Denitrification L2
Created Wednesday 15 October 2014
Basic model of a desulfurization component build up from a flue gas cell and a replaceable model for a denitrification reaction
1. Purpose of Model
The model is used as a basic model to simulate an ideal denitrification facility with fixed separation rate.
2. Level of Detail, Physical Effects Considered and Physical Insight
2.1 Level of Detail
Referring to Brunnemann et al. [1], this model refers to the level of detail L1 as it applies steady state balance equations and simplified characteristics.
2.2 Physical Effects Considered
- Conservation of Mass
- Conservation of Energy
- Reverse flow
- Heat Transport due to convection
- Pressure loss due to friction
2.3 Level of Insight
Heat Transfer
• ControlVolumes:Fundamentals:HeatTransport:Generic HT:Adiabat L2
• ControlVolumes:Fundamentals:HeatTransport:Generic HT:IdealHeatTransfer L2
• ControlVolumes:Fundamentals:HeatTransport:Generic HT:Constant L2
• ControlVolumes:Fundamentals:HeatTransport:Generic HT:CharLine L2
Pressure Loss
• ControlVolumes:Fundamentals:PressureLoss:Generic PL:NoFriction L2
• ControlVolumes:Fundamentals:PressureLoss:Generic PL:LinearPressureLoss L2
• ControlVolumes:Fundamentals:PressureLoss:Generic PL:QuadraticNominalPoint L2
Geometry
- Cylinder geometry : Generic geometry
3. Limits of Validity
- Steady flow.
- Fixed control volume.
- Averaging assumption violated.
- The equations imply that the outlet states equal the states in the balance equations - Not true for large volumes and high gradients.
