at which your top loop oil is degassed, and what is the flow rate? Is it sufficient to meet the requirements?
