- bmicraft 10mo agoAren't the proportions is those essentially static?
- pletnes 10mo agoDepends a lot on the oil field, geology is random
- adastra22 10mo agonone of those finished products come out of the ground that way.

- buran77 10mo agoNeither do chips, even if they all start as silicon from the ground. What the earlier comment was saying is that the actual composition of crude oil varies by location so you aren't necessarily getting the same ratio of finished products at the process. With silicon you have a bit more control over what goes into the fab. But you're still at the mercy of demand from the market.
- throwaway48476 10mo agoThe crude composition defines a range of possible products, not exactly ratios. Longer chain hydrocarbons are also cracked to yield more light products.
- buran77 10mo ago> defines a range of possible products, not exactly ratios I'm not sure I follow, varying range necessarily implies varying ratios (e.g. a product missing from the range means its ratio is zero). Even when in theory you can obtain some higher quality products, the composition of the crude can make it too complex and expensive to practically obtain them. You don't want to refine gasoline from heavy crude, especially in winter when demand is lower. For gasoline or kerosene you want to start from lighter crude. Same with many undesired components (either from the crude or resulting from the refining methods), the more you have, the more complex the refining, and the resulting ratio of products you obtain varies. So in practice what you get out of the refining process absolutely depends on the characteristics of the crude, and many other things like market demand or the capability of your refinery. Same as with silicon. The process to make the wafer results in different quality if you want to make low tech or cutting edge semiconductor products.
- pletnes 10mo agoThat way? I was trying to say that the mix of hydrocarbon molecules is different for each and every oil field due to local geological variation. Even within the field, since eg lighter molecules presumably come out first.
- eternauta3k 10mo agoNo, refineries make more heating oil in winter and more gasoline in summer driving season.
- ahartmetz 10mo agoCracking can turn heavier oil fractions into lighter oil fractions. It's a very common procedure.
