Abstract: A pressurization and evacuation system is provided, including a top 3-way valve including a first port, a second port and a third port, a bottom 3-way valve including an first port, a second outlet port and a third port, and an educator including a pressure inlet, a suction inlet, and a discharge outlet. Wherein: a first conduit fluidically connects the top 3-way valve third port with the educator pressure inlet; a second conduit fluidically connects the top 3-way valve second port with the bottom 3-way valve first port; a third conduit fluidically connects the bottom 3-way valve third port with the educator suction inlet; and a fourth conduit fluidically connects the bottom 3-way valve second port with a customer apparatus.

Abstract: A method of pressurization and evacuation of a system including during a pressurization phase; introducing a pressurized gas stream into the top valve, which is actuated to direct the pressurized gas stream into the bottom valve, wherein the bottom valve is actuated to direct the pressurized gas stream to the customer apparatus; and during a vacuum phase; introducing the pressurized gas stream into the top valve, which is actuated to direct the pressurized gas stream into the inlet port of the pressure inlet of the educator, thereby producing a low pressure condition in the suction inlet, introducing a customer gas stream into the bottom valve, which is actuated to direct the customer gas to exit the bottom valve, wherein the low pressure condition causes the customer gas stream to be directed to the educator suction inlet, wherein it mixes with the pressurized gas stream and exits the educator discharge outlet.

Abstract: A reactor liquid cool down method is provided. The method includes obtaining a warm recycle stream (102) from a reactor (101) and compressing the warm recycle stream (102), thereby producing a compressed warm recycle stream (104); cooling a compressed warm recycle stream (104) with a controlled liquid cryogen stream (110) in a heat exchanger (107), thereby producing a cool recycle stream (112), wherein the cool recycle stream has a mean fluid temperature, monitoring the mean fluid temperature and comparing the mean fluid temperature to a predetermined control valve set point, thereby defining a temperature deviation; modulating a temperature control valve (109) to vary the controlled liquid cryogen stream (110) in order to produce a temperature deviation that is less than a predetermined value, and returning the cool recycle stream (112) to the reactor (101).

Abstract: A fuel management method for long term stationary truck use is provided. This method includes a truck with at least a first saddle tank or a second saddle tank integral to the truck. Each saddle tank has a fuel level sensor to measure the fuel level. A fuel trailer provides supplemental fuel, and a fuel pump downstream of the fuel trailer and upstream of the truck pressurizes the fuel from the fuel trailer. The method includes supplying fuel to local users from saddle tanks, activating the fuel pump when the fuel level of both the saddle tanks is less than a first predetermined threshold, thereby transferring fuel from the fuel trailer to the first saddle tank and the second saddle tank, deactivating the fuel pump when the fuel level of either the saddle tanks is greater than a second predetermined threshold.
