摘要：

依托某环氧乙烷/乙二醇（EO/EG）装置转产改造项目，首次实现通过新增串联的环氧乙烷（EO）精制系统，使乙二醇（MEG）生产占比降低至反应器当量环氧乙烷（EOE）能力的20％以下，其余全部生产精制环氧乙烷产品，实现乙二醇转产环氧乙烷。新增EO精制塔采用新型复合筛板以满足扩能需求，采用优化的加热控制系统适应更宽的进料组成，并开发了集成的排醛系统以控制新增EO精制塔产品中的醛含量。

Abstract:

Based on the conversion and retrofitting project of a certain ethylene oxide/ ethylene glycol (EO/EG) unit, over 80% of the reactor's ethylene oxide equivalent (EOE) capacity was utilized to produce purified ethylene oxide (PEO) for the first time by adding an EO purification system operated in series, thereby converting ethylene glycol production to ethylene oxide production. The new EO purification tower employs novel composite sieve plates to meet the capacity expansion requirements. An optimized heating control system was used to accommodate broader feed compositions, while an integrated aldehyde removal system was developed to control the aldehyde content in the product of the new EO purification tower.

Key words: PEO, EO purification, aldehyde removal, heating control, composite sieve plate
