System, method and apparatus for the regeneration of nitrogen energy within a closed loop cryogenic system

An apparatus for using nitrogen in a closed loop cryogenic system, comprising:

• a cryochamber having a first nitrogen flow line, the first nitrogen flow line having a first nitrogen flow line inlet for connection to a nitrogen source and a first nitrogen flow line outlet, at least two cryogenic cooling loops, each of the at two cryogenic cooling loops each having a nitrogen inlet in fluid communication with the first nitrogen flow line and a nitrogen outlet in fluid communication with the first nitrogen flow line, the nitrogen entering through each of the nitrogen inlets having the same temperature, each of the nitrogen outlets of the at least two cryogenic cooling loops being located, along the first nitrogen flow line, downstream of all of the nitrogen inlets and upstream of a turbo expander, all of the nitrogen inlets being positioned upstream of all of the nitrogen outlets, the at least two cryogenic cooling loops each having a heat exchanger through which the nitrogen flows, the heat exchanger having a fluid inlet for introducing fluid to be cooled into the heat exchanger and a fluid outlet for discharging the fluid cooled in the heat exchanger;
• the turbo expander having a turbo expander inlet in fluid communication with the first nitrogen flow line outlet and a turbo expander outlet in fluid communication with the nitrogen source, the turbo expander re-cooling the nitrogen that passes through the first nitrogen flow line and the at least two cryogenic cooling loops;
• and
• at least one storage tank in fluid communication with the fluid outlet of the heat exchanger of the at least two cryogenic cooling loops.
