The disadvantages of raw biomass are the high value of moisture and oxygen in biomass, low value of energy density, bulk density, high formation of biomass ash and indefinite availability of sustainable biomass resources for production of biofuels. Torrefied biomass has more energy density and hydrophobic which is superior quality for handling and storage. The objectives of this research are to develop a simulation model of the torrefaction process from Malaysian biomass and perform optimization for yield and energy consumption, and to integrate optimal torrefaction process into the existing biomass-based power plant. Suitable biomass resources were selected to become feedstocks for the torrefaction process. After considering several factors mainly the cost and abundancy resources in Malaysia, empty fruit bunch (EFB) from palm oil mill was selected. There are two objective which will be the focus of this which is: to model and optimize torrefaction process from empty fruit bunch (EFB) for different structural configuration; and to integrate the optimal option with the existing biomass-based power plant for retrofitting purpose. The process was simulated using ASPEN Plus. Introducing torrefaction process to existing operation can solve clinkering issue as torrefaction remove moisture and mineral that causing clinker to form and reduce the maintenance cost to remove clinker manually. Torrefaction also will reduce the amount of solid fuel required to produce similar energy production due to its higher energy density. After EFB and other component is defined and properties method is selected depending on the process, the simulation model was developed by using model palette installed inside ASPEN to produce the desired torrefied EFB. For the base model of the simulation, crusher is used for size reduction, two separators and three RStoich model reactors are used for combustion and RYield model reactor for torrefaction. For optimization of mass yield and overall energy consumption, 6 option (simulation model 0 to 5) of design configurations were analysed. For the integration of torrefaction process into biomass power plant, the best simulation model considering the overall energy consumption and mass yield was selected and further studied. Mathematical formulation and selection of the optimal torrefaction process for the minimal energy consumption and mass yield are done by using GAMS software. Jengka Advance Renewable Energy Plant (JAREP) current feedstock cost to energy production is RM 7,000 / MWh and energy consumption at 1.4 MW can be reduce by introducing torrefied pellet fuel into their existing operation. Modification has been made to the torrefaction simulation before integration with biomass power plant. Drying is an energy and capital-intensive process; therefore, the energy cost can be reduced by utilizing low grade heat like flue gas. Thus, 5 options (simulation option a to e) were constructed to further reduce the energy consumption of the total plant operation in the biomass power plant. The option was selected by lowest energy consumption, lowest integration cost and lowest annual utilities cost, therefore Option b was selected to be the best option considering the parameter selected. For integration cost, Option b has the lowest cost at RM 824,540.80 not including the distance from the flue gas source when Option d has the highest integration cost at RM 2,357,757.80. Other than lowest integration cost, Option b also has the lowest energy consumption and annual utilities cost at 1.37 MW and RM 2,587,891.30. introducing Option b into existing JAREP plant will reduce their feedstock cost to energy production to RM 6,705.83 / MWh and energy consumption at 1.344 MW.20aFaculty of Chemical and Process Engineering TechnologyxDissertations 0aUniversities and collegesxDissertations 0aTheses
