This refinery functions a lot like a big refinery,
It vaporizes the oil and condenses the vapor into usable diesel.
The problem is that waste motor oil has already been refined once
into motor oil. Re-refining it again presents heating, condensing
and filtering problems.
HEAT: If you heat waste motor oil to hot you
get what we call "tar" in the final product. If you don't
heat it enough all you have is a waste oil heater and no diesel.
This refinery uses it's own oil to fire the burner and all of the
heavy byproducts burn with no visible smoke.
CONDENSING: The condenser in this system is key
because it takes a lot of one to do the job. If it's to small you
loose you diesel in the form of vapor into the atmosphere. Both
diameter and length are important.
FILTERING: Filtering is probably the most important
part of the puzzle and the part we spent the most time perfecting.
You get a pretty dirty product out of the refinering process and
cleaning up the final product was "JOB ONE" as far as
we were concerned.
When the refinery is running and up to temp. it
is generating somewhere around 500F to 700F. This heat can be used
to heat a shop or piped in to heat anything.
The aluminum tanks
are storage for the diesel made. We run our Cat loader, Cat tow truck
and our 2004 Duramax on our diesel only and have logged hundreds
of hours between them.
