The Refinery building converts Crude Oil to Diesel . Crude Oil is produced by Oil Wells and needs to be transported to a Refinery in order to be converted into Diesel . This is used to produce Diesel Tokens . The Refinery is an Era III building, therefore when transitioning from the Steam Era to the Early Diesel Era several Refineries will appear in random locations across the map.
The base unit of the Refinery consumes 2 Crude Oil and produces 1 Diesel every Game tick. There are three extensions that can be added to the Refinery, two of which increase the conversion of Crude Oil to Diesel. The Propane plant extension adds a new process to the Refinery that converts Crude Oil into Goods and Money tokens . With all extensions added to a single Refinery, it will consume 8 Crude Oil while producing an average of 6 Diesel , 0.67 Goods and 0.67 Money tokens every Tick.
The base production process for the Refinery is shown below:
|Image||Extension||Consumes||Produces||No. of Ticks to Complete||Building Tile Size|
|3 Crude Oil||2 Goods + 1 Diesel Token||3 Ticks||2x1|
|3 Crude Oil||2 Diesel||1 Tick||2x2|
|2 Crude Oil||2 Diesel||1 Tick||2x1|
