Seeking advice on distillation column issues
Thread Content
Currently, the process uses negative pressure along with steam bubbling to raise the temperature to 130°C in order to remove epichlorohydrin (whose boiling point is 110°C). The introduction of steam introduces moisture, which can still affect the hydrolysis of epichlorohydrin. If internal coil steam heating is used along with nitrogen stripping, it would essentially function as a batch-type nitrogen stripping unit. It’s just not clear whether nitrogen stripping can achieve the same results as negative pressure distillation; it’s possible that epichlorohydrin may not be removed completely
You can ask someone who is familiar with chemical engineering software to help you simulate the operating conditions and see what the results of the simulation are.
