modelMethanatorSystem_L4

Information

1. Purpose of model

This model is based on the Methanator model and is basically only expanded by a dryer-model such that the product gas stream has sufficient properties to be fed in the natural gas grid according to DNVGW G 260/262.

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

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. Consider that using the heatPort will allow a simplified simulation of the heat Flow but will neglect the temperature level of the heat.
