oil and gas petroleum

It is the most important of the fossil fuels. Petroleum occurs under the Earth's crust. It is believed to have formed due to the bacterial action of decomposition on marine animals and prehistoric forests inside the Earth, under conditions of high temperature and pressure. Petroleu..

Oil spill is a major problem in the oceans and seas. The oil tankers and offshore petroleum refineries cause oil leakage into the waters. This pollutes the waters. Oil floats on the water surface and prevents the atmospheric oxygen from mixing in t..

. Coke is an important reducing agent is another by-product containing 98% carbon. Petroleum is often referred to as liquid gold, due to its importance as a fuel in transportation (Petrol, Diesel, kerosene, gas oil, fuel oil) and as a source of over hundred a..

Butane with small quantities of ethane and propane. These gases can be liquified under pressure and bottled in cylinders. By itself LPG is odourless. On leakage, it is toxic if inhaled. It also forms an explosive mixture with air. LPG can be hazardous if handled carelessly.A strong smelling c..

Coal and petroleum have organic origin, being decomposed plant and animal matter buried deep inside the earth. Coal is mined like any other mineral. The chief coal producing countries in the world are China, U.S.A., U.S.S.R., U.K., Germany, Poland, Australia and India. In India, coal is ..

Natural Gas - It is a mixture of gaseous hydro-carbons. It is found usually along with petroleum deposits. Natural gas consists mainly of 85% methane, 10% of ethane and 3% of propane and butane. It may also contain nitrogen, oxygen, carbon di-oxide and hydrogen sulphid..

. These caps allow the lighter vapors to escape up the column while the progressively less volatile and heavier fraction condense and flow into the respective trays (through tray holes and overflow) in the lower section of the tower. They can then be tapped out. The major products obtained from the..

In countries, where coal is easily available as compared to the rapidly depleting petroleum and natural gas, it is possible to avert the energy crisis by preparing petroleum and natural gas artificial..

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 distillati..

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 organic comp..
