Petronas to test CO2 treatment technique

Offshore staff

RIJSWIJK, the Netherlands – Twister and Petronas have entered into a joint development concerning application of Twister technology for processing of acid gas fields containing large amounts of carbon dioxide (CO₂).

This will involve developing, fabricating, and testing a skid-mounted Crystallizer vessel for qualification and proving the concept of melting CO₂ solids and producing liquid CO₂ for re-injection. 

The Crystallizer vessel is similar to the Twister hydrate separator: both technologies are designed to accommodate a solid phase, although the Crystallizer vessel operates in a low temperature cryogenic environment.

Currently Twister technology is qualifying for an offshore application for CO₂ removal using a cryogenic setup.

The main feature of the cryogenic approach, the company says, is the generation of solid pure CO₂ (dry ice). Through an adaptation of the hydrate separator (the Crystallizer), the solid CO₂ is melted to allow reinjection of CO₂into the reservoir through pumps.

A skid fabricated in the Netherlands containing Crystallizer and test control equipment is on its way to Malaysia to undergo qualification tests.

The qualification test is scheduled for 2Q at Petronas’ UTP facilities in Malaysia.
