Title (EN) PRESSURIZING SYSTEM
(FR) SYSTÈME DE PRESSURISATION
(JA) 昇圧システム
Abstract:
(EN) A pressurizing system 1A according to the present invention is provided with: a cooling temperature adjusting unit 9A which employs the flow rate of a supplied cooling medium to adjust the temperature of an intermediate supercritical pressure liquid generated by being cooled by a main cooling unit 31 upstream of a pump unit 4; and a pressure detecting unit which detects an inlet pressure P1 of the intermediate supercritical pressure liquid on an inlet side of the pump unit 4 and detects an outlet pressure P2 of a target supercritical fluid on an outlet side of the pump unit 4. The cooling temperature adjusting unit 9A is characterized in that the flow rate of the cooling medium is controlled on the basis of a pressure difference between the inlet pressure P1 and the outlet pressure P2, or a pressure ratio between the inlet pressure P1 and the outlet pressure P2.
(FR) Un système de pressurisation 1A selon la présente invention est pourvu de : une unité de réglage de température de refroidissement 9A qui utilise le débit d’un milieu de refroidissement distribué pour ajuster la température d’un liquide sous pression supercritique intermédiaire généré en étant refroidi par une unité de refroidissement principale 31 en amont d’une unité de pompe 4 ; et une unité de détection de pression qui détecte une pression d’entrée P1 du liquide sous pression supercritique intermédiaire sur un côté d’entrée de l’unité de pompe 4 et détecte une pression de sortie P2 d’un fluide supercritique cible sur un côté de sortie de l’unité de pompe 4. L’unité de réglage de température de refroidissement 9A est caractérisée en ce que le débit du milieu de refroidissement est régulé sur la base d’une différence de pression entre la pression d’entrée P1 et la pression de sortie P2, où un rapport de pression entre la pression d’entrée P1 et la pression de sortie P2.
(JA) 本発明の昇圧システム1Aは、ポンプ部4の上流において主冷却部31で冷却、生成された中間超臨界圧液体の温度を、供給する冷却媒体の流量によって調整する冷却温度調整部9Aと、ポンプ部4の入口側において中間超臨界圧液体の入口圧力P1を検出するとともに、ポンプ部4の出口側において目標超臨界流体の出口圧力P2を検出する圧力検出部と、を備える。冷却温度調整部9Aは、入口圧力P1と出口圧力P2の圧力差、又は、入口圧力P1と出口圧力P2の圧力比、に基づいて、冷却媒体の流量を制御することを特徴とする。
