Re: [biofuel] Old propane tanks
Thought about that one.The best one I have heard so far, is to get the proper connectors, and hook the 100 lb bottle to the propane grill that came with the house ( I could be grilling for a year with what's left in the 2 100 lb, bottles ) or rent an industrial propane heater and just burn it off. I will admit, those little propane hand torches come in real handy, maybe I could find the connectors and hose to use the big bottle with the little torch. That way I could use the propane to braze the parts together to make the BioDiesel reactor, it is not like I don't have a couple of extra of the 100 lb bottles, LOL.

Re: [biofuel] Old propane tanks
It wasn't the valves, but, the valve covers, they were lightly rusted in place ( couldn't get to the valves ). It is now a non-issue anyway, a little WD-40, ATF, and Elbow Grease, worked just right.

Re: [biofuel] Old propane tanks
Final count, 6 100 lb bottles ( 2 partially filled with propane in them - 3 without valves ), 1 20 lb bottle, 1 30 lb bottle, and 1 40 lb bottle. The last 3 100 lb bottles didn't have valves but one had a valve collar, and were free, the company was retiring them, due only to age, and not due to condition, so they are in great shape, but for the occasional spot of surface rust were the thick coat ( 3-6 layers ) of paint had been chipped through. Most of the bottles don't have valve collars, but one did. The guy that helped me load them told me that they ( the company that I got them from ) would still be using them except for their age and lack of safety features ( like valve collars ), and could still handle the 200+ psi of filling with propane if it wasn't for the company required safety issues as mentioned above. The bottles with out valves have had the valve threads sprayed with a shot of WD-40 and a swipe of ATF, to keep them from rusting any more. The 100 lb bottles are in the backyard, and the 3 small bottles stored upside down at the front of the garage with the garage door up about 2 in for air circulation. The bottles that need it all will be given a coat of metal primer ( and all will be repainted - fuel Red or Kerosene Blue [ Perhaps BioDiesel Green? ] - not sure which yet - and labeled as Not for Propane ) once the loose paint and rust is scraped off. Am I over looking anything at this point?

Re: [biofuel] Old propane tanks
Greg, Bone up on the acid/base process at JTF. Pressurized esterification is the acid side of the process conducted under pressure. It can increase yields enormously when you start to get to the really gnarly feedstocks like brown grease (60-70% + FFAs) from waste traps or just stuff that's been boiling in the hot sun for months. We've picked up two 100# tanks to process the 100% FFAs that accumulate from the glyc recovery process. Started on them some months ago, just not enough time to complete them yet. As for the pressurizing gas, nitrogen would be perfectly sufficient. Any inert gas will do.Whatever's least expensive to you.

The other 2 100 lb tanks, also have the valve covers rusted on them, but, they are empty. The 20 lb tank is standard BBQ grill tank, and the 30 lb tank has 2 threaded holes at the top. For the most part, they have just a light surface rusting, so they are steel, and not aluminum. Even saw some 250 gal tanks, but, I just would not be able fit them, into the back of my Land Cruiser Now I have to find out just what it is going to take to get the valve cover off the non-empty tank, with out turning my self into a fireball.Does anyone have any ideas?

Make sure you have an inlet and outlet on the tank you're welding or cutting on. Connect a flexible hose from the exhaust pipe of the vehicle to one of the inlet holes in the tank you're working on, letting the exhaust flow in and then out the other hole. Run the exhaust for at least 10 minutes (longer for very large tank) before doing any cutting or welding. Run the exhaust the whole time you're working on the tank. What happens is the carbon monoxide in the exhaust combines with any oxygen in the tank to form carbon dioxide, which doesn't support combustion. No oxygen, no combustion, no potential explosion. Using oxy-acetylene, I've cut open tanks and welded tanks containing gasoline, with gas still in the tank with absolutely no problem. Flushing with water and or soap and water for me hasn't worked in the past, where I did have a tank explode. Fortunately, I was fine; just singed my beard.

Re: [biofuel] Old propane tanks
Forgot to mention that if you do attempt pressurized esterifications (100 psi), PLEASE, PLEASE, PLEASE do so by filling all vapor spaces with an inert gas such as CO2 (inexpensive) to reduce the risk of explosions. Compressed air (increased oxygen content) is not a wise choice for such a process.

Re: [biofuel] Old propane tanks
Greg, For both a pressurized esterification reactor at 100 psi or an atmospheric reactor, they should work well. Worlds of difference between the fill pressures of propane and the equivalent of what goes into a bicycle road racing tire. The biggest reason why these tanks aren't recertified or fail certification is that by the time their stand ring starts to rot out the dealer is of the mind that their life cycle is almost up and it's cheaper/easier to replace the tank than to repair/recertify it for only a few more years use. The nice things about these tanks is their dished top and bottom, which allows for good separation of the glycerin cocktail from the fuel layer. You'll probably want to install this tank upside down on a stand so as to gain access for a center mounted circulation/transfer pump. Install two entry ports for oil and methoxide on top. One can be used as a vent when filling to prevent back splashing. Install an insulation blanket and you've got something similar to the hot water tank processors that are being cooked up elsewhere. Propane has a nasty habit of impregnating every pore on the inside of tanks and continually exuding for literally years after a tank has been abandoned. You're right about displacing any gasses with water before cutting. If you have access to a CO2 tank (diverted from a MIG welder?) you can keep a small flow going into the tank so the water level is sufficiently apart from wherever a torch or plasma cutter might be working. That will allow for a quick and clean cut rather than the water pulling heat away as you cut Two of these puppies in line would make a nice acid/base system Todd Swearingen. - Original Message - From: "Greg Harbican" <[EMAIL PROTECTED]> To: Sent: Monday, August 30, 2004 1:06 AM Subject: [biofuel] Old propane tanks > I have a possible source of propane tanks that have failed certification, and, might be able to get one or two at scrap prices.I know to fill them with water to force out any propane than may still be in them, so they don't explode when I go to cut/drill into them.I figure that if I can locate a 40 lb tank, that has failed certification, that it should make a processor that can handle about 20 gal at a time. > > Any advice as to converting them to a BioDiesel processor? > > Greg H. > > [Non-text portions of this message have been removed] > > > > > > Biofuel at Journey to Forever: > http://journeytoforever.org/biofuel.html > > Biofuels list archives: > http://infoarchive.net/sgroup/biofuel/ > > Please do NOT send Unsubscribe messages to the list address. > To unsubscribe, send an email to: > [EMAIL PROTECTED] > Yahoo!

Re: [biofuel] Old propane tanks
Adding an over-pressure release valve couldn't hurt I would say. Labelling the tank as non-propane couldn't hurt either. -- Martin Klingensmith > I have a possible source of propane tanks that have failed certification, > and, might be able to get one or two at scrap prices.I know to fill > them with water to force out any propane than may still be in them, so > they don't explode when I go to cut/drill into them.I figure that if I > can locate a 40 lb tank, that has failed certification, that it should > make a processor that can handle about 20 gal at a time. > > Any advice as to converting them to a BioDiesel processor? > > Greg H. > > [Non-text portions of this message have been removed] Yahoo!

[biofuel] Old propane tanks
I have a possible source of propane tanks that have failed certification, and, might be able to get one or two at scrap prices.I know to fill them with water to force out any propane than may still be in them, so they don't explode when I go to cut/drill into them.I figure that if I can locate a 40 lb tank, that has failed certification, that it should make a processor that can handle about 20 gal at a time. Any advice as to converting them to a BioDiesel processor? Greg H. [Non-text portions of this message have been removed] Yahoo! Groups Sponsor ~--> $9.95 domain names from Yahoo!.
