摘要：

针对裂解原料轻质化造成夏季三元制冷系统制冷能力不足以及轻烃原料汽化过程能耗高的问题，利用流程模拟软件Aspen Hysys，分别对轻烃原料汽化过程中供冷能和三元制冷系统降温过程中耗能情况进行局部建模计算，表明轻烃原料的汽化供冷能可满足三元制冷系统冷能需求。通过技改解决了夏季生产瓶颈问题，同时也节约了能耗、降低了乙烯损失，经济效益显著。

Abstract:

This paper discusses the insufficient refrigeration capacity of ternary refrigeration compressor in summer caused by light cracking raw materials and the high energy consumption during LPG vaporization, and uses Aspen HYSYS to calculate the amount of heat released by LPG vaporization and the energy consumption during the cooling of ternary refrigeration system. The results show that the amount of heat released by LPG vaporization can meet the demand of ternary refrigeration system. Through technological transformation, the production bottlenecks in summer can be solved, and the energy consumption and ethylene loss can be reduced, achieving significant economic benefit.

Key words: LPG, cold energy, ternary refrigeration, cold energy optimization
