The restructured branch will bring products to market, increasing the flow of returns
Increasing the flow rate will raise the load on the reflux tower; more vapor will be present in the tower top, and the tower pressure will also increase. This could lead to a vicious cycle, and the equipment may not be able to handle it. I’m not sure if my understanding is correct Seeking corrections from fellow netizens
It is more convenient to operate and consumes less energy, but an adequate supply of circulating cooling water is necessary.
My personal understanding is that the ambient temperature has little impact on the performance of a distillation tower, as the temperature within the tower remains relatively constant since the composition of the components in it doesn’t change. The only difference lies in the temperature of the cooling medium used in the top condenser (such as CW/RW); if this temperature changes, it is necessary to increase the flow rate to maintain an effective cooling effect and the appropriate reflux temperature. I’m not sure if my understanding is correct; please correct me!
If permitted, the tower pressure can be increased slightly, the condensation temperature difference at the top of the tower can be raised, thereby saving water.
In summer, as the temperature of the circulating water rises, the system temperature increases as well, leading to an increase in the feed temperature, particularly that of the gas phase feed. This results in heavier components moving upward, necessitating an increased reflux rate.
Just keep the temperature and pressure under control.
It should be that way, but right now the top of the tower won’t cool down!
