裂解气压缩机透平在线清洗技术应用

Application of Online Cleaning Technology for Cracking Gas Compressor Turbine

中国石油辽阳石化分公司裂解装置裂解气压缩机在运行过程中,由于水质原因造成透平结垢,转数提不起来,蒸汽耗量增加,高压蒸汽不够用,机组能力下降,,达不到要求的生产负荷。工艺和设备人员分析、判断,确认蒸汽透平结垢,能力下降。经过文中主要阐述利用饱和湿蒸汽对机组透平在线清洗的技术应用,包括清洗前后效果对比。确保机组稳定运行。

During the operation of the cracking gas compressor in the cracking unit of PetroChina Liaoyang Petrochemical Company,due to water quality,the turbine was scaling,the number of revolutions could not be raised,the steam consumption increased,the high-pressure steam was insufficient,the unit capacity decreased,and the required production load could not be reached.The process and equipment personnel analyzed and judged and confirmed that the steam turbine was scaling and the capacity decreased.This paper mainly describes the application of saturated wet steam to on-line turbine cleaning,including the effect comparison before and after cleaning,so as to ensure the stable operation of the unit.
