Food Processing: A Cryo Central resource from the CSA

Apr 18, 2008· The major process we will study is food freezing in its many forms, using ammonia, carbon dioxide or liquid nitrogen. When discussing cryogenics and food processing, we usually take a broad definition of the term "cryogenics," extending it to include carbon dioxide, which in its various forms is a very useful food cooling substance.

LNG and natural gas processing plants | Linde Engineering

LNG is natural gas in its liquid form. In order to liquefy natural gas, it must be cooled to cryogenic temperatures of approximately -160°C. As a liquid, natural gas occupies only 1/600 of the volume of natural gas (at atmospheric pressure) in its gaseous form and therefore allows for more economic and practical storage.
