Optimisation of cogeneration system and fuel inventory with automated targeting model.

Industrial wastes can be used as alternative fuel sources for the substitution of fossil fuel if they contain good calorific values. Through waste-to-energy (WtE) pathway, energy can be harvested from industrial waste through combined heat and power (CHP; or commonly known as cogeneration) scheme. The latter is recognised as an efficient way to supply thermal and electrical energy simultaneously for process plant usage. In this work, cogeneration potential of an industrial waste of glycerine pitch is analysed. A mathematical technique based on process integration, known as automated targeting model (ATM) was extended to optimise the cogeneration and fuel inventory system simultaneously by considering single- and multi-period planning with varying fuel supply. A case study involving glycerine pitch from a palm refinery is demonstrated for the extended ATM. [ABSTRACT FROM AUTHOR]
