High flow filter extends maintenance cycles and reduces costly shutdown

Compressed hydrocarbon (HC) gas is commonly used on offshore oilrigs to control instruments when compressed air is not available. Moisture, particulates or oil in the gas can damage downstream equipment and cause malfunctions that make it difficult to control the process efficiently. The Malaysian oil and gas company Petronas wanted a way to be sure the compressed gas on unmanned satellite platforms was cleaned and conditioned for safe use with the valves that control pumping operations. They needed a filtration system that was long lasting, durable and effective.

Norgren engineers in Malaysia started with an existing stainless steel filter, proven to withstand the corrosive salt-spray environment. A global engineering team then applied Norgren’s deep expertise in filtration to adapt a coalescing element used in other industries to the unique requirements of this offshore application.

Norgren developed a unique convoluted filter element that allows high flow with minimal pressure drop. The new element developed, called the F22H, also withstands aggressive sour HC gas. A three-stage system of two general-purpose filters and the F22H gives Petronas clean, dry gas on satellite platforms.
