  • Application of P-graph techniques for efficient use of wood processing residues in biorefineries

    Atkins, Martin John; Walmsley, Timothy Gordon; Ong, Benjamin H.Y.; Walmsley, Michael R.W.; Neale, James R. (AIDIC, 2016)
    It is anticipated that demand for chemicals and fuel derived from sustainably grown bio-mass will increase over the coming decades. Forest and wood processing residues and waste are likely to become a significant feedstock ...
  • Approximation of non-linear cost functions in p-graph structures

    Ong, Benjamin H.Y.; Walmsley, Timothy Gordon; Atkins, Martin John; Walmsley, Michael R.W.; Neale, James R. (AIDIC, 2016)
    P-graph employs combinatorial and optimisation algorithms to solve process network synthesis (PNS) problem. However, the P-graph framework requires linear cost functions when optimising PNS problems. As a result, a high ...
  • Optimising energy recovery in hydrothermal liquefaction of radiata pine and Kraft mill black liquor

    Ong, Benjamin H.Y.; Walmsley, Timothy Gordon; Atkins, Martin John; Walmsley, Michael R.W.; Neale, James R.; Varbanov, Petar S. (2018)
    The aim of this paper is to develop a heat exchanger network for hydrothermal liquefaction that is co-located with an existing Kraft pulp mill. Hydrothermal Liquefaction (HTL) is an energy-intensive process that operates ...
  • Total site heat and mass integration and optimisation using P-graph: A biorefinery case study

    Ong, Benjamin H.Y.; Atkins, Martin John; Walmsley, Timothy Gordon; Walmsley, Michael R.W. (AIDIC (Italian Association of Chemical Engineering), 2017)
    The aim of this paper is to solve total site heat and mass integration and optimisation using P-graph framework, with a biorefinery case study. Total site heat and mass integration is important for the selection of biorefinery ...
  • Total site heat integration of multi-effect evaporators with vapour recompression for older kraft mills

    Walmsley, Timothy Gordon; Atkins, Martin John; Ong, Benjamin H.Y.; Klemeš, Jiří Jaromír; Walmsley, Michael R.W.; Varbanov, Petar S. (AIDIC (Italian Association of Chemical Engineering), 2017)
    This paper aims to apply Total Site Heat Integration (TSHI) to appropriately integrate Mechanical and Thermal Vapour Recompression with multi-effect evaporators at older Kraft Mills, to cause a step reduction in fossil ...
