    • PROBLEM TO BE SOLVED: To reduce the inconvenience of a conventional system and decrease the power consumption of a regasified lNG terminal. SOLUTION: A compressor-evaporator system for liquefied gas contained in a tank (1) is provided with at least one high pressure pump (26), a turbine (29), and a central electric machine (11) capable of being used in a motor mode or a generator mode in addition to devices (4 and 4') for evaporation by heat-exchange and a device for conditioning gas and transferring it to a pipe line (200), and a motor driven turbo pump (5) containing a rotary assembly on a common axis. The high-speed rotation of the rotary assembly for the pump (5) at 12,000 rpm or more is carried out. The whole inside of the pump (5) is immersed in the same low temperature fluid as liquefied gas contained in the tank (1). A power circuit (12) connected to an electric work (13) controls the central electric machine (11) into the motor mode or the generator mode. COPYRIGHT: (C)2006,JPO&NCIPI
    • 要解决的问题:为了减少常规系统的不便,并降低再生的lNG终端的功耗。 解决方案:包含在罐(1)中的用于液化气体的压缩机 - 蒸发器系统设置有至少一个高压泵(26),涡轮机(29)和中心电机(11),能够 除了用于通过热交换进行蒸发的装置(4和4')以及用于调节气体并将其传送到管线(200)的装置之外,还可以使用电动机模式或发电机模式,以及电动机驱动的涡轮泵(5) )在公共轴上包含旋转组件。 执行用于泵(5)的旋转组件在12,000rpm或更高速度下的高速旋转。 泵(5)的整个内部浸入与罐(1)中所含的液化气体相同的低温流体。 连接到电动工件(13)的电源电路(12)将中央电机(11)控制到电动机模式或发电机模式。 版权所有(C)2006,JPO&NCIPI
