Our innovative Bio-CNG production utilizes L-PSA technology, which is an enhancement of the existing VPSA technology. This uniquely integrated system, augmented with an energizer, reduces energy consumption while maximizing methane removal efficiency, resulting in minimal losses. The purified bio-methane can then be further compressed, making it equivalent to compressed natural gas (CNG) and suitable for use as a vehicle fuel.
Our innovative system has been operating successfully and has powered numerous small fleets with biogas sourced from landfills, wastewater treatment plant digesters, in addition to food and agricultural waste – all at a fraction of the cost of fuel!
While most Bio-CNG units come in sizes of 50, 100, and 200 standard cubic feet per minute (scfm), our systems can process biogas ranging from 20 to 2000 scfm, producing 100 to 10,000 gasoline gallon equivalents (GGE) of Bio-CNG per day. This versatile fuel can be used directly or blended with natural gas to create a hybrid vehicle fuel.
Our modular Bio-CNG systems can effortlessly expand to accommodate increased gas production. After thorough cleaning and conditioning, our Bio-CNG fuel meets stringent BIS standards and fuel specifications set by engine manufacturers, allowing it to be used without modification in the same engines as natural gas-CNG.
Our LPSA system are both economical and affordable given that their operational and maintenance costs are approximately 25% of conventional fuel or diesel costs and other comparable upgrading technologies.
