To restrain dry ice formation in a delivery pipe to smoothly perform liquefied carbon dioxide delivery work.SOLUTION: A liquefied carbon dioxide delivery facility comprises: a tank capable of storing liquefied carbon dioxide; a delivery pipe penetrating the inside and outside of the tank toward an upper part from a lower part, and for delivering the liquefied carbon dioxide in the tank to the outside of the tank; a pump provided in the delivery pipe, and for sending the liquefied carbon dioxide in the tank to the outside of the tank; and a pump control unit for controlling the pump so as to decrease the rotation speed of the pump as the liquid level of the liquefied carbon dioxide in the tank decreases, on the basis of the liquid level of the liquefied carbon dioxide in the tank.SELECTED DRAWING: Figure 6
【課題】払出配管内のドライアイス生成を抑え、液化二酸化炭素の払出作業を円滑に行う。【解決手段】液化二酸化炭素の払出設備は、液化二酸化炭素を貯留可能なタンクと、タンクの内外を下方から上方に向かって貫通し、タンク内の液化二酸化炭素をタンク外に払い出しする払出配管と、払出配管に備えられ、タンク内の液化二酸化炭素をタンク外に送り出すポンプと、タンク内の液化二酸化炭素の液面高さに基づいて、タンク内の液化二酸化炭素の液面高さが低下するにつれて、ポンプの回転数を低下させるように、ポンプを制御するポンプ制御部と、を備える。【選択図】図6
