Oil processing

< Oil processing

Oil processing is a large part of Factorio. It was introduced in v0.9. Oil processing may refer to the researched technology, the recipe used in the Oil refinery, or the overall workings of oil.

Mechanics & Usage

To extract, process and use oil and its connected products, research, as shown above, is needed.

Overview

File:Example-Oil-Refining.png

Crude oil being drilled and refined.

File:Example-Oil-Cracking.png

Oil being cracked into lower forms.

File:Example-Oil-Usage.png

Oil being used to create plastic and batteries.

Pumpjacks need to be placed on top of the middle of the oil well. Given electricity (90kW, upgradeable), Pumpjacks will produce a certain amount of Crude oil per second, shown on the right, at the bottom of the information panel. Over time this value will decrease down to a minimum of 0.1 oil/s, providing infinite oil at a very low rate.

All liquids can be transported by Pipes, only Crude oil can be filled into Barrels and moved with the Railway network or other vehicles.

The Crude Oil then needs to be refined in an Oil refinery. The Oil refinery also needs Power provided by an Electric network. It has a much higher demand, at 420kW, but it is also upgradeable. The oil refinery needs to have a recipe set (see above for available recipes). Once it is set, the inputs and outputs show what needs to be, and what will be supplied. You cannot move the locations of these, only rotate the entire machine. Make sure that the products have somewhere to go (preferably Storage Tanks), as the refinery will stop production of all products if one product output is full.

Now you have the three basic products. Heavy Oil, Light Oil and Petroleum Gas. Both Heavy Oil and Light Oil can be cracked to the next lower type in a Chemical plant (recipe above). This is useful if you've got lots of Light Oil, but are lacking in Petroleum Gas (A common problem).

From here, after some research, you can use the oil products to create various products. They are all listed above.

Tips

• Lubricant
  • If you run your Heavy Oil pipe from the refineries past a Lubricant-making Chemical Plant before sending it to the cracking Chemical Plants, you can be sure that the Lubricant production will have priority over cracking.
  • Most games will only ever need one lubricant-producing Chemical Plant and one Storage Tank for the lubricant.
  • Since Lubricant is only used for blue belts and electric engines, and the only other use of Heavy Oil is flamethrower ammo (production of which is either best placed in your oil refinery or elided entirely) and cracking into Light Oil (the Heavy Oil to Solid fuel production ratio is terrible compared to cracking it first), you may want to consider placing your production of robots and belt assembly nearby your oil refineries, so lubricant doesn't need to be sent as far.

Advanced

Optimal ratio to produce petroleum gas

The optimal ratio is the ratio of buildings in which they can all work without jamming or having inactive superfluous. For example, when you apply 1 Oil Refinery to the optimal Advanced oil processing ratio [5 : 1 : 7], you get [1 : 0.20 : 1.4]. Round that up to get [1 : 1 : 2], which means:

• 1 Oil Refinery on Advanced oil processing
• 1 Chemical plant on Heavy oil cracking
• 2 Chemical plants on Light oil cracking

The setup above will not jam, but it will have temporarily inactive buildings. If you round down, it will no longer have inactive buildings, but it will jam (over time).

This can be sped up with modules, but to prevent jams or inactive buildings, it is recommended to speed everything up evenly. When slowing down (by using Productivity modules) you are better off experimenting on altering the ratio or the speed on certain buildings, since these ratios are only mathematically correct if all the buildings have the same speed, and have 100% productivity (so no added bonuses).

Calculating the optimal ratios is relatively challenging, since not all of the durations of the processes are the same (the crafting speed of a chemical plant is 1.25, but the refinery's is 1.0). If this were not taken in account, it will lead to (temporarily) inactive buildings, which is not optimal.

Crude oil transport

File:Pumping station.jpg

Autonomus installation for manual pickup of Crude oil barrels.

Since oil fields practically can deplete, new sources will be demanded. There are many different ways to overcome this problem:

• Pipes/Belts
• Manual pick-up
• Trains
• Robots (Troublesome over long distances)
