After a hot summer, the supply of liquid carbon dioxide and dry ice still remains limited. In addition to regular autumn maintenance turnarounds in succession at the side of supply sources, there was trouble at the West Japan sources this year which lead to no sufficient crude gas being supplied.

Shortages of liquid carbon dioxide and dry ice are often common during the summer months, however this year similar shortage trends continued into the autumnal season.

The shortage has been caused by the lowered supply rate of crude gas due to the output adjustments and plant troubles.

Shortages coincide with the regular maintenance turnarounds at the supply source side of oil refineries or ammonia plants, where there is an inevitable decrease in the number of outlets to discharge crude gas in comparison with the summer season.

Usually the autumn demand is stable due to the cooler climate, but the issue of a tight supply is too serious to keep up with the decreased demand.

Prior to summer, no adequate stock of liquid was secured, and supply sources of crude gas entered their turn-around period after overcoming the peak summer season, this resulted in the tight supply in autumn.

In terms of imported dry ice from Korea, no adequate procurement was possible. In Korea the demand of cooling transportation by dry ice is also high, the country pointed out that the allocation of supply of crude gas has decreased due to the rising needs of carbon dioxide for chemical materials.

There are many issues disturbing a stable supply for COand dry ice suppliers, the issues have been weighing on the profitability for the suppliers.
