SPECIALIZED OIl REFINERIES
I experienced and read too much about factories becoming a mess once oil needed to be processed. The hassle of keeping a balanced oil circuit due to 3 products leaving the refineries at once (or not at all) is just not that much fun for some of us.
This mod introduces 1 new type of refinery, a specialized one. It has to be researched which you are allowed straight after researching oil. It also introduces 3 new recipes, specialized in a single type of crude oil processing. The output is the same for all 3 outlets; a single product.
Water + Crude oil -> Petroleum
Water + Crude oil -> Heavy oil
Water + Crude oil -> Light oil
The specialized refinery is an advanced building. It requires a standard refinery plus some extra materials to manufacture. However, it is less polluting than a standard refinery and is able to produce more in less time. Perfect for a neat, and optionally high demand, production.
