Utilization of LNG Cold is important from the view-point of saving energy since the amount of LNG used will be more increased in the future. So far only a part of the cold is used for an air separation plant and a super freezing warehouse in our country. Studies on other new applications like, for example, crushing of scrapped metals and tires at low temperature are being made by many engineers and some of them have been proved to be technically possible, though economic or other terms are not satisfactory. Therefore it is expected that utilization of LNG cold will go towards wide and large scale combination of such processes as storage, handling and distribution of foods and garbage disposition. This affords profits which are not available if those undertakings are schemed individually.
