Distillation (Stage I)
The Distillation (Stage I) is a machine which processes Crude Oil into Heavy Oil, Medium Oil, and Sour Water, which has applications in the production of Sulfur for Rubber and Category:Fertilizer. When combined with the Distillation (Stage II) and Distillation (Stage III) machines, they allow for the creation of Naphtha and Fuel Gas. All three units can be built direct together in a line with no tiles in between without loss of efficiency or they can be built independently and piped together if so desired. The primary disadvantage of the Distillation (Stage I) and its companion machines is a significant increase in the difficulty of designing the refinery layout, piping, and subsequent byproduct management.
Basic Distiller efficiency comparison
The Coal requirement to process Crude Oil in the Distillation (Stage I) is initially decreased by about 6.25% (0.33 Coal/Crude Oil vs 0.31 Coal/Crude Oil). However, once the Boiler (Gas) is unlocked via the Gas Combustion research, the Coal requirement can be removed entirely if refinery byproducts are used to produce the input Steam Hi instead. It also does not create Waste Water, nor Exhaust as a direct byproduct though handling the byproducts will create some amount of Air Pollution.
