Adsorbed Natural Gas Products Receives Patent for NGV Innovation
Adsorbed Natural Gas Products (ANGP) announced it has received from the US Patent and Trademark Office a Notice of Allowance for its Sorbent Based Low Pressure Gaseous Delivery System, which ANGP refers to as its Fuel Extraction Pressurization System (FEPS). The formal issuance of the patent is expected over the next 8 to 12 weeks.
The patent covers the embodiment of the ANGP FEPS in an isolation circuit designed to operate only when the gaseous storage tank on a vehicle drops below a specified pressure. This embodiment allows for increased energy efficiency of the ANGP adsorbed natural gas (ANG) based storage system in conjunction with the vehicle’s fuel injection and electrical systems.
ANGP’s isolation circuit triggered FEPS is best suited for high horse power applications requiring energy density flow at pressures in excess of 100 psi. ANGP’s low pressure storage systems designed for light duty vehicles no longer require the use of the FEPS due to the high release rate of natural gas from the ANGP system technology.
