It is generally accepted that a minimum economic level for LNG import/export project is in the neighbourhood of one million tons per annum.
Since a first small scale LNG plant was developed in the U.S.A., about sixty of such plants have been built in the world. These small plants are all for peak shaving purposes and not for base load plants.
Drastic changes of the energy situation in the past few years have so far influenced the basis of evaluating the value of energy from political and economical stand points.
Further careful study of a total system involving liquefaction, storage and transportation will bring about a possibility that the erection of a small base load plant, not regarded as economical prior to the advent of the energy crisis, will become economical and viable.
The application of a mobile plant will become further advantageous in solving construction problems arising from unknown local conditions, and its mobility will be useful for the utilization of small gas sources which are rather short-lived.
The utilization of a mobile plant for a small scale LNG project will not only contribute greatly to a producing country but also meet the ever-increasing need of a clean pollution-free energy in a consuming country.
