Description
図1を参照すると、本発明による装置1が示されている。標準的な300psig大容量タンク(図1には示されていない)からなどの液体二酸化炭素の供給流は、ライン10を介して装置1に入る。ライン10は、精製及び貯蔵容器12の底部に、ポート14にて接続されている。精製及び貯蔵容器12は、好ましくは一体型チャンバ、すなわち精製容器12の一体型構成要素である環状収集チャンバ32により囲まれている蒸留塔アセンブリ13を具備する。ライン10は、大容量二酸化炭素供給機から精製及び貯蔵容器12の蒸留塔アセンブリ13に、精製容器内の液体レベルに応じて、精製容器へ液体供給流を供給し及び精製容器から液体を戻すことができるように、二酸化炭素の流を顕著な制限なく戻したり進めたりするように特別に設計されている。本発明によれば、レベル制御システムが物質の流入に応答する適切な時間を確実に有するように、液体二酸化炭素のシステム1への流の速度をゆっくりにすることが望ましいかもしれない。純粋な二酸化炭素流システムの少なくともある程度の確認がシステム運転中に数回行われるであろうから、二酸化炭素の大容量源とシステム1との間の流の制御がさらに正確になる。運転中、二酸化炭素は、精製及び貯蔵容器12の底部に入って、蒸留塔アセンブリ13に入り、少なくとも沸騰型熱交換機16を実質的に浸水させるレベル15まで、蒸留塔アセンブリ13を充填し始める。
