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

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


PNS Paradigms: A Comparison


Applying P-graph:Combined Heat and Power using FCCC


Configuration and Setup

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

  • WP 4 (Months 1-24): Design, retrofit and control of intensified heat recovery networks, 9.5 person-months, Tasks 4.1 and 4.3. This will be a development of the P-graph methodology using the ABB algorithm

  • WP 5 (Months 12-24): Putting into practice, 5 person-months, Tasks 5.2 and 5.3


Leader of WP 6 “Technology transfer”

Aim: Effective technology transfer to the wide range academic and industrial communities

  • Validation of the developed novel methodology with the SME partners.

  • Dissemination of the project results, aiming to achieve the best possible project recognition over a broad audience

  • Develop suitable training and support materials for SME partners

  • Establish an active community involving the INTHEAT partners and other users/experts for continuous knowledge management and improvement

  • Runs during months 6 – 24

  • Tasks:

    • 6.1. Technology transfer to SME consortium members

    • 6.2. Dissemination events

    • 6.3. Publications

    • 6.4. Training


Task 6.1. Technology transfer to SME consortium members

  • Streamlined transfer of the developed and acquired technologies, licenses and know-how among the consortium all members

  • A special emphasis will be put on the technology transfer to the industrial partners

    Principles

  • All outputs/deliverables from WPs 1 to 5 will be checked for documentation in such a way, as to enable technology users to obtain reproducible results

  • Additional application procedures may be needed
