Abstract

​Natural gas, from the environmental point of view, is the cleanest fuel after hydrogen. Widespread use of gaseous fuel is restricted by its storage problems in containers under high pressure (20-25 MPa) or liquefied gas at low temperatures (-163 °C). One of the most promising solutions to such problems (high pressure and low temperature) is to develop a vessel based on adsorption technology, designed for efficient storage of natural gas at relatively low pressures (3-3.5 MPa). Adsorbed natural gas (ANG) storage system provides reduction in compressor cost, tank manufacture cost and gas refueling cost (energy consumption of ANG is lower than that of compressed (CNG) and liquefied natural gas (LNG) storage systems) and improves environmental safety by transferring vehicles from gasoline to natural gas. This paper presents simulation results of charging of ANG vessel under the dynamic conditions where the heat effect is controlled by the fin and tube type heat exchanger.
