摘要/Abstract

摘要： 某高含硫气田共有4套天然气净化处理联合装置，每套装置配备2台克劳斯风机，其中1台由蒸汽透平驱动。汽驱克劳斯风机是硫磺回收单元的关键节能环保设备，其蒸汽透平在启机、运行过程中多次出现因振动过大触发高高联锁导致跳车的现象。蒸汽透平维修时间长且维修难度大，其异常跳车会严重影响装置的正常生产和设备的正常使用、维护。文章通过对蒸汽透平启机过程振动跳车数据、现场管道走向、现场机械运行情况进行分析研究，确认导致其跳车的主要原因为蒸汽透平出入口蒸汽管道存在偏差。针对导致跳车的原因，从增设蒸汽出口管道阀门、变更蒸汽透平出入口管道、增加管道倒链、增加管道弯头支撑、优化管道支架型式5个方面进行改造，有效解决了机组因振动跳车的问题，保障了联合装置的平稳运行。

Abstract: A high-sulfur gas field is equipped with four natural gas purification processing units, each unit having two Claus blowers with one of them driven by steam turbine. The steam turbine-driven Claus blower serves as a critical energy-saving and environmentally friendly device within the sulfur recovery unit. However, its steam turbine has repeatedly experienced trips during startup and operation due to excessive vibration triggering the high-high interlock. Steam turbine maintenance is both time-consuming and complex, and these unexpected trips severely disrupt the normal production of the unit, as well as the regular use and maintenance of the equipment. This paper analyzed vibration trip data during steam turbine startup, along with on-site pipeline routing and mechanical operation conditions. The analysis confirmed that the primary cause of the trips was misalignment in the steam inlet and outlet pipelines of the steam turbine. To address the root cause of the turbine trips, improvements were implemented focusing on five key aspects: installing additional valves to the steam outlet pipeline, retrofitting steam turbine inlet and outlet pipelines, adding pipeline chain block, reinforcing pipe elbow supports and optimizing the types of pipeline supports. These modifications have effectively resolved the issue of unit trips caused by vibration, thereby ensuring the stable operation of the natural gas purification processing units.
