TRANSCRIPT
Processing facilities in a palm oil processing complex
(POPC) are owned by different owners, each with
separate economic interests
Fuzzy optimisation approach is adapted to address the
multi-objective optimisation
The optimum network configuration which addresses
individual interest of owners is determined

ABSTRACT
INTRODUCTION
Industrial symbiosis (IS)
mutual exchange of materials and energy between
industrial plants
Palm oil processing complex (POPC)
consists of palm oil mill (POM), palm oil refinery
(POR), palm oil-based biorefinery (POB), combined
heat and power (CHP)
promotes the utilisation of palm-based biomass
enhances the interaction in palm oil industry
Fuzzy Optimisation
Integrates the multiple objectives into a single
parameter in a model1,2
This paper presents a systematic approach for
synthesis and optimisation of integrated POPC based on
IS concept, where conflicts of interest of each
participant are considered.
80 t/h fresh fruit bunch (FFB)
is fed into POM
MILP model is solved via
LINGO v10
Optimisation Model
Objective: Maximize λ
Subject to:
mass balances of POM, POR,
POB and CHP
energy balances of POM,
POR, POB and CHP
economic calculations
payback period ≤ N years

ACKNOWLEDGEMENT
CONCLUSION & FUTURE WORK
Detailed allocation of
material and energy of
POPC that mutually satisfied
by each owner is analysed
and optimised
Disjunctive programming is
adapted to palm oil
industrial cluster in future
work
Optimum solution is obtained
Maximum net present value
(NPV) over 15 years
operational lifespan of POM,
POR, POB and CHP are 13.38,
29.04, 20.58 and 14.86
(USD/million), respectively
0.15 MW excess electricity is
exported to nearest grid
