A system for initiating the operation of a cryogenic pump wherein the suction line to the cryogenic pump and the cryogenic pump itself are brought to the proper cooldown temperature sequentially using separate temperature-based control schemes.

Cryogenic pump system

System and method for controlling process fluid flow to maintain a set delivery pressure at varying demand, including a fluid-loaded, self-operated main regulator and a method for providing the loading pressure therefor. The system also includes a flow restrictor for metering the loading fluid flow, a back-pressure regulator for controlling the loading fluid pressure, and a temperature-actuated regulator for venting loading fluid when the process fluid temperature varies from a selected range.

Fluid delivery pressure control system

A gas supply system comprising an atmospheric vaporizer and a powered heat exchanger in series each having a rated capacity at least equal to the design gas usage rate.

Method and apparatus for reliable gas supply

A method for ensuring that sufficient liquid is maintained in a liquid reservoir which is distant from a liquid supply station, comprising periodically determining the amount of liquid in the reservoir and sending the periodic determinations to a signal receiver for determination of the actual usage rate of liquid from the reservoir, sending a signal from the receiver to a remote supply station if certain defined mathematical operations indicate that liquid resupply is needed, and sending liquid from the remote supply station to the liquid reservoir.
