Most Resent Research Cell-based dynamic heat exchanger models – direct determination of the cell number and size Petar SabevVarbanov, Jiří JaromirKlemeš, Ferenc Friedler
Heat exchange cell • H=”Hot”, C=”Cold”; • HI=”Hot Inlet”, HO=”Hot Outlet” • CI=”Cold Inlet”, CO=”Cold Outlet” Cell model: icon representation Cell model: detailed picture mH hHI mH hHO QCELL mC hCI mC hCO Assumptions Definition • Perfect mixing in the fluid cells • Constant fluid densities • The tanks are completely full • Constant specific heat capacities • The thermal resistance of the wall is neglected • The wall heat capacity is taken into account • Two perfectly stirred tanks, exchanging heat only with each other through a dividing wall
Cell model of a heat exchanger • A complete heat exchanger can be modelled by a number of cells • The cells are combined to reflect the internal flow arrangement in the exchanger Single-pass (1-1) heat exchanger mHOT, hOUT,HOT mHOT, hIN,HOT mCOLD, hOUT,COLD mCOLD, hIN,COLD

Minimum number of cells Derivation Temperature Heat exchange
Summary on the cell model • Distributed models become inefficient for complex heat exchangers • From the lumped– mostly cell models are employed • The cell parameters need to be carefully estimated accounting for the underestimation of the temperature differences • A method for direct identification of the number of cells has been developed • Mostly applicable to shell-and-tube heat exchangers • A useful visualisation of the cell number identification procedure is provided • The method can be further extended to the other kinds of heat exchangers
P-graph for Process Synthesis Friedler, F., J.B. Varga, and L.T Fan. (1995), Decision-Mapping A Tool for Consistent and Complete Decisions in Process Synthesis, Chem. Eng. Sci., 50(11):1755-1768
P-graph: a Rigorous Mathematical Tool Suite of tools Search space • Axioms for feasible networks • Algorithm MSG • Algorithm SSG 103–106 x • Exploit the problem structure • Much faster • Superior to direct Mathematical Programming
P-graph algorithms:Maximal Structure Generation (MSG) Problem Formulation Reduction part Consistent sets O & M Composition part Maximal Structure • Problem Formulation • set of raw materials • set of products • set of candidate operating units • Superstructure (Maximal) • Union of all combinatorially feasible structures • Rigorous super-structure Legend: O: set of operating units; M: set of materials
ABB Algorithm – Even Faster Search • Employs the “branch-and-bound” strategy • Combines this with the P-graph logic (SSG algorithm) • Ensures combinatorial feasibility Non-optimal decisions are eliminated from the search
Configuration and Setup Demands: 10 MW power and 15 MW heat Power: 100 €/MWh Heat: 30 €/MWh Natural gas: 30 €/MWh Fertiliser from biogas digestion: 50 €/t Plant life: 10 y Case studies Limit the availability of the biomass to 30 MW
Fuel Preparation Options Biomass Gasifier Syngas Filter Biogas digester Performance per unit input Streams / Materials AR: Agricultural residues PR: Particulates BR: Biomass residues SG: Syngas RSG: Raw syngas BG: Biogas CO2: Carbon dioxideFRT: Fertiliser
Energy Conversion Options Fuel Cell Combined Cycle Biogas Boiler Natural Gas Boiler Performance per unit input {F}: Fuels {FCCC} {Q}: steam Steam details {Q}: steam Steam details NG: Natural gas MCFC-GT Q1 P = 1 bar Q20 P = 20 bar BG: Biogas MCFC-ST Q2 P = 2 bar Q40 P = 40 bar SG: Syngas SOFC-GT Q5 P = 5 bar SOFC-ST Q10 P = 10 bar
Results Case 4; Biomass at 10 €/MWh Profit: 5.51 MM€/y Cases 1, 2, 3; Biomass < 18 €/MWh Profit: 10.05 / 6.48 / 6.23 MM€/y Biomass MAX 30 MW
Results Summary • Biomass is profitable over a wide price range • Topologies relatively robust until tipping point • Fertiliser – marginal significance The trade-off between the Agricultural Residues – Natural Gas prices dominates the designs
P-graph for FCCC Summary • Biomass viable for FC • High efficiency lower resource demand • Energy supply and conversion: complex systems • Synthesising : combinatorially difficult • P-Graph: appropriate tool effectively solving the task • Successfully applied to choosing FCCC - based system design
