Methanol injection

01/12/2008 2:44 AM

Hi everybody

I know that methanol is injected to prevent hydrate formation in a plant; but are there other reasons that methanol is needed to be injected?

thank you

~Heita~

Hi Heita,

You really need to give more information for us to be able to answer!

If you give DETAILS of the process, we will be better equipped to give a good answer. Methanol has numerous process uses, but what the uses are depend on the process.

As one of my bosses used to say "You can never have too much information" .

I've been using methanol to mill nanoparticles, does it absorb water? What do you use it for?

methanol is injected into the engines of race cars, it make an excellent motor fuel.

But, you have to be careful (adding to motorbike fuel tank can give you 1 wild ride)

Also has adverse affects with Aluminium heads, the exhaust is cleaner too.

Methanol is sometimes injected into waste water treatment works where there is biological treatment. It gives the bugs some nutrients.

unlike ethanol, methanol is quite poisonous and should never be in domestic water.

Depending on the water content and other impurities in natural gas, hydrates are formed when the gas is depressurized (dP > 500 psig) to below the hydrate/ice formation temperature after the letdown station. Adding methanol will lower the hydrate formation temperature. This is the only reason I know of for adding methanol in natural gas.

Methanol can be used as chemical reagent, solvent, antifreeze and drying agent. As chemical reagent it can be part of a mixture to produce a final product, such as the making of methyl acetate. As solvent, it can be used to separate chemicals of a mixture from other liquid insoluble to methanol. As antifreeze, it is used to decrease the freezing point of liquids and as drying agent, it is used to absorb water from a gas matrix.

i have been experiment with alternative fuels additives to use in my motorcycles to get alittle extra horsepower once i have them dosed there is no going back to running it on regular fuel anymore its not the same now i have found a new additive that i use. ive not seen much on wear problems unless you are having to ride in a formation with about 50 other motorcycles stop and go with long period of idling then you have problem with over heating and melting ring but then again i have made my on rings for the bike which are thinner.but they sream as long as you dont put more than a quart to 2.5 or 3 gal tanki will give you a hint to what what im running now on stock motor nitromethgasahol!!!! imagine that one it screams.i had to use this form because i have had problems with people trying to add stuff into my tanks at night when im asleep thinking that they could keep me from riding.that is just like using isopro rubbing alcoholyou have problem when you try to start using 50% then it has too much impurities to burn correctly. this is TriFlame

Of course, methanol burns at much richer mixture than gasoline does, between 5.0:1 -6.0:1. Nitromethane is more efficient and expensive than methanol. If you found the right ratio. Good for you, just be careful with your fuel system configuration.

i understand about the ratios i just do it by feel because it wont run on pure or i would probably try it the only thing that you really have to watch out for is to make sure there is no rubber pieces in the fuel system

Yes, rubber and other elastomers are attacked by alcohols.

You should consider setting up an injection system. You could use a 100% denatured alcohol injection, just make sure you get a pump that can handle 100% alcohol. All you need is a small tank, 60-150 psi pump, atomization nozzle, check/one way valve, brass fittings for pump and nozzle, fuel hose, activation switch, and wiring incidentals depending on your bike's power supply. You can obtain various grades and sizes of high pressure fuel line depending on your alcohol pump, EFI fuel line capable of running alcohol, or stainless braid aero hose. Make sure to use EFI clamps or Aero fittings and not cheap hose clamps. You will also want a thick plastic tank with a no flame guard valve mounted away from heat sources on the bike. If you mix the ratio of 40/60 or 50/50 alcohol to water you will reduce the risk of flame-up and get the added benefit of longer combustion cycles. The alcohol is cooling your intake charge and adding volumetric expansion to the fuel charge but the water will increase the burn time of the fuel. You should lean the fuel/air ratio out, and advance the timing manually until you get a healthy burn. A 1gph mist nozzle will give you 30min of spray with a 2 quart tank. The most expensive items will be the pump and the fittings/valves/nozzle, about $160 + tank, line and electrical components. You will have the power on tap, and you can enjoy riding without a hot fuel mix. And you can fill you tank with windshield wiper fluid, or mix your own denatured alcohol and distilled water. You can run pure but you will need to keep tabs on your AF ratio, and on a carb bike that will be tough without the right equipment. (Mount the nozzle on the underside of the intake prior to the TB or carbs).
