Market Need

Nitrogen Rejection Adsorption SystemIt is well recognized that a large portion of natural gas reserves are contaminated – about 15% in the USA. With all the challenges of producing natural gas a contaminated reservoir is not a welcome result but with cost effective - and equally importantly easily operated and reliable treatment – contaminated gas can be economically brought to market. If blending is not an option, removing the nitrogen (or N2 plus CO2) with a Molecular Gate system can be an economical alternative. With two dozen systems in the market, the proven and cost effective technology is the leading option for upgrading nitrogen contaminated stream.

Processing Costs

The cost to remove nitrogen is case specific and the nitrogen removal system is only part of an overall pipeline quality gas delivery system.  Molecular Gate nitrogen systems handle flows as low as 0.5 MM SCFD at a processing cost that is typically in the range of $1.00/MCF.  To this cost is added the peripheral costs of gas production and delivery.  As flows increase the economy of scale improves the economics such that a 2-4 MM SCFD system will have a capital plus operating cost in the range of 50 cents/MCF and a larger system of 10 MM SCFD will have a processing cost in the range of 35 cents/MCF.

The Molecular Gate technology is focused on this range of flow rates with commercial systems covering this flow range.
