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.
Claims9
A liquid carbon dioxide supply device capable of supplying liquid carbon dioxide to a supercritical fluid apparatus, comprising:
- a first flow path through which a refrigerant flows;
- a pump;
- a second flow path which is provided at a position farther upstream than the pump and through which liquid carbon dioxide flows;
- a compressor that circulates the refrigerant through the first flow path such that a refrigerant cycle is repeated;
- and
- a heat exchanger that is provided at a position farther upstream than the pump, exchanges heat between the first flow path and the second flow path and cools liquid carbon dioxide flowing through the second flow path by the refrigerant flowing through the first flow path,
- wherein the pump is configured to be capable of supplying liquid carbon dioxide flowing through the second flow path to the supercritical fluid apparatus.
