Course Description

Gas compressors are used in power and gas fields in many applications such as gas boosting, gas lift, gas re-injection and vapor recovery systems. Gas compression projects often encompass many engineering disciplines and different technologies. This course presents an overview of gas compression technologies. It provides participants with an underpinning knowledge of gas compression using a variety of rich multimedia techniques. It examines the different types of gas compressors in use, gas compression systems, and the use of reciprocating and centrifugal compressors.
 

Course Goal

To enhance the participants’ knowledge, skills and abilities necessary to understand different types of gas compressors in use, gas compression systems, and the use of reciprocating and centrifugal compressors.
