Twister BV and Petronas have organised a joint development programme to use Twister technology for the monetisation and processing of acid gas fields containing large amounts of CO2
Part of the programme is to develop, fabricate and test a skid mounted crystalliser vessel for qualification, aiming to confirm functionality, prove concept of melting CO2 solids and produce liquid CO2 ready for reinjection.
Similar to the proprietary Twister hydrate separator, the Crystalliser vessel aims to handle a solid phase, although it operates in a low temperature cryogenic environment.
Presently, Twister technology is qualifying for an offshore application for CO2 removal using a cryogenic setup. The alternative technology consists of a vast area of membranes that considerably increases the size and weight of the offshore structure. The main feature of the cryogenic approach is the generation of solid pure CO2.
Using an adaptation of Twister’s Hydrate Separator, the solid CO2 is melted in order to enable reinjection of CO2 into the reservoir through pumps. This adaptation of Twister’s Hydrate Separator is called the Crystalliser.
The qualification test is scheduled for Q2 2018 in Petronas’ UTP facilities in Malaysia and is a major component of the joint technology programme, which includes the development of the Twister Supersonic Separator for CO2 removal.
