Hello Eong and Keith addision Thank you for your keen interest about the more discussion of biogas here in yahoo biofuel group , which our small research group in Brasil also believes too have good green future , in addition to bio oil and bidiesel of real energy economy where as H2 will be the virtual one using this real energy carrier .The simple bioreactor can also recover energy from waste of urban , agricultural and animal of alltypes , including the glycerine and ester , if properly designed.
Our group is designing biodigester horizontal rectangular tanque WITH locally made bricks or sand ciment blocks, covered rectangular plasic sheet suported by plastic nets all housed under rectangular wooden box, all to making use of local materials and manpower. The gas generated can be compreesed and put in gas cylinder of cooking gas, all are available in all the place of Brasil. The solid resdiues are fermented aerobically after milling using seleted strain of fungus to accelerate composting using little urea, then the composted materials are solubilzed using bacterias grown with the solution of the out put of the biodigesters. THIS TWO STAGE BIOLOGICAL PRETREATMENTS CAN BE EASILY IMPLEMENTED TO MAKE FUEL FROM BIODEGRABLE SOLID RESIDUES , AGRICULTURAL, URBAN AND ANIMAL WASTES. The compressed biogas can easily suppliment with biodisel and bioiol made from bimass in rural areas.This can be aapropriate ecological solution under developing stage by our small research groups. Technical colaborations are welcome to make our research sucess. Our project has finished the design stage, will be soon implemented and operated both de biogas and together with biooil project of lower cost for small scale power generations.In addition we wish to make biodeisel from bio oil from wood. Thanks again our group leader,to make our group one of the best working group of biofuel, who really move the discussion in correct directions for real world problems.I also feel that this group is doing a lot to make deveoped countries technical experiences to developing one to make great green future for biofuel and all our group members to sd Pannirselvam Two reactor in batch operations need tecnical skill, when one is not operating , other need to be cleaned and charged with raw materials, T Keith Addison <[EMAIL PROTECTED]> wrote: Hello Eong and Pannirselvam Could you provide a description of the technologies you're using? I'd welcome more discussion of biogas issues and technologies - we do have it, but not enough, IMO. Very much on-topic here. Recent discussion on the composition of "natural gas" (LPG) and other sources of methane came close. We've discussed these before, among others - bag digesters: http://www.ias.unu.edu/proceedings/icibs/ibs/info/ecuador/install-polydig.htm How to install a polyethylene biogas plant http://www.fao.org/WAICENT/FAOINFO/AGRICULT/AGA/AGAP/FRG/Recycle/biodi g/manual.htm Biodigester installation manual Are your units similar? Re locally available raw materials, I wonder what could be adpated to serve the purpose of a polyethylene bag... When you see something like this it seems anything's possible! http://www.manalagi.com/jamesplace/indonesia/sopi/index.html Culture Corner Archive: Makin' Moonshine > Our university research group situated in the the city o Natal, >Northeast of Brazil ina na under developed area of Brazil, >different than the economically developed area of the south of >Brazil , under my coordination have technical resource for the >new low cost design for biogas from solid residues regarding >inovative design..We wish to lend helping hand to have joint >effort to solve the problems there and our research students wish >to lend the helping hand also to you. > I thank the leader of this biofuel group , who does a lot to >bring the people all over the world and do very seroius work and >wish to thank all of them related to biofuel for the very serious >work.
