What is meant by refining of petroleum for Class 8?
The process of separating crude petroleum oil into more useful fractions is called refining. The refining of petroleum into different fractions is based on the fact that the different fractions of petroleum have different boiling point. The refining of petroleum is carried out in an oil refinery.
What is petroleum refinery by Brainly?
petroleum refinery is an industrial plant where crude oil is made into useful petroleum products by distillation and other processes.
What is meant by refining of petroleum and how is it done?
Petroleum refineries change crude oil into petroleum products for use as fuels for transportation, heating, paving roads, and generating electricity and as feedstocks for making chemicals. Refining breaks crude oil down into its various components, which are then selectively reconfigured into new products.
What is the main purpose of refining petroleum?
What is the main purpose of petroleum refining? Petroleum refining is mainly aimed at transforming crude oil into useful goods such as LPG, gasoline, jet fuel, diesel oil, jet fuel and fuel oils.
What is the principle of refining petroleum?
The principle which is used is that the longer the carbon chain, the higher the temperature at which the compounds will boil. The crude petroleum is heated and changed into a gas. The gases are passed through a distillation column which becomes cooler as the height increases.
What is the chemical formula of petroleum?
WHAT IS PETROLEUM? The cycloalkanes, also known as naphthenes, are saturated hydrocarbons which have one or more carbon rings to which hydrogen atoms are attached according to the formula CnH2n.
How do we process petroleum?
Petroleum refining separates crude oil into components used for a variety of purposes. The crude petroleum is heated and the hot gases are passed into the bottom of a distillation column. As the gases move up the height of the column, the gases cool below their boiling point and condense into a liquid.
How is petroleum formed in nature?
Petroleum is a naturally occurring liquid found beneath the earth’s surface that can be refined into fuel. … Petroleum is formed when large quantities of dead organisms–primarily zooplankton and algae–underneath sedimentary rock are subjected to intense heat and pressure.
Why is petroleum called black gold?
The Petroleum is called black gold because when the crude oil is extracted from the soil below, it is black in colour. … But after the purification of black crude oil, it gives golden colour.
