Course Description

Cryogenic   turbo-expanders   are   used   in   many   applications, including ethylene plants, refineries, gas processing plants, and air separation facilities. They frequently produce the coldest level of refrigeration available in the plant, and often operate with turbine outlet conditions where large quantities of liquid are condensed during the expansion process.

Turboexpanders  have  come  a  long  way  in  the  last  20  years. Their  high  efficiency  and  reliability  have  led  to  widespread  use around the world. The use of magnetic bearings in many critical turboexpander applications such as ethylene  plants  has  become common, and in the natural gas processing market, they are making inroads  as  well.

This course explains how turbo expander design features and how it works and the critical conditions in expander operations and troubleshooting. The course then discusses hydrate formation in turbo expanders and the operation of a turbo expander, including bearings and seals, lube oil system and the seal gas system.

API  617  (2002)  now  addresses  cryogenic  turboexpanders  in Chapter 4 of the Seventh Edition. Annex 4F of the same document provides guidelines for purchasing equipment using magnetic bearings, and this section is particularly applicable to turboexpanders.
