modelMethanatorSystem_L1

Information

1. Purpose of model

This represents a simplified version of the model 'MethanatorSystem'.

2. Level of detail, physical effects considered, and physical insight

This model contains no detailed physical equations, but mainly consists of a stoichiometric balance for the methanation process. The methanation process can be defined via the parameter 'conversionFactor_H2' which defines the fraction of input hydrogen, that is methanation. With a conversion factor <1 the product gas also contains H2 and CO2 besides CH4 which represents a physically realistic result.

Calculation of Coolant Heat Flow:

Via the parameteres 'useHeatPort' or 'useFluidCoolantPort' a heat port or two fluid ports can be activated to model the needed coolant heat flow. Only one port at a time can be modeled. When using the fluid ports the output temperature can be defined via the input 'T_set_coolant_out'. This temperature will be limited by the technical feasible temperature. This input needs to be activated via the parameter 'useVariableCoolantOutputTemperature'. If not used the temperature of the coolant will be equal to the technical feasible temperature, in this case defined by the parameter 'T_coolant_out_max_set'.
