Recent Technologies For The Reliability And Performance Of Mechanical-Drive Steam Turbines In Ethylene Plants.
MetadataShow full item record
Recently, large capacity ethylene plants have been constructed in the world and the trend for the capacity of these plants is increasing. At present it reaches up to about one million tons per year and more. Accordingly, the mechanical drive steam turbines in the ethylene plants become larger and their shaft end power increases. Also the requirement for long-term continuous operation and high performance of these turbines becomes more important year by year in order to save operation and maintenance costs. This paper focuses on mechanical drive steam turbines in ethylene plants and introduces the recent technologies for reliability and performance improvement. Some of these technologies have already been successfully applied to actual steam turbines.
