Process for producing compressed natural gas from liquefied natural gas

Abstract: PURPOSE:To obtain a compressed natural gas having arbitrary pressure, economically, saving the power consumption, by compressing liquefied natural gas, pressing into a pressure vessel, and heating the gas to effect the evaporation and expansion of the gas in the pressure vessel. CONSTITUTION:A liquefied natural gas (LNG) pressurized to a definite pressure with a compression pump 4 is introduced through a heat-insulated pipe 6 into an LNG dispenser 7, and pressed into a compressed natural gas (CNG) tank 12. The LNG is heated by the ambient heat (atmospheric heat) or by a forcive heating means, and evaporated and expanded in the vessel to obtain a CNG having a desired pressure.

Gas engine and compressed gas power system

Abstract: The gas engine operable with compressed qas, such as the compressed gas from the compressor, is also fluid jacketed to be able to cool ambient temperature atmospheric fluid so that fluid yields its heat energy to the compressed gas to provide a greater power output than the potential energy in the compressed air alone.S Cooling of the compressor has the advantage of reducing the load on the prime mover and in addition to providing a useful product of heat energy. Heating the gas in the gas engine has the advantage of increasing the energy output of the gas engine in addition to producing a useful product of cool fluid. Energy from the power generation system may be usefully stored in hot water, fluid or in compressed gas and the energy of cool fluid may be used. Great efficiency is effected when used, cool, compressed gas from the gas engine can be recirculated to the intake of the compressor to reduce the energy necessary to drive the compressor in the production of compressed gas.
