环丁砜抽提装置是芳烃生产的重要环节之一,操作中经常会遇到汽提塔发泡的生产难题。本文以辽阳石化公司芳烃抽提装置为例,首先对汽提塔发泡现象进行了简单描述,其次对各方面因素进行了分析与总结,并从控制原料组成、改善操作方法、工艺参数、提高溶剂质量及设备等方面提出了防止发泡的相关措施,不仅使发泡现象得到了有效缓解,还能使装置平稳运行保证产品质量和收率,从而提高生产效率,降低生产成本。
Sulfolane extraction unit is an important part of the production of aromatic hydrocarbons, often encountered in the operation of stripping tower foam production problems. In this paper, aromatics extraction unit of Liaoyang Petrochemical Company is taken as an example. First, the foaming phenomenon in the stripper is briefly described. Secondly, various factors are analyzed and summarized. From the aspects of controlling the composition of raw materials, improving the operation method and process parameters, Solvent quality and equipment and other aspects of the proposed measures to prevent foam, not only to foam the phenomenon has been effectively alleviated, but also to make the device run smoothly to ensure product quality and yield, thereby increasing production efficiency and reduce production costs.
