HNNG Development, LLC, a provider of nitrogen removal technology for the natural gas industry, has announced the startup of the company’s first Nitrogen Rejection Unit (NRU), a proven technology for the removal of nitrogen from natural gas.


The installation and start-up of the unit for Agape Energy Alliance LLC, in Garfield County, Oklahoma is the first application to go live since the company began commercializing its solvent-based physical absorption technology in November 2005. Under the terms of the agreement, having completed the installation and start up of the project, HNNG will lease the nitrogen removal unit to Agape.


HNNG’s Nitrogen Rejection Units utilize the AET process, licensed to HNNG by Advanced Extraction Technologies, Inc., to unlock the economic potential of high nitrogen natural gas reserves that otherwise could not be brought to market due to associated compliance and quality issues. The unit installed for Agape is designed to treat natural gas with a nitrogen content of up to 50% and is capable of processing up to 1 million cf/d of natural gas, bringing it comfortably within the project’s pipeline quality specifications.
