Storage and delivery systems for gases held in liquid medium

A low pressure storage and delivery system for gases which comprises:

• a container having an interior portion containing a reactive Lewis basic or Lewis acidic reactive liquid medium that is reversibly reacted with a gas having opposing Lewis acidity or basicity;
• a valve system having an inlet port for the introduction of gas and reactive liquid medium to the vessel and an outlet port for delivery of gas;
• a system for inputting energy into the reactive liquid medium comprised of a sparger tube and,
• a gas/liquid separator which is pervious to gas and impervious to entrained liquid droplets as gas is delivered from the container.

A process for the delivery of product gas from a storage and delivery system which comprises:

• charging a Lewis basic or Lewis acidic reactive liquid medium to a container having an interior portion;
• charging the container with a source gas containing a Lewis basic or Lewis acidic reactive gas having opposing Lewis acidity or basicity that reversibly reacts with said reactive liquid medium having Lewis acidity or basicity;
• collecting the excess unreacted source gas in a headspace in said container;
• venting said excess source gas from the head space in said container to remove impurities that have concentrated in the headspace;
• and then,
• delivering a product gas.

A process for the delivery of product gas from a storage and delivery system which comprises:

• charging a Lewis basic or Lewis acidic reactive liquid medium to a container having an interior portion;
• purifying a source gas containing a Lewis basic or Lewis acidic reactive gas having opposing Lewis acidity or basicity that reversibly reacts with said reactive liquid medium having Lewis acidity or basicity to remove impurities present in the source gas;
• introducing the purified source gas into a container;
• and
• delivering a product gas.
