What determines the temperature control of the distillation feed cooler?
Thread Content
Something strange happened at work: the temperature of the feed cooler in the distillation tower increased significantly when the refrigerant flow rate was increased. I don’t know the reason; the gauge is fine. What do we generally use as a basis to determine what appropriate value this temperature indicator should have? Also, the main function of this cooler is to regulate the feed temperature, right? It controls the state of the feed – does it also have the role of removing moisture?
Feed coolers are generally used to control the feed temperature, with the aim of ensuring that the feed conditions remain within the design parameters of the distillation column. The specific control amount should be determined with reference to the indicators on the distillation column process card. However, increasing the amount of cold sulfur in the cooler does not raise the temperature of the feed cooler to the distillation tower; an increase may be caused by other factors, such as changes in the temperature or composition of the material fed into the cooler. Each case needs to be analyzed on its own.
