Adsorptive Storage of Mechanical Energy (Work) for Transportation Applications
AIChE Annual Meeting, Conference Proceedings
Hydraulic accumulators are commonly used in industry to store mechanical energy to prevent intermittent operation of hydraulic pump; a gas contained in a vessel is compressed to very high pressures (200-300 bar) when there is no demand for power as the pump is "idling." Inclusion of a solid adsorbent in a hydraulic accumulator operating at such high pressures may first seem counter intuitive based on adsorptive gas storage studies mostly operating close to isothermal conditions. In contrast hydraulic accumulators, particularly for transportation applications, operate under adiabatic conditions making it possible to exploit adsorption phenomena in a different mode. The application and experimental data for several solid-gas pairs under realistic conditions up to 330 bar pressure is presented. This is an abstract of a paper presented at the 2006 AIChE National Meeting (San Francisco, CA 11/12-17/2006).
