英文要約Title : Biomass Energy Technical Study Development / Strategic Development Of Next Generation Technology For Biomass Energy Utilization (Development For Practical Technology) / Research And Development For Cost Reduction Of Main Machinery In The Dry Anaerobic Digestion Technology, And Effective Purification Of Biogas And Practical Use Of Gas Utilization (FY2010-FY2011 ) FY2010 Annual Report
Following are results of research and development for FY2010. 1) Reduction of construction cost and maintenance cost of dry anaerobic digestion facilities: Operation data and cost of existing plant was examined and summarized. For the research of FY2010, the plant was modified and the electricity monitor for feeding equipment was installed, and test program was determined. In addition, the plan of the test method of FY2011 was drawn up. 2) Reduction of hydrogen sulfide from biogas as pretreatment: Hydrogen sulfide concentration in biogas was removed to 36-61% by the addition of suppressant. Quantity of biogas generated was not effected significantly for one month by the addition of suppressant, and any hindrance to fermentation was not observed. 3) A measuring level of the methane density of biogas: Driving time in the past of existing plant and the quantity of change of the biogas was examined and summarized. The device remodeling (above 1) ) for examinations of 2011 was installed. In addition, the plan of the driving method of 2011 was drawn up. 4) Development of effective biogas purification technology which include low concentration of methane: Gas purification unit of 5 m3/h capacity was used. As input gas pressure was higher, methane concentration in effluent gas became higher and recovery of methane became lower. Methane recovery of multiple membrane modules unit was higher than that of a single membrane module. As for the methane recovery, unit entrance pressure got 90% at the time of 0.5MPa. The methane density of this time was 90%. 5) Evaluation of adsorption-type methane storage device: Discussion of the details of the examination was carried out to determine the experimental condition of the gas according to the variation of assumed gas. The document investigation about the biogas use and the rearranging was examined and summarized. The hearing investigation was carried out for Yamaga city gas Co., Ltd. on March 11, 2011, and the hearing result was compiled. 6) A supply examination of the refinement biogas: The document investigation about the off site consumers choice and the rearranging were carried out. In addition, the existing energy infrastructure investigation was examined.
