Coal Bed Methane Gas Recovery

This application is found in coalmines where two forms of gas may be produced. One gas is from microorganisms feeding off the coal, and the other gas is from gas deposits in the mines. By drilling into the coalmines, and locating sufficient gas deposits, the gas can be recovered through vacuum, depending on suction and discharge pressures at the well head. The gas, once recovered by the low-pressure vacuum, is then compressed by high-pressure compressors to a pipeline for processing or used for cogeneration, etc. Normally the methane gas recovered is very clean but significant quantities of liquids may be entrained in the gas. This gas is recovered for a number of uses, including cogeneration and gas plant processing for redistribution of sale.

Vectra GL/XL Vacuum Pumps

The Vectra GL model, available from 120 to 830 CFM (200 to 1,500 m³/hr), is ideal for general industrial applications. It comes standard with internal mechanical seals and many Nash patented innovations including gas scavenging.

The Vectra XL model was designed to meet the stringent requirements of many CPI applications. Whether operating as a vacuum pump or compressor, it features a 30 PSI (2 bar) differential capability. It is available in ductile iron or 316L stainless steel with a variety of shaft sealing options. Sizes range from 120 to 3,000 CFM (200 to 5,000 m³/hr).
