The use of industrial gases in many industries is commonplace and the demand for various types of industrial gases such as oxygen, nitrogen, hydrogen, and argon continues to rise. Some of these industrial gases are quite expensive and most are commonly delivered at pressures of 2,000–2,600 psi in steel cylinders. Unfortunately, due to the natural properties of many industrial gases and pressure limitations of the supply cylinder, users often fail to retrieve all the industrial gas that is contained within the cylinder. Often, gas cylinders are returned to the industrial gas supplier, not because they are completely empty, but because the precious gas remaining in them cannot be accessed due to low-pressure levels.
What does this mean to many users of industrial gases? Unbeknownst to them, some volume of gas remains unused and is given back to the industrial gas distributor. In other words, gas that has been bought, and paid for, is given back to the gas supplier, free of charge. The industrial gas supplier does not offer a credit or refund for the residual gas remaining in the returned cylinders. This is definitely a sweet deal for the industrial gas supplier, but a not-so-sweet deal for those purchasing the industrial gases. How expensive is this not-so-sweet deal? Depending upon the type of industrial gases used and the quantity of industrial gas purchased, it is likely this problem is costing those consuming large volumes of industrial gases thousands of dollars each year.
How does one know if they are returning gas cylinders to their supplier before they are empty? Check the pressure-gauge reading on the gas cylinders being returned or exchanged. Unless the pressure gauge is reading close to zero psi, it is very likely the cylinder contains unused gas. Checking the weight of a cylinder is another method that can be used. The weight of an empty gas cylinder is typically known or can easily be determined. If the weight of a cylinder being returned or exchanged exceeds this known weight, it very likely contains gas that remains unused.
Now that your awareness to this relatively unknown problem has been raised, the following question typically comes to mind: “What must be done to ensure that all the gas purchased will be used, and not given back to the industrial gas supplier?”.
Recognized as one of the world’s largest manufacturers of gas booster products, Haskel International is no stranger to this dilemma faced by many buyers of industrial gases. Haskel offers a full complement of gas boosters and gas booster systems designed to make full use of the industrial gases being supplied. The terms, air-driven gas booster, air-driven gas pump, pneumatic-driven gas booster, and pneumatic-driven gas pump are also used to describe gas-pressure-boosting devices. With the use of a Haskel gas booster or gas-booster system, no longer will gas cylinders be returned to the industrial gas distributor with residual gas remaining unclaimed.
How does a Haskel gas booster or gas-booster system successfully scavenge residual gas from a gas cylinder? In short, a residual quantity of gas will remain in a gas cylinder when the minimum pressure drops below the pressure required by the application to which the gas is being fed. By design, a Haskel gas booster or gas-booster system will boost the pressure of the gas remaining in the cylinder above the minimum gas pressure required by the application consuming the gas, thereby making the residual gas consumable. Gas that has been bought, and paid for, is no longer being returned to the industrial gas supplier.
Haskel gas boosters offer an added feature that is a significant benefit when the application requires the use of a potentially explosive gas, such as pure oxygen or hydrogen. Haskel gas boosters are not electrically powered and thereby eliminate the possibility of gas combustion or explosion due to an electrically related malfunction, such as sparking.
So, only one question remains. Once you optimize your use of each industrial gas cylinder, what will you do with the all the money potentially saved?
