Gas Compression and Dehydration System

Dehydration is an important process in offshore gas processing.  The gas is dehydrated offshore to avoid the dangers associated with pipeline transport and processing of wet gas.

This course will cover the basics of gas compression and dehydration.  The characteristics and operation of various types of compressors will also be covered.

As the course progresses, discussions will focus more on the process of dehydration.  Topics covered during the discussion will include the impacts of pressure and temperature on the process, as well as safety and ESD considerations.

Day 1

Compression and Need for Dehydration

  • Overview
  • Gas hydrates
  • Documentation
  • Types of compressors

On day one, participants will gain an overall appreciation of the need for dehydration, gas compression, and the various types of gas compressors used on the oil and gas industry. They will also learn about the importance of drawings and documentation.

Day 2


  • Overview
  • Types of dehydration
  • Flow diagram
  • Operation
  • Safety and ESD considerations

Day two will focus on the types of dehydration processes available and how to use a flow diagram to better understand how the process operates. Discussions will also cover how pressure and temperature influence the dehydration process.  Safety and ESD considerations will also be covered.
