和文要約和文要約等以下本編抜粋:1. 実証事業の内容及び成果等 本事業は、インドネシアの製糖工場から排出される廃糖蜜(モラセス)から燃料用エタノールを製造するものであり、製造されたエタノールは、ガソリンと混合され自動車用燃料として使用され、化石燃料であるガソリンの一部を代替する。インドネシアの重要産業である製糖工場の収益構造の改善と近代化を促すものであり、インドネシア政府が現在推進中の燃料用エタノール政策を加速するものでもある。本事業がインドネシア製糖工場の設備近代化・経営近代化のモデルケースとなることでインドネシア国内においても燃料用エタノール事業が広く普及することを目的とする。
英文要約Title: Model Project for Ethanol Production from Molasses in a Sugar Factory (FY2010-FY2012) FY2010 Annual Report
In this model project, bioethanol will be produced from molasses generated in the sugar production process. The project will add value to sugar cane as a renewable energy resource, and simultaneously improve the profitability of the sugar factory. The ethanol from molasses production process involves a technique developed in Japan called repeated batch fermentation method with agglomerated yeast. The employed yeast has the characteristic of being agglomerated and settles after the fermentation period. It can be utilized repeatedly through several fermentation batches. The fermentation process is as follows. The molasses and agglomerated yeast are fed into the fermentation column; fermentation is carried out for 48 hours. During the fermentation period, the yeast gradually settles to the bottom of the column, and finally the broth (the fermented liquid) is separated from the agglomerated yeast in the column. After the broth is discharged to the evaporation unit, a fresh batch of molasses is again fed into the column as the feedstock for the next batch. The agglomerated yeast stays in the column after the broth has been separated. This agglomerated yeast can be utilized for up to ten batches. After ten batches have been completed, the yeast/mud sludge is discharged into a separator unit. The ethanol recovered in the unit is returned to the evaporation process, and the dewatered sludge is discharged and utilized as fertilizer, animal feed, etc. The ethanol plant will be constructed at Gempolkrep factory of PTPN X, Japan and Indonesia will cooperate carrying out this model project such as demonstration operation. This model project from FY2010 to FY2012 has these works as follows; 1.Site Survey/Concluding the Implementation Document, 2.Design work, 3.Equipment Fabrication/Transportation, 4.Supervising for Installing/Operation, 5.Demonstration operation, 6.Dissemination. In FY2010, we carried out these works from 1. to 3. 1.Site Survey/Concluding the Implementation Document; We started to conclude the implementation document just after singing the minutes of understanding. It took more time than anticipated to sign the implementation document due to adjusting schedules and opinions among many authorities concerned as per Indonesian request to make them involved. Finally we concluded the implementation document in late March. 2.Design work; We had already submitted the basic drawings to PTPN X such as piping & instrument diagram, plot plan and loading data. As per these drawings, PTPN X had just started their work. 3.Equipment Fabrication/Transportation; We had already placed orders of a part of Japanese scope equipment. And we will place the rest of them in FY2011. There is a possibility that delivery time of some equipment will be delayed due to the east Japan earthquake. In case delay delivery has occurred, we will have meetings about revising the master schedule.
