Study Notes
Introduction to Coal and Petroleum
- Energy can be extracted and transformed from natural resources as heat or work.
Types of Energy
- Various energy forms exist, each with distinct properties and applications.
Natural Resources
- Derived from the Earth, natural resources are classified as renewable and non-renewable.
Fossil Fuels
- Formed from the decomposition of organic matter, fossil fuels include coal and natural gas.
- Energy in fossil fuels comes from decayed plants and animals over millions of years.
Coal Formation
- Coal is a black fossil fuel used for various purposes.
- Peat, the early stage of coal, consists of partly decomposed plant matter.
- Carbonisation is the process that transforms vegetation into coal under high pressure and temperature.
Types of Coal
- Four main varieties of coal exist, differentiated by carbon content and uses.
Destructive Distillation of Coal
- This process involves heating coal without air, producing by-products:
- Coke: Pure carbon, utilized in steel manufacturing and metal extraction.
- Coal Tar: Thick liquid used in manufacturing multiple substances.
- Coal Gas: A fuel derived from coal distillation, used in various industries.
- Ammonia Liquor: A by-product used in fertilizer production.
Oil Extraction and Reservoirs
- Oil extraction involves obtaining usable oil from the Earth’s surface.
- Oil reservoirs have specific characteristics that influence extraction methods.
Oil Production Process
- Primary Production: Natural oil flow that may last days to years.
- Secondary Recovery: Enhanced extraction methods to obtain more oil.
Crude Oil
- An unrefined petroleum product consisting of hydrocarbons.
Oil Refining
- Fractional distillation separates crude oil into components based on boiling points.
Uses of Distillation Products
- Various products obtained from crude oil are essential in everyday applications.
Petroleum Shortage & Conservation
- Addressing petroleum shortages requires effective conservation strategies.
Natural Gas
- A colorless, odourless fossil fuel, moved through pipes for distribution.
- Compressed Natural Gas (CNG): Stored under high pressure, offering several advantages.
Occurrences of Natural Gas in India
- Found in Tripura, Rajasthan, Maharashtra, Tamil Nadu, and Andhra Pradesh, highlighting regional resources.
