How Petrol, Diesel and Kerosene Are Made from Oil

How Petrol, Diesel and Kerosene Are Made from Oil Crude oil may look like nothing more than a thick, black liquid, but inside a modern refinery it is transformed into the fuels that power cars, trucks, ships and aircraft. This video explains how refineries separate crude oil into different fractions through controlled heating and fractional distillation. It explores how rectification columns use differences in boiling points and molecular size to separate petrol, kerosene, diesel and heavier fuel oils, while carefully balancing temperature, pressure, vapour flow and liquid levels inside enormous steel towers. The video also explores the more advanced stages of oil refining, including vacuum distillation and catalytic cracking. You’ll learn why heavy fuel oil cannot simply be heated to extremely high temperatures, how reducing pressure allows valuable heavy fractions to be recovered, and how cracking breaks large hydrocarbon molecules into smaller and more useful fuels. From aviation kerosene designed to remain stable at extreme altitudes to modern refining systems that maximize fuel production, this is a detailed look at the physics, engineering and chemistry behind the fuels that keep modern civilization moving. #OilRefinery #CrudeOil #Petroleum #Fuel #Petrol #Diesel #Kerosene #Engineering #Chemistry #HowItsMade
