Crude

das Schmiermittel der Weltwirtschaft

Key indicators for Middle Eastern medium-sour crude, such as Oman and Dubai contracts, are rallying too.¹⁾

• heavy crudes are denser (contain larger hydrocarbon molecules) ¹⁾
• light crude yield more high value lighter products (gasoline) ²⁾
• Light crude is more valuable than heavy because it’s less expensive to refine and has higher energy content
• Light sweet barrels can be refined into mostly only gasoline
• we need heavier crude to produce distillates that we need to keep the economy running. (ie fuel oil, jet fuel etc)

Every country produces different crude grades, this is why global oil flows are so important. (from newspaper article)

• No. of crude oils in the world: > 400
• crude oils traded on a significant scale: approx. 100

When it comes out of the ground, oil is knovvn as crude oil and is a mixture of petrochemical and other components, such as sulphur, sand and some waten that need to be removed or reduced beíore the refining process. ³⁾

Crude oil price changes can cause wide swings in refining margins because they’re the main feedstock of refineries. Petroleum product prices are sticky—it can take weeks for changes in oil prices to work their way into petroleum product prices. ⁴⁾

Diesel, jet and marine fuel are more easily made from the heavy crudes hailing from Russia and the Middle East than from lighter varieties such as U.S. shale oil, which is bet- ter suited to making gasoline.

C2H4 is more reactive than C2H6 because the latter is an alkene.it is unsaturated compound and its pi bond are easily available for the reaction.
