  • 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 ...
  • Area targeting and storage temperature selection for heat recovery loops

    Walmsley, Michael R.W.; Walmsley, Timothy Gordon; Atkins, Martin John; Neale, James R. (AIDIC Servizi S.r.l., 2012)
    Inter-plant heat integration across a large site can be achieved using a Heat Recovery Loop (HRL). In this paper the relationship between HRL storage temperatures, heating and cooling utility savings (heat recovery) and ...
  • Assisted heat transfer and shaft work targets for increased total site heat integration

    Walmsley, Timothy Gordon; Atkins, Martin John; Tarighaleslami, Amir Hossein; Liew, Peng Yen (AIDIC, 2016)
    Total Site Heat Integration (TSHI) provides a valuable framework for practical integration of multiple energy users. Previous studies have introduced the idea of utilising process heat recovery pockets to assist TSHI. ...
  • Axial Variations and Entry Effects in a Pressure Screen

    Atkins, Martin John (The University of Waikato, 2007)
    Pressure screens are used for contaminant removal and fibre length fractionation in the production of pulp and paper products. Axial variations and entry effects in the screen are known to occur and these variations have ...
  • California’s Renewables Portfolio Standard (RPS) requires 33% renewable electricity generation by 2020 - Dream or Reality?

    Walmsley, Michael R.W.; Walmsley, Timothy Gordon; Atkins, Martin John (SDEWES, 2014-09-20)
    Progress on California’s Renewable Portfolio Standard (RPS), which requires 33% of all retail electricity sales to be served by renewable energy sources by 2020, excluding large hydro, is reported in this paper. The emerging ...
