Oil processing was included in v0.9 to Factorio. It introduced new types of pipes, as well as refinery, chemical plant and several products, a new tech-tree and the handling of liquids.
This is also the reason, why this docs are not complete yet. Please refer to the following pages:
|Pumpjack||Pumpjacks mine the crude oil from the oil spills, and let you carry it by Pipe as seen in the Liquid network/0.9|
|Oil refinery||Refine Crude oil into basic oil products (Heavy-/Light oil and Petroleum gas.|
|Chemical plant||Like the Assembling machine, used to automate processing of liquids.|
|Storage Tank||Stores up to 2500 units of liquid.|
|Small Pump||Allows you to pump liquids from one area to another. Used inline.|
|Pump||Allows you to pump water up from a body of water.|
|Assembling machine 2 Assembling machine 3||Allows you to craft items using liquids, used mainly for Oil barrels.|
|Pipe||Allows transporting of liquids from one location to another.|
|Underground Pipe|Underground Pipe]][[||A Pipe, but under the ground, acting similar to Underground belts.|
Oil Processing: (30 TIME + 1* Science Pack 1 + 1* Science Pack 2)*50 Allows the construction of Pumpjacks, Oil Refinery, Chemical Plant; and also the Basic oil Prossecing for prossecing Crude oil into its derivates (Heavy oil, Light oil and Petroleum gas), and the conversion of those into Solid fuel.
Fluid Handling: (30 TIME + 1* Science Pack 1 + 1* Science Pack 2)*75 Allows the construction of Storage Tank, Small Pump, and the creation, filling and emptying of Barrels. You can use Barrels to store and physically transport 25*Crude oil as a solid item, and later 'unpack' it back into a fluid form in Assembling Machine 2 or Assembling Machine 3. (Only with Crude Oil)
Advanced Oil Processing: (30 TIME + 1* Science Pack 1 + 1* Science Pack 2 + 1* Science Pack 3 )*75 Allows a new recipe for prossecing oil, and unlocks Cracking.
Plastics: (30 TIME + 1* Science Pack 1 + 1* Science Pack 2)*100 Allows construction of Plastic (Intermidiate product)
