Abstract

Energy recovery from wastes represents an important trend to reduce the amount of an electricity energy that is produced from fossil fuels. Adsorbed methane gas (AMG) storage technology count a recent alternative and will compete with strongly the compressed methane gas technology by virtue of achievement capability for a high energy density. The innovative technology utilizes the attendant property of an activated carbon adsorbent and its general tendency for methane gas storage near the from liquid phase in a high energy density. The current study presents the method implementation for adsorbed methane gas system aiming to store gas under different adsorption pressures and temperatures with a high density as well to improve the heat exchange process for adsorption and desorption cycles. This is achieved by design and installation a heat exchanger been beside gas tank as type of thermal control systems, allowing to store a larger amount of adsorbed gas by reducing the temperature of the gas before the storage process. Performance evaluation of the developed system was based on the following indicators: storage pressure, adsorption efficiency, gas flow rate and energy production as well the energy balance (net energy output) of the gas storage system. The developed system is capable of storage 170 Volume/Volume with an adsorption efficiency of 94.40% which is equivalent to 18.89 kWh of net energy output at pressure of 3 MPa and adsorption temperature 283 °K.
