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.
