BW Offshore selects UOP technology to clean UK natural gas

Honeywell's UOP has been selected by BW Offshore to remove contaminants from natural gas aboard a new floating production, storage and offloading (FPSO) vessel off the coast of Scotland.

The vessel, which will be leased to Premier Oil, will include a UOP Separex membrane system to remove carbon dioxide. While the technology has been successfully used elsewhere, this will be the first FPSO in the North Sea to use a membrane-based treatment system.

UOP guard bed adsorbents will also be used to remove mercury and hydrogen sulfide.

These contaminants must be removed to meet export and end-user specifications, and to protect downstream equipment.

“UOP is continually innovating to create lightweight, compact, chemical-free equipment that is ideal for the complex offshore gas environment,” said Rebecca Liebert, senior vice president and general manager of UOP's gas processing and hydrogen business unit.

“By integrating UOP Separex membrane technology and guard bed adsorbents into a single system, we are able to create a solution that improves gas processing efficiency while reducing operating costs for FPSO operators," she added.

Scheduled for start-up in 2017, BW Offshore’s FPSO will be located approximately 125 miles east of Aberdeen, Scotland, in the Catcher oil field, in which Premier Oil has a 50% operating interest.

It will have a processing capacity of 60,000 bpd of oil and a storage capacity of 650,000 bbl.
