[Tagging] Tagging oil refineries

[Bert -Araali- Van Opstal]

Yes they are refineries, I was involved in the construction of several 
of them. The oil from the biological source (feedstock) is refined by 
removing gums from energy seeds and pyrolysis of solid biological 
feedstocks (wood, agricultural waste etc...). To a non professional they 
might look similar but the processing equipment and production process 
is quite different. The oil is produced from energy seeds, mostly palm 
oil and in moderate climate areas sunflower seeds and field mustard are 
quite common, from which the gums or even a certain refined residue 
might be used for post-processing for food and pharmaceutical purposes. 
The product term here is bio-oil, not editable oil, as most of the oil 
is no longer regarded suitable for human consumption.
Since the example you have given is next to a petroleum refinery, we can 
be pretty sure it's bio-oil for mixing with petroleum oil, as is a legal 
requirement (minimum required percentage of bio content) in many 
countries, f.i. most countries in the European Union.

Editable oil might also be refined, not just olive oil, also other oil 
obtained from seeds. What distinguishes them from typical bio-oil 
refineries is that the main purpose is producing fats and oils for use 
in food and pharmaceutical (think also about cosmetics). The seed shells 
from the crushing and pressing process is mostly provided as feedstock 
for the production of animal feeds or again, production of bio-oil 
through pyrolysis. In a bio-oil refinery, a crushing and pressshop might 
be present, the residue, if economically viable mostly also converted to 
bio-oil by pyrolysis or, if economically less interesting, again as 
feedstock for production of animal feed (mostly in a different 
facility). The editable oil facilities not only appear on a small scale 
(like you would tag with craft) but also on a large industrial scale 
(typical f.i. palm oil based).
Editable oil facilities, as far as I know don't use pyrolysis. They do 
have reactors though to refine oil. Again they might look similar then 
the bio-oil facilities.

I would suggest to use product = oil as according to our wiki, for all 
industrial scale bio-oil or editable oil production facilities. Small, 
artisanal facilities could by tagged with craft tags if you wish.
For petroleum refineries , their products range from bitumen for asphalt 
production, light and heavy fuel and gasses for fuel and plastics 
production, lubrication products: Product=petroleum as for all petroleum 
derived products.
