The HAGUE, 18 September 2006 – Twister BV today announced the award of a major contract in Nigeria for gas processing at Shell Petroleum Development Company’s (SPDC) onshore Okoloma Gas Plant using chemical free, Twister Supersonic gas conditioning.
The Twister gas processing module will be used for dewpointing 120 MMscfd of gas which will be supplied as fuel gas to the SPDC owned and operated 970 MW Afam V1 Power Plant. The Twister module will incorporate six (6) Twister Supersonic Separator tubes together with a chemical-free Twister Hydrate Separator. The Twister tube design can achieve a water dewpoint reduction at a lower pressure drop whilst maintaining the benefits of chemical free operation without moving parts.
Twister technology was selected for the Okoloma Gas Plant due to its ability to achieve water and hydrocarbon dewpoint specification without the need for a glycol plant whilst also avoiding the need for a heat exchanger for inlet cooling.
The Twister design benefited from extensive Twister testing and operating experience at five onshore gas plants in the Netherlands, Nigeria and Norway, as well as over 2 years of successful full scale commercial operation on the Petronas/SSB B11 facility offshore East Malaysia.
Twister technology treats produced gas at supersonic velocities, extracting water and hydrocarbon liquids. Compared to conventional technologies, the Twister process requires no chemicals and hence reduces exposure to hazardous gas. It has no moving parts, permits near instant start up and allows considerable cost reduction, particularly for offshore installations.
The Netherlands-based Twister BV company was launched by Shell Technology Ventures in April 2000, and holds significant experience in natural gas processing technology development, plant delivery and operational support.
