摘要： 介绍了某炼油企业低温热利用节能改造的情况。利用催化装置产生的低温热源加热热媒水，为气分装置提供塔底重沸器热源，取代了原来的蒸汽加热。通过能量的梯级利用，有效解决了全厂热源能级利用不合理的现象。项目投用后，节能效果显著，经济效益可观。具有较好的推广价值。

Abstract: Optimizing the utilization of low temperature heat (LTH) in a refinery was introduced, such as using LTH from FCC unit instead of steam to heat up water as heat source for the re-boiler of gas separator and etc. Through utilizing heat by grading, the energy consumption and heat recovery in the whole refinery were optimized, and significant economic benefit was obtained, e.g. 139.2 GJ/h heat was withdrawn from FCC unit and 34.1 t/h steam was saved at gas separation device.
Key words: energy consumption, low temperature heat, heat carrier, energy conservation, modernization
