Heat exchanger apparatus, manifold arrangement for a heat exchanger apparatus, and methods relating to same

A heat exchanger apparatus comprising:

• a first fluid inlet manifold connectable to at least one first input stream to receive a first fluid at a first fluid inlet of the first fluid inlet manifold, the first fluid having a first temperature;
• a second fluid inlet manifold connectable to at least one second input stream to receive a second fluid at a second fluid inlet of the second fluid inlet manifold, the second fluid having a second temperature that is below the first temperature or above the first temperature;
• a second fluid outlet manifold;
• a first fluid outlet manifold;
• a plurality of heat exchangers, each of the heat exchangers connected to the first fluid inlet manifold, the first fluid outlet manifold, the second fluid inlet manifold, and the second fluid outlet manifold so that the first fluid and the second fluid are passable through the heat exchangers so that heat is transferred between the first fluid and the second fluid so that the first fluid changes in enthalpy and the second fluid changes in enthalpy as the first fluid and the second fluid pass through the heat exchangers;
• the first fluid outlet manifold connectable to at least one first output stream to output the first fluid after the first fluid has had a change in enthalpy via the plurality of heat exchangers;
• the second fluid outlet manifold connectable to at least one second output stream to output the second fluid after the second fluid has had a change in enthalpy via the plurality of heat exchangers;
