Abstract
A liquid carbon dioxide supply device is configured to supply liquid carbon dioxide to a supercritical fluid apparatus including a separation column, and includes a first flow path, a second flow path, a compressor, a heat exchanger and a pump. The compressor circulates a refrigerant through the first flow path such that a refrigerant cycle is repeated. The heat exchanger exchanges heat between the first flow path and the second flow path. The pump supplies liquid carbon dioxide flowing through the second flow path to the separation column of the supercritical fluid apparatus.
