Crude oil could be refined into many products. For some years kerosene continued to be the principal one. It was sold in grocery stores and door to - door. In the 1880's refiners learned how to make other petroleum products such as waxes and lubricating oils. Petroleum was not then used...
Crude oils are composed of hundreds of different hydrocarbon molecules, which are separated through the process of refining and small quantities of oxygen, sulfur, nitrogen, vanadium, nickel, and chromium. An oil refinery is a group of manufacturing plants that are used to separate petroleum into ...
