摘要：

近年来，随着国家对环保监管力度的加大，各企业对乙烯装置低排放日益重视，乙烯装置的开停车过程中，在保证人员、装置及设备安全的基础上，优化开车步骤，缩短开停车时间，减少开停车过车中的物料损失，是乙烯装置追求的目标，多年来各企业已近积累了丰富的经验。而乙烯深冷分离是乙烯装置开停车过程中物料损失的大户，独山子石化220 kt/a乙烯分离开停车在原有措施的基础上对系统降温速度慢、物料损失大等问题进行了新的研究分析，通过有针对性技改技措的实施，大幅缩短了开车时间，减少了开停车过车中的物料损失。

Abstract:

In recent years, with the strengthening of national regulation on environmental protection, enterprises pay more and more attention to the low emission of ethylene plant. During the startup and shutdown of ethylene plant, optimizing startup steps, shortening startup and shutdown time and reducing material loss during startup and shutdown while ensuring the safety of personnel, plant and equipment are the goals of ethylene plant, and over the years, various enterprises have accumulated rich experience. The ethylene cryogenic separation unit has the highest material loss during the startup and shutdown of ethylene plant. Based on the original optimization measures, the 220 kt/a ethylene separation unit of Dushanzi Petrochemical conducted new researches and analysis on the problems including low cooling speed and high material loss of the system. Through the implementation of targeted technical transformation measures, the startup time was greatly shortened and the material loss during startup and shutdown was reduced.

Key words: ethylene separation, startup and shutdown, material recovery, low emission
