Choosing and Maintaining Lubricants

Wednesday, December 2, 2020 @ 3:00pm Eastern / 12:00pm Pacific

Presentation Synopsis

Varnish has been a problem plaguing the power generation industry for decades. With new technologies, base stocks, and testing methods out on the market how do you determine the best method for your unique system? And how do you maintain it to make sure it is reliable long term?

Using case studies and lab results, this presentation will go through the composition of varnish, its implications, and various ways to mitigate varnish. But, mitigating varnish is not a one size fits all. Many times, equipment owners need to come up with a solution where an outage or high budget is not an option. This session will cover the use of various options including filtration units, cleaning/high velocity flushing, and the top-tier chemical treatments available. With the use of actual customers results, the difference between these methods and the short/long term solutions they provide will be discussed.

This session will also discuss replacement fluids. Petroleum based turbine oils have evolved using better base oils from Group I to Group II and now Group III. Advances in lubrication have also taken place with polyalkylene glycols (PAGs) and gas-to-liquid (GTL) base stocks. The chemical makeup, solvency, and benefits of these different base stocks will be compared.
