Liquefied gases are considered volatile since they are sensitive to temperature and pressure changes. Most are thinner than water so pumping them can be challenging. Any increases in ambient temperature or pressure losses in the piping system can cause a liquefied gas to change from a liquid to a vapor. In contrast, any decreases in the ambient temperature or increases in pressure will result in a change to a liquid form. While vapor is mandatory for a compressor application, it is important ...
