Methane Generation From Vegetable Waste

high temperature steam will reform any organic material into syn-gas, a mixture of compounds, mostly hydrogen, carbon monoxide, carbon dioxide, methane and other light hydrocarbons. Also, burning with limited oxygen will do the same thing. This is related to the process that is used by Siemens in a unit that has been used in Germany for the past 30 years and is well proven. For more information, see Siemens Gas Generator. Also, you should see syngas wiki, too. Additionally, human, animal and kitchen waste can be anaerobic digestion to produce methane and carbon dioxide gas at a ±60%-40% ratio. These processes are discussed in more detail in the article "My Earthbound Space Station". The article is in about 60% complete and more details are to be forth-coming.

Last weekend here in the UK a large vegetable warehouse caught fire, this fire was fed by the large amount of methane that was produced by rotting vegetables. Saddly 4 firemen lost their lives in the blaze. Spencer.

India is the home of the technology you are looking for. It would likely need to be scaled up for your purposes. Track down ARTI in Pune.

If you have trouble finding them get back to me.

Good Luck!

Okay. Your company might want to explore licensing technology from DuPont - US or M&G - Italia, or B&V - US; if you really want the latest and greatest.

Dear Sir,

Just saw your posting. I realize this question was from November 07 but, did you ever find the information you were seeking ?

Were always interested in this subject, as we work in the renewable energy and construction business in America and are interested in any new ways to bring our cH4 into a better grade of bio-methane and as close to L. N. G. Liq. Nat Gas, purity as is possible. It is better for the equipment and ICE motor operations.

For vegetables I have read, that to be producing consistently one needs the additions to the fray of some brown matter, such as field grasses dry leaves , perhaps grain product additions such as raw feed and/or fine cut woody - cellulostic input, just to create a balance in the microbiology of breaking down of the matter.

Have you studied Jean Pain's work ?

He's done quite well with just woods clippings from his forest, all placed in a particular configuration, order and amounts with a tank inside the mound to process Methane . Its really quite a nice system.

For the cleaning up process, we believe that depending upon the end use of course and the source of the digestate perhaps 1st an Iron sponge method for H2S removal and 2nd a double water column for Co2 removal with a final refrigeration stage to remove H2O and then compression to about 30 bar in Liquid form is perhaps the least expensive processes that we know of. We would like to find more simple less expensive ways if they are there. There must be thousands of ways I've read about to cleanse cH4 but each one is complicated or requires costly products and methods that is except for the process I have described . It is a 1 , 2 , 3 or 4 step process depending on the final need and the minor power requirements can be met by the cH4 on hand.

Well , if you do have the time drop me a line - always wanting to learn more.

Best

Joe

i am searching about the technoligies regarding urban solid waste.i want to know about the PLASMA TECHNOLOGY which are recently in use.can u help me about the working of this tech.and also about the installation of a plant of capacity 5MW.

THANKING YOU!

This is a reply to Georgia Adobe and everyone one who has replied to the question. If you look at the USA Department of Energy you will find that the making of CH₄ or any other short chain hydrocarbon for use as a fuel or other feed stock requires a multitude of steps, most of which are well known and well documented. There is also a need to consider the effects this conversion will have on the environment in the future. Even the world's economy must be considered. We are wise to take the time to fully engineer the uses of all the technology for this conversion. This would include considerations of the economies, safety, and ecology, The is a CR4 project which is organizing to do just this. If you have not done so already, then I suggest you examine the CR4 blog for the APIX project. The international organization for the APIX project is ongoing and we do thank the CR4 administration for its support and help with this project. There is plenty of time for you to join this project, it cost nothing but some of your time. We need to recruit not only engineers, but an attorney with international law and patent law experience would be quite helpful. The APIX project is a part of the bigger picture of sustainability engineer which is being studied by the CR4 administration and may be added to the CR4 Sections. Please look at this and join in the effort to help solve some of Earth's major energy problems.
