Oil refineries and ammonia production plants are the sources of liquid carbon dioxide and dry ice in Japan. However, many of these facilities are withdrawing from business or curtailing operations.

There is, therefore, concern about a decrease in the ability of these sources to supply the gas. In November it was announced that there would be a cutback in the crude source at plants in Hokkaido and Niigata. There is a tendency for the supply of crude gas to drop as existing sources as well, so that all suppliers have been busy coping with the situation. It used to be a trend that supply of liquid carbon dioxide and dry ice really becomes tight in the summer, but this year it seems that this tightness has not dissipated even after the autumn comes.

Ammonia synthesis and oil refining are major sources of carbon dioxide and dry ice production. Curtailment of production and withdrawal from the business are following along one after the other due to the slump in domestic demand and increased international competition.

Investment in the development of new sources and plants have been made to cope with the disappearance of those sources in the liquid carbon dioxide and cry ice industries. Air Water Tansan is now under construction and should be completed early this year with an annual capacity of 90,000 tpd of liquid carbon dioxide and dry ice, using source gas from the Seibu Oil plant in Ube.
