[0002] In vinyl chloride production, the hot water tank of the conversion system, the regeneration heater of the monomer dehydration system, and the desorption tower heater of the hydrochloric acid desorption system are all heated by steam to reach the temperature required for production. During the use of steam, condensate will be generated in the steam main. The temperature of the steam condensate is too high to be directly reused and is discharged through the steam trap. Due to the large amount of steam used, a large amount of condensate is generated, and the discharge causes waste. Utility Model Content
