Shell in biological desulfurization venture

By OGJ editors
HOUSTON, July 1 -- Royal Dutch Shell PLC has agreed to form a 50-50 joint venture with Paques Holding BV, a Dutch water and air purification firm, to market biological desulfurization technology for use in oil and gas operations.

The venture, Paquell BV, is adapting proprietary technology Paques has used since the early 1990s in the water business for atmospheric biogas desulfurization.

The companies said the technology, which uses natural bacteria, can remove hydrogen sulfide from produced gas and refinery gases.
