摘要/Abstract

摘要：

某石化公司220 kt/a乙烯装置丙烯制冷压缩机透平存在高压侧泄漏蒸汽直排大气的隐患。为减少泄漏蒸汽直排大气，并将透平真空度控制在设计指标内，通过增加泄漏蒸汽冷凝器的措施，实现了丙烯制冷压缩机透平无泄漏，且保障乙烯装置长满优运行。

Abstract:

In the 220 kt/a ethylene plant of a petrochemical company, there was a hidden danger of steam leakage from the high-pressure side of propylene refrigeration compressor turbine directly discharged into the atmosphere. In order to minimize the direct discharge of steam leakage into the atmosphere and control the vacuum degree of the turbine within design specifications, a leakage steam condenser was added. Zero leakage in the propylene refrigeration compressor turbine was achieved, and a safe, stable, long-term, full-load and optimum operation of the ethylene plant was ensured.

Key words: propylene refrigeration compressor turbine, leakage steam condenser, vacuum degree
