ABSTRACT:
Gas to be stored flows along a gas feed line and into a cylinder containing a solvent for the gas. During its passage along the gas feed line, the gas flows through a dosing device which, on the one hand, permits a substantially adiabatic expansion and concomitant cooling of the gas to occur and, on the other hand, automatically regulates the flow rate of the gas in dependence upon the pressure difference across the dosing device. The pressure upstream of the dosing device is maintained constant regardless of the pressure downstream thereof, which latter pressure is variable due to the fact that dissolution of the gas generates heat and an accompanying increase in the pressure inside the cylinder. The constant pressure upstream of the dosing device is slightly higher than the final pressure inside the cylinder when the latter has been filled. When the flow rate of gas into the cylinder is rapid so that large quantities of heat are generated, the pressure inside the cylinder rises so that the pressure differential across the dosing device decreases and the flow rate of the gas into the cylinder decreases. Conversely, when the flow rate of the gas into the cylinder is lowered, the heat generated by the dissolution can dissipate, the pressure inside the cylinder can decrease and the flow rate of the gas into the cylinder can increase. In this manner, the flow rate of the gas into the cylinder can always be adjusted to the absorption capacity of the solvent which decreases with increasing temperature and vice versa. Moreover, when the capacity of the cylinder is reached, the pressure inside it reaches its upper limit and the flow of gas into the cylinder automatically terminates thereby providing a high degree of safety.
