Dew Pointing

Advanced gas processing with proven supersonic separation equipment

The new standard for combined water and hydrocarbon removal from natural gas is now available as a ready to install system through an alliance between American Oil & Gas and Twister. The supersonic separator technology, introduced and patented by Twister B.V., is a robust solution for commercial gas processing applications. The equipment has been proven viable for onshore and offshore application by major oil and gas producers worldwide. Together, AOG and Twister are able to offer extensive experience in gas separation fundamentals, specialty equipment design and manufacturing, as well as valuable experience in integrating gas purification solutions to best address the unique needs of your application and business.

Trouble Free Dew-pointing of Natural Gas Streams

The Twister technology uses pressure drop to cool a stream to a condition where water and heavier hydrocarbons condense and are easily separated. The supersonic gas flow design results in a more efficient separation and higher liquids recovery for the same pressure drop compared to conventional Joule-Thompson gas cooling systems.

Additionally, the efficient separation offered by the equipment eliminates the need for chemical injection to prevent hydrate formation, a limitation of conventional gas dewpointing technology. There are no moving parts and reliability is extremely high. The compact design and modular approach provides efficient use of space in offshore applications or expansions in existing facilities.

The technology is economically attractive due to ability to achieve higher liquids recovery and reduce operating costs relative to other dew-pointing systems.

Twister Supersonic gas separation is especially beneficial in the following applications:

  • Dew-pointing where additional liquids recovery is valued
  • Dehydration of sour gas streams
  • Offshore applications, especially FPSO and FLNG
  • Under Ground Gas Storage (UGS) where chemical free and fast response solutions are needed
  • Remote locations where chemical handling, operating personnel, and maintenance are to be minimized.
