HNNG Development's strategy is to exploit commercially proven, proprietary technology for removal of nitrogen from natural gas – bringing to market energy resources that could not otherwise be produced. Throughout the world, there are more than one thousand conventional natural gas fields that are considered sub-quality because the natural gas contains more than 4 mol% nitrogen. According to the Gas Technology Institute, approximately 16% (over 24 TCF) of United States proven domestic natural gas reserves falls within this category. More

HNNG’s nitrogen rejection technology is generally referred to as the AET Process. This process, developed and patented by Advanced Extraction Technologies, Inc. (AET) of Houston, Texas, is a physical absorption, solvent-based alternative for rejection of nitrogen from natural gas. More
