Since its commercialization in 2001 the Kirkpatrick Honor Award winning Molecular Gate technology has achieved rapid and growing market success with over two dozen projects underway.

The systems are noted for ease of operation, ability to produce pipeline quality sales gas regardless of the feed composition and minimal pretreatment  requirements.

The Molecular Gate technology is offered as modular plants by Guild Associates, Inc the designer and fabricator of the systems to date.

Originally developed by Engelhard Corporation, Guild is the exclusive licensee of the technology and has been involved in the technology from inception to the current state of the art.

The Molecular Gate technology is used for Nitrogen Rejection to remove N2 or mixtures of N2 and CO2 and for Carbon Dioxide Removal alone from contaminated streams.

Typical Feed sources are contaminated natural gas, landfill gas (with or without bulk CO2 pre-removal by membranes) and the gases associated with coal mining.

Smaller flows can be processed in our Spec Plants that can be purchased or rented.

Guild also offers adsorption based system for dew point control through the removal of heavy hydrocarbons and water, purification of natural Gas to meet CARB standards, TSA systems for dehydration and for a variety of gas cleanup applications such as CO2 removal from contaminated ethane.
