How can efficiency be optimized in cases where high pressure is needed for purging, testing or other high pressure applications? First, it is important to understand the application and the factors that play into system design. Once the application is better understood then consideration needs to be made for the specific installation and location. Sometimes, the “best” method is not the most practical or cost effective. And supply of materials or availability of services can be a restraint.
One of the major justifications for liquid cylinders or cryogenic bulk tanks is the ability to get molecules to a user in a lighter and more compact package. Depending on the gas used, one liquid cylinder might be a direct replacement for a 12- or 16- pack of high pressure gas cylinders. This one 4L DOT cryogenic liquid cylinder full takes up only a 21” square footprint and weighs well under 1000lbs versus the high pressure pack with a 4x4 or so footprint weighing 3000 pounds plus. And- a 500 gallon GOrilla portable cryogenic vessel could take the place of ten high pressure packs at only 8000 pounds or so full.
An application can be a real bear when the minimum pressure is high enough to require high pressure gas cylinders or tubes and the volume of gas used is fairly high. In many cases, this can result in the need for a dozen or more high pressure 12- or 16-packs on site with a like amount committed back at the plant for exchange. This becomes an even bigger issue when the volume of oxygen, nitrogen or argon molecules needed necessitates a high pressure tube pack or trailer. If tubes are exhausted it becomes necessary to:
a) have a complete replacement pack;
b) have a spare for exchange stock or
c) have the ability to “bump” the tubes in the field.
