Many of the most sophisticated applications in the field of cryogenics have been developed at the US National Aeronautics and Space Administration (NASA).
This month, gasworld takes a look at the many ways cryogens are used in manufacturing and processing. Here we examine shrink fitting, a unique way of applying very cold temperatures to manipulate metal.
There is really no such thing as a perfect vacuum – just varying degrees of very low pressure. Even in deep interstellar space, the closest there is to a perfect vacuum, there are still a...
By far, the cryogenic freezing of food products is the hallmark of low temperature applications for the commodity that is carbon dioxide (CO2).
There is a clear growth in the number of hydrogen fuel cell vehicles on roads across Europe. Hydrogen refuelling stations are now available in several countries mapping the first hydrogen for transport network.
We live in an increasingly self-conscious world, driven by both a desire and a requirement to achieve greater sustainability. Very real evidence demonstrates the damaging footprint we are leaving on our environment. As a result, the...
Like vehicle emissions, one of the most commonly acknowledged or understood areas of environmental concern surrounds fluorinated greenhouse gases (F-gases). It’s become something of a buzz term in the wider specialty gases and chemicals business...
Bob Brown, the Australian politician once said, “The future will either be green or not at all.” As we seek to maintain our industrialised way of life in a sustainable way, employing clean technologies and...
Optimisation should be incorporated into every company’s business strategy. You should demand and accept nothing less than the best outcome for every action and activity you engage in – and cylinder filling is no exception.
Maintaining calibration test gas stability and purity in portable aluminium cylinders has long been a challenge, and the difficulty has escalated in recent years due not only to increasingly stringent regulatory requirements around the world,...
