低压瓦斯回收系统主要包括气柜系统和火炬系统两部分,气柜回收的低压瓦斯气,通过压缩机增压至0.5MPa,并入全厂的高压瓦斯管网作为燃料气使用,从而彻底解决了低压瓦斯放火炬的问题,节约了能源,杜绝了炼厂常明灯现象。低压瓦斯增压目前使用最多的是螺杆压缩机,螺杆压缩机的转子冷却多采用喷油或水方式。某厂在长期运行中,发现螺杆压缩机转子处出现大量硫磺结晶,造成螺杆堵塞,导致非计划停机。通过调查,发现结晶的主要原因是螺杆压缩机的瓦斯气分液罐内的冷却硫化柴油中含大量硫化氢,所以通过控制上游瓦斯气的硫化氢含量及增加冷却采油的置换频率,更换新鲜柴油,可以达到降低压缩机内部硫磺结晶、延长气柜寿命的目的。的翻译是:
