“…4 shows the amount of adsorbed mass in the AC bed during the charge process. The adsorbed mass for the experimental operating conditions are evaluated using the adsorption parameters for methane/Maxsorb III pair reported by Loh et al 14 . It can be seen that the AC bed attains its maximum capacity of gas adsorption within 10 minutes of the charge period when water is circulated to remove the heat of adsorption.…”

An adsorbed natural gas (ANG) storage system with internal thermal control, based on fin and tube type heat exchanger is investigated in this study. The adsorbent bed, which consists of Maxsorb III activated carbon packed in between copper fins and tubes, is demonstrated to study the storage capacity and thermal management of the ANG storage system. The cylinder is pressurized up to 35 bar and water is circulated through the tubes during charge process for quick removal of adsorption heat, thus to increase the storage capacity. Similarly, the adsorbent bed is heated up during discharge process to maximize the gas delivery. The current experimental arrangement presented shows higher storage capacity and better thermal management than the adsorbent bed without fin and tube arrangement.

The article provides an introduction to innovative method of Liquid Natural Gas (LNG) physical exergy practical utilization. The energy spent to liquefy natural gas (a thermodynamic minimum is about 0.13 kWh/l of LNG depending on pressure and chemical composition) can be partly recovered in the system making use either of the LNG low temperature (111 K) or its ability to increase the pressure in a storage vessel by heat absorption from the environment. The paper presents estimation of the LNG physical exergy and its dependence on the pressure and temperature. Then description and comparison of available natural gas storage methods (liquefaction, compression, adsorption) is given, with a special attention paid to Adsorbed Natural Gas (ANG) technology. Original data concerning adsorption isotherms of methane with activated carbon MaxsorbIII are presented. A concept of ANG storage technology coupled with the LNG regasification, is a promising technique of utilization of the LNG cold exergy. The energy efficient combination of ANG with LNG may help market progress of adsorption technology in natural gas storage and distribution. The ANG/LNG coupling is especially perspective in case of small capacity and distributed natural gas deposits exploitation.
