Processes and systems for monitoring and controlling refrigeration energy comsumption

A method for monitoring and controlling energy consumption of a refrigeration system operatively connected to a plurality of production trains, the method comprising:

• using a monitoring system,
• initiating a control logic configured to control a production control system pertaining to the refrigeration system,
• wherein the plurality of production trains includes a production flow therethrough,
• wherein each of the production trains respectively comprises a primary compressor comprising a first recycle valve;
• for each production train:
• obtaining a plurality of production parameters, wherein one of the plurality of production parameters comprises a production flow rate;
• determining whether the production flow rate is less than a production threshold;
• calculating, using the plurality of production parameters, an isentropic efficiency value for the primary compressor if the production flow rate is less than a production threshold;
• comparing each of the plurality of isentropic efficiency values;
• determining from the comparing each of the plurality of isentropic efficiency values, a primary compressor having a lowest isentropic efficiency value,
• wherein the lowest isentropic efficiency value is one of the plurality of isentropic efficiency values that is quantitatively smallest compared to all other isentropic efficiency values;
• selecting the respective primary compressor having the lowest isentropic efficiency value;
• and
• using the production control system:
• reducing the production flow to the one of the plurality of production trains which includes the selected primary compressor;
• redirecting the production flow from the one of the plurality of production trains including the selected primary compressor to at least one other of the plurality of production trains;
• opening the first recycle valve of the selected primary compressor to fully opened;
• and
• shutting down the selected primary compressor.
