A METHOD AND APPARATUS FOR THE DELIVERY OF COMPRESSED GAS IN THE FIELD

摘要

The invention is a method and apparatus for delivering large volumes of nitrogen gas, air, or other gas at high pressures from banks of high pressure cylinders and releasing that gas at the rate required by the operation. Not only can higher flow rates be achieved, but the absence of motors or engines can be an advantage in hazardous areas and can increase the reliability of the delivery of the gas. In addition, as compared to using liquid nitrogen, which typically must be delivered from a remote air separation plant, these banks of cylinders can then be recharged with gas by portable compressors or nitrogen generators.
