Claims (5)
- 液化ガスの収容設備から前記液化ガスが送液される送液流路に、前記液化ガスから生じた気化ガスを吸引するエジェクタを備えることを特徴とする気化ガス再液化設備。
- 前記エジェクタの前記液化ガス送液方向下流側に、気液分離機を備えることを特徴とする請求項1に記載の気化ガス再液化設備。
- 前記気液分離機が、
本体容器と、
前記本体容器に収容される前記液化ガスの液面である本体容器液面位置より上の位置で前記本体容器に接続する、前記本体容器液面位置より上の空間に存在する気化ガスを前記収容設備へ送出する送気ラインと、
前記本体容器液面位置より下の部分に設けられた、前記エジェクタからの前記液化ガスを前記本体容器に導入する導入口と、
前記導入口より下の位置で前記本体容器に接続する、前記本体容器内部に収容される前記液化ガスを前記液化ガスの需要設備へ向けて送出する送液ラインと、を備えることを特徴とする請求項2に記載の気化ガス再液化設備。 - 液化ガスの収容設備から前記液化ガスが送液される流路を備えた液化ガス設備において、当該流路に設けられたエジェクタに前記液化ガスから生じた気化ガスを吸引させ、前記液化ガスと前記気化ガスとを接触させて前記気化ガスを再液化することを特徴とする気化ガス再液化方法。
- 前記エジェクタの前記液化ガス送液方向下流側に設けられた気液分離機により、前記エジェクタから送出される液化ガス内に残留する前記気化ガスを前記液化ガスから分離させることを特徴とする請求項4に記載の気化ガス再液化方法。
