Compressor models in calculations

There are different options on how to utilise compressor models in the calculations within the ENERGY_USAGE_MODEL section in INSTALLATIONS. Three different options will be illustrated here:

No matter the compressor model type, it can either be placed in two sections, which can be:

  • Under the CONSUMERS section under GENERATORSETS. This is applicable for electrical motor driven compressors where electricity is generated in de-coupled gas turbines and distributed to the individual process units.
  • Under the FUELCONSUMERS section. Here it is necessary for the compressor model to be coupled to a gas turbine model. The coupled turbine is solely driving the compressor system to which it is attached to.
