Our technical input to Society of Petroleum Engineers, Applied Technology Workshop "Production Management Best Practices for CBM Fields", held at Surfers Paradise, Queensland, 30 March - 2 April 2009:- Poster. "Selection of Field Booster Compressors for CSG Gathering Systems" Presentation. "Coal Seam Gas Wellhead Facilities. Some observations & ideas from Australian practice" News from valued clients. . .
Some references we found useful during a recent study to address means of protecting compressors from ingress of particulate matter in the coal seam gas:- This paper, through promoting a proprietary technology, is one of the best references for a chemical engineer who wishes to obtain a deeper understanding of how high- performance liquid/gas coalescing filters work. It is especially useful to assist evaluating bids from competing vendors, because it provides an understanding of technical criteria such as internal annular and media velocities. These criteria can be compared for competing proposals, to help evaluate performance at design conditions. Coalescing filters are being increasingly used in the coal seam gas industry, to help minimize compressor operating and maintenance costs (inlet gas treating) and to remove lube oil aerosol from outlet gas. This is a good summary of options for removing fine solid particulates from a gas stream. Wet dedusting uses water to wash the gas with various liquid/gas mixing mechanisms. The competing technology is advanced filter medium that can remove solids down to 0.3 micron. But where gas flows are high, pressure very low, and low pressure drop is required, the wet dedusting option is worth considering.
