干式气柜密封油的应用与发展

Application and Development of Sealing Oils for Dry Gas Holder

气柜主要用于煤气等可燃气体的收集、储存与配送,干式气柜是用润滑油为密封介质,因其容量大已成为气柜发展的主流。作为密封介质的干式气柜密封油以精制矿物油为基础油,加入抗氧、防锈、降凝等添加剂调制而成,其特点是使用周期长,具有优异的防腐性及油水分离性,有不同的系列产品可以应对储存气体及环境温度的影响。在使用过程中要密切监控质量变化,通过定期补加添加剂或换油等措施来维持油品性能稳定。为充分利用一切可燃气体,普及民用燃气,会更多地用到干式气柜并促使密封油发展。润滑油生产企业应重视这一发展,不断提高产品性能,提供优质服务来满足用户需求。

The gas holder,which employs lubricating oil as sealing medium,is used to collect,store and distribute combustible gases,such as coal gas and refinery gas.It has become the development mainstream because of the high capacity.Dry gas holder sealing oils are prepared by using refined mineral oil as base oil and adding some additives like anti-oxidant,anti-rust agent,pour point additive etc.The oils have characteristics of longer service life,excellent corrosion protection and oil-water separation.Different product lines can adapt to different gases and environmental temperature.The oils＇ quality changes should be monitored closely in the process of use.Some measures,such as replenishing additives or oils change,can be taken to keep oils performance stable.To take full advantage of all combustible gases and popularize civil gas,the dry gas holder will be more used to promote the development of the sealing oils.Lubricating oil producers should pay attention to this development,and constantly improve the product performance,provide high quality services to meet the needs of users.
