well i have a lot of difficulty to get quotation of equipment such as fermentor tower, distillation column, hydrocyclone, heater, pump and tanks... if you could help me it would be great
If you are not finding some of this by using search engines, then I would look up Mother Jones magazine, and also put bio-fuel technologies and other synonyms into the search engines to keep searching. When you write to Mother Jones and some engineering journals and institutes, ask them the same question. Some of what you want might be more inexpensively constructed from the components, e.g. sheet metal, rods cut to size and machined, and so forth. One creative solution would be to re-use hot water tanks, other tanks which you first, of course, clean and have re-coated on the inside to prevent unwanted chemical reactions. This would require tools such as blow torches, but well. This might be a more complicated way to scheme it. But as I was brain storming this, it occurred to me you could ESTIMATE the costs based on the cost of equivalent sized tanks for other purposes, such as agricultural uses, such as tanks for fertilizer. There is another organization you could network, which is S.E.A.D.S. in Harrington, Maine. If Charley (an old Navy vet who works with self-sustainable tech projects) or someone is still running that, they can refer you to someone who can help you with the answers. Sorry if I haven't been of more assistance. Oh, have you contacted your state university's Agricultural Extension, and Engineering Department?
I would suggest you check out the yellow pages for Houston, TX; Tulsa, OK you will find several manufacturers for heat exchangers, pressure vessels, tanks, heaters and pumps. Assuming you have sufficient definition of each item in terms of size, capacity, surface area, working pressure, materials of construction you should be able to get estimates of just about any piece of equipment you will need. I do not wish to discourage you but, if you don't have a process flow diagram with a heat and material balance for the plant you are going to have a very hard time developing a cost estimate using major equipment cost.
