    • A cryogenic fluid pumping and vaporization system utilizes a heat engine to drive a cryogenic fluid pump, a coolant pump, a lube oil pump and a dynamometer, the cryogenic fluid pump and the coolant pump being driven through a hydraulic drive system, while the lube oil pump, hydraulic pump and the dynamometer are mechanically driven by the engine. Operation of the coolant pump and cryogenic fluid pump flows coolant fluid through a coolant flow circuit and flows cryogenic fluid through a cryogenic fluid flow circuit, each of these two circuits being operatively connected to a process fluid heat exchanger which transfers coolant heat to the cryogenic fluid to vaporize it. Heat from the hydraulic drive system and a lube oil flow circuit associated with the lube oil pump is transferred to the coolant flow circuit via suitable heat exchangers interposed therein. Exhaust gas heat generated by the engine is also transferred to the coolant through an exhaust gas heat exchanger. The dynamometer is connected in parallel with the coolant flow circuit to receive a selectively variable throughflow of coolant to thereby selectively vary its load on the engine and selectively vary the total heat transferred from the engine to the coolant. Heat generated within the dynamometer is transferred directly to the coolant, and the dynamometer load may be varied without altering the cryogenic fluid pumping load borne by the engine.
    • 低温流体泵送和蒸发系统利用热力发动机来驱动低温流体泵,冷却剂泵,润滑油泵和测力计,低温流体泵和冷却剂泵通过液压驱动系统驱动,而润滑油 泵,液压泵和测功机由发动机机械驱动。 冷却剂泵和低温流体泵的操作使冷却剂流体流过冷却剂流动回路并使低温流体流过低温流体流动回路,这两个回路中的每一个可操作地连接到过程流体热交换器,该过程流体热交换器将冷却剂热传递到低温流体 蒸发它。 来自液压驱动系统的热量和与润滑油泵相关联的润滑油流动回路通过插入其中的合适的热交换器传递到冷却剂流动回路。 由发动机产生的废气热也通过排气热交换器传递到冷却剂。 测力计与冷却剂流动回路并联连接以接收冷却剂的选择性可变的通流,从而选择性地改变其在发动机上的负载并选择性地改变从发动机传递到冷却剂的总热量。 在测力计内产生的热量直接转移到冷却液中,并且测功机负荷可以改变而不改变发动机承受的低温流体泵送负荷。
