PET装置酯化蒸气节能优化措施

Energy saving optimization measures of esterification steam in PET plant

通过对酯化蒸气热量分析,结合装置实际工况,提出酯化蒸气在冬季供暖、夏季提供冷冻水、浆料升温、乙二醇升温、取代蒸汽加热等较为实用的节能措施。降低生产能耗,从而创造经济效益。

Through the analysis of the heat of esterification steam, combination with actual working conditions of PET plant, the more practical energy-saving measures such as heating the esterification steam in winter, supply cooling water in summer, slurry heating up, ethylene glycol heating up, instead of steam heating were put forward. Energy consumption was reduced, thereby creating economic benefits.
