Re: [Biofuel] disolving lye

[Derick Giorchino]

I don’t let it build up pressure I have the top port open all the time it is hot. The rubber is not to much to wory about I use o rings made of viton both on the shaft seal and the main opening. I also keep the discharge valve closed so it wont siphon out.   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Michael Luich Sent: Monday, October 03, 2005 9:57 AM To: Biofuel@sustainablelists.org Subject: Re: [Biofuel] disolving lye   I have one as well, My concern would be the rubber seals and having anything that dangerous under pressure.

I use them when I keg beer.  The port at the top is for introducing CO2 to seal the lid, for carbonationand to force the beer out the other port for dispensing.      After fermentation and settling, the uncarbonated beer is siphoned into the keg through the removable, clamp-down lid.CO2 is intoduced  --- > pressure to seal the lid. At this point they do not leak. They will leak if there is not adequate pressure inside or if the lid has a bad gasket. The keg is shaken/rolloed on the floor to get the CO2 dissolved.      Could the same system be used to mix and then dispense the methoxide into the processor? It would not even have to be elevated.  The same pressure that seals the lid forces fluid out the dipensing port.     Problems:       -You cannot see if all of the lye is dissolved.       -Remember that the tank is pressurized. Must have a good way of regulating flow (on/off valve). Once the dispensing port is opened (via a pushdown screw-lock attachment) the fluid flows until the pressure is gone or the tank is empty.       Is anybody using these soda kegs for dissolving and dispensing lye?                                              Tom        ----- Original Message ----- From: Derick Giorchino To: Biofuel@sustainablelists.org Sent: Sunday, October 02, 2005 11:06 PM Subject: Re: [Biofuel] disolving lye   Hi there  I have found a good way to mix the methoxide. The process needs some exposure to the methanol at this time. I hope to eliminate this soon. I got a stainless steal soda syrup container on e bay .5 gal cap. It has one port at the top that is above the top limit of the fluide and one port that goes to the bottom of the vessel .  I took out the relief valve and put a ½ '' o ring then a ½'' I D  bronze bushing. I picked up a small paint mixer at the hardware store welded a ½'' stick of round bar to the end of the mixer. After filling the vessel with methanol I add the dose of N.H.O. put the cap on and put the vessel in a large bucket of cold water. With a hand drill on the mixer I mix the stuffing out of the mix. The heat generated is quite enpresseve thus the need for the bucket of cold water. The only draw back at this time is I am doing 120 l batches = 6.35 gal of methoxide. I have been just mixing the max of methoxide and pumping raw methanol to make up the difference so for it seems to work out o.k. I don't know if I can post pictures of this on this sight but if there is any interest I would gladly send picks to those who would like.
