LPG as a catalyst with wmo

[tight_as]

Has anyone had any experience with running gas as a catalyst for burning waste engine oil? Thoughts / experience etc....?:confused:

[kerrynzl]

Can you explain your motive here?
You dont need LPG to clean burn oil, Just oxygen!!

The hotter the oil gets , the cleaner it burns.
LPG wouldn't be a catalyst, it would be an additional fuel requiring more oxygen / air to burn [ combined with the oil.]

:cool:my motive is to only use straight wmo without cracking it.
i would filter it thorught 3 or 4 diffrent stage filters and maybe cut it 10% with diesel in the winter.
i would use lpg as a little bit of a helping hand. i would probably start on normal diesel and swicth to the good oil . i have a toyota dyna which i put a 6.2 lt chev diesel just as a work truck and to get wood in and am sick of paying for fuel i also have a toyota 80 series t/d i will also run the good oil/fuel in :cool:

[kerrynzl]

Three words of advice!! Filter , Filter , then Filter.
You won't need lpg just run it on 100% oil [ start it on diesel when cold ]
If you can get the shit through the injectors it'll run sweet [ I have personally done this ]
Make a hot water heat exchanger [ out of a small fire extinguisher bottle etc ] to pre-heat the oil BEFORE it goes through the fuel filter.
Don't listen to the Bullshit about "heavy metals" etc. It is only the hydrocarbons that ignite in a compression ignition engine [ my petro-chemist mate in Oz spent hours explaining all this ]
WMO will not wear out your pump anymore than the bearing surfaces it protects in the engine under high loads [ it is an OIL remember]
If you run a duel fuel Diesel shutdown system for cold starting use one filter for each fuel and a cheap turbo-timer so the engine can purge the pump of waste oil. The smoking everybody claims at idling usually disappears when the oil is preheated.
In Western Oz it's quite warm, you could probably start a diesel on straight oil.
Not like us poor suffering Kiwi's
ps: how do you guys handle the road-tax revenue collectors??

hi thanks for your info kerrynzl. i am an underground fitter so oil is not to hard to get hold of. I would filter the oil through three filters 1 hydraulic 1 fuel/water 1 fuel filter i think that it should be enough maybe.Do you think that i should mix even a little bit of fuel with it? The oil i can get is a mixture of diff eng trans hyd so i might have to start to keep only the eng oil. I am in the process of building a cracking plant but i am sick of paying for fuel as is everyone that is on the forum. I have not had any problems with the transport dept (heavies) as yet but i guess give it time.

The goal here is to run 100% WMO, the secret here is "Heat" to lower the viscosity.
You should keep the Engine oils & trans fluids separate to use 100%.
All the other oils you could blend with "low octane unleaded pump gas" at about 30% gas 70%oil [ this should be thin enough for it to "cold start" ]
With 100% WMO your engine should pick up some power [ about 2 % ] because WMO is about 142,000 Btu/gal vs Diesel at 139,000 Btu/gal
Low grade gasoline is about 125,000Btu/gal so when it is blended 30/70 with WMO the result is about 136,900Btu/gal average so there should be a 2% drop in power.
There are many companies out there are selling Diesel Secrets etc, What they are selling you is the knowledge I have just written here, plus maybe some bag filters and usually their special "magic potion".
The magic potion is Xylene [ or Xylol ] also called "Dimethylbenzene" which is a strong solvent aromatic hydrocarbon.
This is totally unneccessary for blending, except a little bit helps when there is a condensation problem from hydroscopic fluids being present.
The other product being sold is "magic beads" which also performs the same thing and is also sold as "cat litter".
With WMO blending these "snake oils" are not needed.

I'm just bumping this ahead of all those spamming assholes

[tight_as]

whats with the buying pills on line?
tell them if they dont make diesel to get off the forum:mad:

[tight_as]

Thanks Kerrynzl for all the info. Just wondering if you have made a cracking device or r u running straight engine oil?

[kerrynzl]

So far I've designed, and are presently building a 2 pass "firetube" reboiler out of an old propane tank. [ these can hold a bit of pressure ]

I've been developing a burner that will burn all the heavy's from the base of the distillation tower [ so far I've managed to get it to burn oil-sludge from an engine ]
I'm gonna fit a Catalytic converter to the base of the flue-stack, this will burn any unburned hydrocarbons at approx 500c then I'm trying to recover some of the flue temp as an oil pre-heater.

My main concern is keeping the neighbours off my back

Economically you're better off running straight WMO in a diesel [ you lose less than 5% cleaning it ] Distilling oil to diesel only recovers approx 70-80%

[kerrynzl]

Again I'm just bumping this ahead of all those spamming assholes .

Could the moderator / admin please help us by deleting all their bullshit!
[ we'd get more people interested in this forum ]

[tight_as]

have you allready made a smaller plant?
if so have you got some pics. i have toyed with the idea but have got twin boy and girl to keep my spare time filled. i also allready tip all my eng oils from my truck and missus car into my truck after oil changes. i once did an experament with an old landcruiser motor , we ran straight new eng oil in it for about an hour and it seem to like it. also tryed running hyd oil and same result so i dont think i will have too many troubles only the heating thing would be a good idea

Tight as: If you are planning on useing WMO straight, without heat, your success will depend upon which particular engine you are running it through. In my Dodge Ram with the 12 valve Cummins and p7100 inline fuel pump, I have run straight WMO for a couple of years without any problems. My Jeep Liberty with Common rail injection has trouble with blends greater than 50%. The additives in the WMO create deposits of scale on the VGT vanes which causes them to stick and overboost on occasion, so I only use very low blends in it.

In general, the older hydraulically injected systems will handle the WMO without issue, but the newer common rail systems with VGTs are unreliable unless a dual tank heated system is used.

I have finnished putting my 2nd tank on my truck and made a batch of fuel. 90% weo 10% diesel and went for a run. It is only a bit smokie on idle but otherwise all good. I am very happy with the resault. I only put the diesel in as it is in the middle of winter here and a bit chilly in the morning. I will try to take some photos this weekend:cool:

Tight as: What rig are you running your WMO blend in?

[tight_as]

I have a toyota dyna that i put a chv 6.2 ltr out of a hummer in:D

[Unsoxia09]

thanks for the input man...it just gets really frustrating when i see alot of other guys smaller than me pressin more, or bigger guys pressin the same amount. Ill keep liftin hard core and hopefully itll pay off

I have been getting WMO from the local airport. This is a cleaner oil and there is little chance of getting antifreeze or transmisson fluid in the mix.

[Canifa793]

The oil i can get is a mixture of diff eng trans hyd so i might have to start to keep only the eng oil.

yah agreed:D
