Abstract: A pump for pumping a cryogenic liquid includes a pump housing defining an elongated cylinder. An elongated piston slides within the cylinder so that an intermediate fluid chamber, that is configured to receive an intermediate fluid, is defined within the cylinder adjacent to a first end of the piston and a fluid pumping chamber is defined within the cylinder adjacent to a second end of the piston. The fluid pumping chamber includes an inlet and an outlet. The pump housing is positioned within a sump. The sump is configured to receive and submerge a portion of the pump housing within the cryogenic liquid and to provide cryogenic liquid to the inlet of the pumping chamber for pumping. A sump jacket surrounds the sump so that a sump insulation space is defined therebetween. A pump jacket surrounds the pump housing so that a pump insulation space is defined therebetween.

Abstract: A probe assembly for determining a saturation pressure of a liquid includes a manifold having at internal passage and an elongated bulb defining a chamber and having a distal tip portion and a proximal portion. The bulb is secured to the manifold at the proximal end portion with the chamber in fluid communication with the internal passage. A charging port is selectively in fluid communication with the internal passage of the manifold. A pressure transmitter is configured to detect a pressure within the chamber of the elongated bulb.

Abstract: A cryogenic fluid fueling system includes a first container configured to contain a first cryogenic liquid with a first headspace being positioned above the first cryogenic liquid. A heat exchanger vaporizes a portion of the first cryogenic liquid such that pressure within the first container is raised as vaporized cryogen moves into the first headspace. A second container is configured to contain a second cryogenic liquid with a second headspace being positioned above the second cryogenic liquid. A condensing coil is positioned within the second headspace of the second container and fluidically connected to the first interior of the first container such that a portion of the first cryogenic liquid is propelled into the condensing coil and is warmed to provide a first cryogenic vapor.

Abstract: An integrated cryogenic fluid delivery system includes a tank adapted to hold a supply of cryogenic liquid and having an end wall. A shroud is positioned on the end wall and contains a shell and tube heat exchanger. The heat exchanger includes a shell defining a warming fluid chamber and having a shell inlet and a shell outlet in fluid communication with the warming fluid chamber. A number of cryogenic fluid coils are positioned within the warming fluid chamber and are in fluid communication with a cryogenic fluid inlet port and a cryogenic fluid outlet port. A fuel shutoff valve has an inlet in fluid communication with a liquid side of the tank and an outlet in fluid communication with the cryogenic fluid inlet port of the heat exchanger. A manual vent valve has an inlet in fluid communication with a headspace of the tank and an outlet. The fuel shutoff valve and the manual vent valve each have a control knob that is accessible from the first or second side of the shroud.

Abstract: A dosing vessel includes a reservoir having an inlet and an outlet and is configured to contain a supply of a cryogenic liquid with a headspace above. The outlet is configured to be connected to a dosing arm having a dosing head. A low pressure sensor is configured to detect a vapor pressure in the headspace. A high pressure sensor is configured to detect a pressure in a bottom portion of the reservoir. An inlet valve is in fluid communication with the inlet of the reservoir and is placed in communication with a source of cryogenic liquid. A controller is in communication with the high and low pressure sensors and the inlet valve and is configured to store a preset liquid level or a preset differential pressure corresponding to the preset liquid level, to determine a measured differential pressure based on data from the high and low pressure sensors and to control the inlet valve based on the measured differential pressure and the preset liquid level or the preset differential pressure so that a liquid level of a cryogenic liquid stored in the reservoir is generally maintained at the preset liquid level.
