M OTIVATION

      T HE PLANT
      400 MW power plant with 50 MW (LHV) of H2 with 90% CO2 capture
      using coal as the fuel.


                Most capture plants are associated with large energy penalty
                (~10%) - decreasing their economic viability.
                Efficiency is the one of the most important factors when
                selecting and designing plants with CO2 capture.

      A IM
      Explore opportunities for energy integration in an IGCC plant for
      improving the efficiency using Heat Exchanger Network Synthesis
      and an integration of tools.

                Simultaneous MINLP methods let math considerations
                define the decomposition
                The Sequential Framework decomposes the problem into

      GTP RO
      GTPro from Thermoflow Inc. is used to model the power island.
      GTPro is particularly effective for creating new designs and
      finding their optimal configurations. To this end, it has a library
      of gas turbine models that replicates real performance.
      Initial HRSG design and marginal costs for HP, IP & LP steam
      are derived from GTPro.

      GAMS
      General Algebraic Modeling System (GAMS) is used for
      modeling and optimization of the Heat Exchanger Network.

                An integration of methodologies and tools for the energy
                integration of a combined hydrogen and electricity is presented.
                The HENS methodology presented lead to designs with
                improved efficiency.


      The methodology provides multiple designs with same efficiency and
      similar costs but with varying degrees of complexity to enable the
      engineer to select an integration scheme based on qualitative
      parameters such as operability etc.

      This work carried out by NTNU in the Dynamis IP project under the Sixth Framework Programme. Dynamis project
      aims at developing technologies for hydrogen and electricity co-production based on fossil fuels with 90% carbon
      capture rate.

I NTRODUCTION M ETHOD AND T OOLS I NTEGRATION C ASE S TUDY S UMMARY S UMMARY An integration of methodologies and tools for the energy integration of a combined hydrogen and electricity is presented. The HENS methodology presented lead to designs with improved efficiency. The methodology provides multiple designs with same efficiency and similar costs but with varying degrees of complexity to enable the engineer to select an integration scheme based on qualitative parameters such as operability etc. This work carried out by NTNU in the Dynamis IP project under the Sixth Framework Programme. Dynamis project aims at developing technologies for hydrogen and electricity co-production based on fossil fuels with 90% carbon capture rate.
