New filter from Celeros Flow Technology

By Keefe Borden01 September 2021

Celeros Flow Technology recently released the Dollinger GP-198 coalescing filter, which is designed to efficiently remove oil, water mist, hydrocarbon condensates and other liquids and solid particles from natural gas streams. The company said the coalescing filter can remove up to 99.97% of 0.3 micron aerosols when used within its rated design conditions.

The Dollinger GP-198 coalescing filters can be used on main process gas and in between compressor stages. For remote compressor stations, the filters can be used on natural gas feed to gas turbines powering gas compressors and site generators. The Dollinger GP-198 is also suited for use as a pre-filter or separator or as part of a gas dehydration system, the company said.

The Dollinger GP-198 coalescing filter incorporates a unique, highly efficient filter element, Celeros said. The standard coalescing element consists of multiple layers of borosilicate glass media and a solids pre-filtering layer, supported by screens both upstream and down. The pleated design provides a much larger surface area than conventional coalescing elements, which results in low pressure drop, high efficiency, and extended service life.

The GP-198 coalescing filter can be specified with housings in a wide range of materials including, carbon steel, stainless steel & a variety of special alloys. Special service requirements for low temperature applications, sour & SSC conditions and ammonia applications can also be accommodated, Celeros said.

Housings are designed for top service installation with a pre-filtering sump area and multi-cartridge tubesheet mounted arrangements allowing for ease of access and maintenance, the company said. The filter housings are constructed in accordance with a wide range of international pressure vessel design codes including, but not limited to, ASME VIII Division I & IIPD5500, 2014/68/EU (PED), AS1210, SELO, GB-150-, AD2000, and GOST-R).
