A breath of fresh air

Is it possible to accomplish the regasification of LNG using no fuel, no power and no moving parts? What would be the implications of doing so? What are the benefits to the environment? Regasification of LNG is something that is rarely understood completely and seems to be shrouded in mystery in the minds of some. LNG vaporisers are quite commonplace. Following any liquid supply chain, from a 10 000 gal. ISO container to a 70 million gal. LNG carrier, will lead to a vaporiser that can take a variety of forms.

It takes energy to achieve regasification, and where that energy comes from is the key distinction between the various types of vaporisers. Energy comes in all forms, but some of the more popular sources for regasification include ambient air, seawater, cooling tower water, steam, electricity or even combustion of the natural gas itself. Significant interest has been devoted to using ambient air as an energy source due to its infinite free supply, zero environmental impact and lack of operational complexity. This article will explore some of the industry background, operational explanation and modern day examples of ambient vaporiser installations.
