摘要/Abstract

摘要：

以某乙烯装置丙烯制冷压缩机系统为例，从实际开工运行后出现一段吸入罐液位持续高的问题入手，通过现场实际查找以及探讨论证后，分析得出设计与实际运行存在差异的根本原因是一段吸入罐顶的温控阀内漏。在装置运行期间采取工艺调整、新增热线等措施切实有效的解决了问题，从而保证了丙烯制冷压缩机安全平稳长周期运行。

Abstract:

This paper takes the propylene refrigeration compressor system of an ethylene plant as an example, and analyzes the problem that the liquid level in the first stage suction tank continues to be high during actual operation. After field investigation and discussion, it is concluded that the root cause of the difference between design and actual operation is the internal leakage of the temperature control valve on top of the first stage suction tank. During the operation of the ethylene plant, such measures as making process adjustment and installing a new pipeline for transporting hot propylene gas were taken to effectively solve this problem, thus ensuring the safe, stable and long-term operation of the propylene refrigeration compressor.
