Adsorbed natural gas storage facility based on activated carbon of wood waste origin

Adsorbed natural gas (ANG) storage is a promising solution to the problem of uneven supply and consumption of natural gas. ANG storages are relatively simple, safe and do not require complex infrastructure. The paper investigates the properties of activated carbon of wood origin synthesized by the method of chemical activation, as well as the theoretical capacity and thermodynamic properties of ANG storage facilities equipped with this adsorbent. An original graphical method for calculating the parameters and processes of ANG storage facilities is presented using the example of synthesized active carbon. Various types of ANG storage charging are considered: adiabatic processes of charging with compressed and liquefied gas, isothermal and pseudo-isothermal processes. So adiabatic charging with liquefied gas allows reaching a storage capacity of 150 m(3)/m(3) at a pressure of 3.5 MPa. A number of recommendations were made regarding the choice of the charging type from the standpoint of the ANG storage facility design.
