| titleOfInvention | Method for producing vinyl chloride monomer (VCM) and polyvinyl chloride (PVC) by purifying ethylene dichloride (EDC) |
| abstract | Disclosed herein is a method for purifying an EDC stream, the method comprising the steps of: ultimately removing low boiling impurities from the EDC stream to produce an EDC stream substantially free of low boiling impurities; flowing the EDC into Feeding into a heavy fraction distillation column to obtain a substantially pure EDC overhead stream and a bottoms stream comprising high boiling impurities having a low EDC content, the heavy fraction distillation column comprising an upper portion and a lower portion, which may or may be combined It may be in two separate sections (columns) but in a gas phase and a liquid phase communication between them, and has an intermediate reboiler at the bottom of the upper column. |
