Integrated process solutions provider ProSep will supply one unit of ProDry natural gas dehydrator to Statoil ASA (NYSE: STO) for the North Sea Troll B ZMP project, according to a Feb. 14 press release.

Statoil will receive the ProDry unit through ProSep’s scope of supply, which was awarded through Aker Solutions. ProSep’s scope of supply began in January and will last about five months, the press release said.

When ProDry technology dehydrates natural gas, standard countercurrent towers are replaced, eliminating large vessels and internals, Greg Hallahan, ProSep’s director of product development, said.

On the Troll B Platform, ProDry will use ProSep’s Eclipse mixer for triethylene glycol (TEG) injection, and Statoil will replace a standard countercurrent TEG tower with an inline co-current mixer and separator/knockout drum. The required TEG flow compared to a conventional tower will be reduced, allowing the project to utilize spare capacity in the existing TEG regeneration packages, the press release said.

Jacek Kacperski, ProSep sales manager for Europe, said this will be the first time the Eclipse mixer was installed for gas dehydration with TEG or MEG, the ProDry application, although it has been used for hydrogen sulfide scavenging on the Norwegian Continental Shelf. Kacperski said this project concludes one year’s R&D and business development effort to reach commercialization.
