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.
