anything made from an advanced circuit, which is a lot of things). blue belts, rocket fuel), and very little petrol-based products (e.g. A valid case is if you want to produce giant amounts of oil-based products (e.g. Now for my opinion: There is almost no good reason to have excess petrol. Oil processing can be super fun to figure out, because it is challenging. If it stops working, try to figure out the root cause and fix it. Imported blueprints (designing your own (even if it's ugly) is always more fun in my opinion)ĭesign it yourself. You also do not need "heavy oil burners" or "light oil burners" to discard your excess heavy or light oil. solid fuel production for the purpose of discarding petrol). "Petrol burners" - places to "burn off" your excess petroleum (e.g. Specific ratios of oil processing : heavy oil cracking : light oil cracking Things you do not need (but can use if you want): If you follow these tips, you should never end up with excess petrol or light oil blocking your pipes. The ratios of these plants will affect throughput, but a "bad" ratio will never result in excess petrol/light oil if you obey the previous bullet point.
#Factorio oil crack
Then, simply create more oil refineries and cracking plants, but always obeying the previous point (only crack heavy/light oil that you don't need for other products). If you need more petrol, first check that you have sufficient crude oil (or coal, if using coal liquefaction). While you can often avoid excess petrol/light oil by carefully choosing oil refinery:cracking ratios, these are difficult to anticipate (given ever-changing product needs), and do not actively prevent excess petrol production (things go wrong when balances change). The important thing is that you only crack heavy/light oil when none more is needed for your oil-based products (e.g. There are many ways to "prioritize" fluid outputs to specific places, but a simple one is to use a pump to pump fluid toward its priority destination, while allowing the remaining fluid to flow passively through pipes toward cracking. To ensure you always have light oil available, prioritize the output of light oil toward production of light oil products (e.g. To ensure you always have heavy oil available (per Point 1), prioritize the output of heavy oil toward the production of heavy oil products (e.g. You can still use basic oil processing, but you must not produce excess petrol, per Point 3. Point 1 means that you will need to use advanced oil processing or coal liquefaction, which are the only ways to get heavy and light oil.
In order to produce heavy oil, you must not have excess petrol or light oil blocking the pipes.įrom these points, a few guiding principles: In order to produce light oil, you must not have excess petrol blocking the pipes. You cannot convert petrol back into heavy or light oil, nor light oil back into heavy oil. No matter how much light oil you have, you can always convert it to petrol. No matter how much heavy oil you have, you can always convert it to light oil. The basic chain of oil processing is: heavy oil -> light oil -> petrol. You don't need to predict the ratios, but know that you will need some amount of each. In late game, you need all three oil products: heavy oil, light oil, and petroleum gas. There are many ways to avoid these problems, but I argue that you only need to understand three basic points to avoid the vast majoritythat you will encounter: excess petroleum gas, excess light oil, insufficient petrol). Many issues can arise which do not have obvious causes or solutions (e.g. Once you crack, you can't go back: only crack heavy/light oil that you don't need. TL DR: You need never have excess petrol, light oil, or heavy oil.
