Utilization of LNG Cold for Air Separation Plant

Abstract

In Japan, the inport of LNG has been started in 1969, and immediately it will be enlarge as the new energy source. The problem of utilizing the cold from LNG vaporization has been examined, then it has been found out that the utilization cold for air separation plant is one of the most efficient process. This paper describes the fundametal problem of the air separation plant which utilizes the cold of LNG, and economics of the process.
