提高丙烯和混合碳四产品收率的对策与措施

中国石油化工股份有限公司茂名分公司化工事业部乙烯装置随着运行周期的延长，高低压脱丙烷塔和脱丁烷塔结垢严重，分离效果变差，造成丙烯和混合碳四产品的收率降低。通过分析丙烯和混合碳四产品损失大、收率低的原因，提出对策并采取相应措施，从而有效地提高了丙烯和混合碳四产品的收率。

Measures for Improving the Yields of Propylene and Mixed C4 Products

The long-term operation and worse separa- tion effect of HP/LP Depropanizer and Debutanizer, which is due to serious fouling,leads to the low yields of propylene and mixed C_4.Reasons for the low yields of propylene and mixed C_4 are analyzed and countermea- sures are put forward,thus the yields of propylene and mixed C_4 are effectively improved.
