hydrocarbons petroleum

Crude oil or petroleum pumped out of an oil well, is a viscous and complex mixture of several hydrocarbons and small amounts of other compounds. It is not useful in this state. The 'refining of (crude) petroleum' involves the process of fractional distillation, whereb..

Sources of Hydrocarbons - Until the early years of the nineteenth century, only the plants and animals were the known sources of organic compounds. With the advent of the Industrial Revolution in Europe, fossil fuels like coal and petroleum gained prominence as the sources of or..

Petroleum is brought to the surface by drilling a hole in the Earth's crust and sinking pipes deep down through the impervious cap rock. Natural gas first comes out under high pressure. Then, petroleum is pumped out, collected in tanks and transported, for further processing. ..

Coal and Petroleum - Fossil fuels, like, coal, lignite, petroleum and natural gas are non renewable natural resources. Both have an organic origin and are called hydrocarbon fuels. Coal was formed in nature as a solid from the remains of the trees buried deep inside th..

A hydrocarbon is the name given to the mixture of gases caused by the incomplete combustion of fossil fuels. These comprise of paraffins, olefines and aromatics that are emitted from petroleum refineries. Some of these substances are suspected carcinogens, such as the polynucle..

It is believed that coal in nature was formed from the remains of the trees buried inside the earth some 500 million years ago. Due to the bacterial and chemical action on the wood, it got converted into peat. Then, as a result of high temperature and high pressure inside the earth peat got transf..
