About this Course

Compressors are widely used throughout the oil and gas industry, in LNG plants, natural gas pipelines, gas stations, onshore and offshore production platforms. By elevating the pressure of gas, compressors are used to liquefy and transport natural gas from one location or process to another. This was a challenge during the early years of the oil and gas industry. Conventionally,  compressors are mechanically driven by a gas turbine, however, electric driven compressors systems offer superior performance in most cases. Compressor end users face many challenges with their compression drivers. Environmental and noise concerns The Use of a gas turbine as the compressor driver brings with it environmental concerns, as a result of greenhouse gases emissions. Turbines are mostly used for power generate, by coupling it unto a Generator. The fluid can be steam or gas under high pressure. Instead of coupling the turbine unto a Generator, it can be coupledunto a compressor or pump for oil and gas production processes.

This course describes the different types of compressors and turbines found in process plants. It progresses in units from basic terminology to the principles of operation of reciprocating and centrifugal compressors and steam and gas turbines.

Course Objectives:

On completion of the course the student will be able to: 

• Explain the basic terminology used in describing compressor and turbine operations.
• Explain the functions and classifications of compressors and turbines in process plants, and identify the different types of prime movers used to power compressors.
• Identify suction scrubbers and explain how they work.
• Explain the basic principles of operation of reciprocating compressors including capacity control methods, control of suction pressure, and automatic shutdown systems.
• Explain the basic principles of operation of centrifugal compressors including capacity control 'Methods, surge control, and automatic shutdown systems.
• Explain the basic principles of operation of gas turbines, steam turbines, and turbo‑expanders.
