Since the 1600s, chemists have known that temperature can determine whether a substance exists as a gas, liquid, or solid. Johannes van Helmont, who coined the term gas to describe carbon dioxide, used a different term, vapors, to describe substances...

Liquefaction of gases includes a number of processes used to convert a gas into a liquid state. The processes are used for scientific, industrial and commercial purposes. Many gases can be put into a liquid state at normal atmospheric pressure by simple...

PROJECT OVERVIEW: A Brazilian joint venture that teams-up WHITE MARTINS GASES INDUSTRIAS LTDA , a subsidiary of US-based PRAXAIR INC., and PETROLEO BRASILEIRO S.A. (PETROBRAS) is currently gearing-up to build a new gas liquefaction plant in Brazil. The new facility, to be...

Axens (Paris, France; www. axens.net) is set to commercialize a dual-stage liquefaction process dubbed Liquefin (Figure 1) that will produce about 15% more liquefied natural gas (LNG) than competing technologies using the same gas turbines and power input. "The increased capacity for gas turbines...
