Synthesis ofintegrated Bio-Refinery

By Kok Hock Lee

Abstract

There is no doubt that the major challenge that industrial processes are facing is in terms of economic aspect. Economic aspect such as market condition or operating cost is forcing the changes in quantities and qualities of desired products. With this, it showed the necessity for indust1y to reassess the production technologies or to initial the new production paths which can bring more profit for the industry. Hydrocarbon is the essential energy resource for the current world. With the depletion hydrocarbon reserves and the increasing of the hydrocarbon prices, industries start to shift the focus into bio-based resources to replace the dependency of the current economy in the hydrocarbon. Besides that, the productions of the hydrocarbon-based product have followed with several environmental issues. A lot of improvement had been suggested and applied, bio-refinery is one of the emerging core idea. Bio-refinery is defined as a processing facility which converts the biomass into valued product such as liquid transportation fuels. This study covers the technologies that available in bio-refinery and the process flow sheets for each technology. The objectives of this study are to create the available database of biomass process technologies and come out with the most profitable process flow of the biorefmery. The major issue that led to the less interest of the industry in bio-refinery is in terms of its economic value. With the availability of bio-mass feedstock, bio-refinery will be the major player in the future industry especially in terms of renewable energy. In the bio-re.finery, the processes involved are anaerobic digestion, fermentation, gasification and pyrolysis. Different process will have different end products and led to different profits generations. This is the main function of the research to optimize the profit that generated from the integrated bio-refinery using the modeling via GAMS software. From the results, it is justified that, when integration carried for both thermochemical and biochemical processes, it will provided the average profit. For biochemical conversion, it provided much lowest profit compared to the integration process. In the other hand, the thermochemical conversion will result in highest profit than the average profit generated by integration process
