Topic in Syllabus: Science and Technology
- Odisha’s Talcher fertiliser plant awarded a contract for starting a coal gasification unit for the production of urea and Ammonia.
- It was part of the government’s initiative to revive closed fertiliser plants belonging to the Fertiliser Corporation of India Limited (FCIL) and the Hindustan Fertilisers Corporation Ltd (HFCL).
About Coal Gasification:
- Coal gasification is the process of converting coal into synthesis gas (also called syngas), which is a mixture of hydrogen (H2), carbon monoxide (CO) and carbon dioxide (CO2).
- The syngas have variety of applications such as in the production of electricity and making chemical products, such as fertilisers.
- The coal gasification process holds good potential in the future, with coal being the most abundantly available fossil fuel across the world, and that even low-grade coal can be used in the process.
Why Fertiliser plant at Odisha was shut down:
- Frequent power restrictions.
- Technology mismatch.
- Precarious steam balance.
Benefits of Coal Gasification:
- Reduce the import of LNG.
- India currently imports 50 to 70 lakh tonnes of urea every year, and that the revival of the units would help increase the availability of domestically produced fertilisers.
- Project would generate direct and indirect employment of around 4,500 people.
- Project’s environment-friendliness would help India in meeting its commitments under the CoP-21 Paris Agreement.
Which of the following statements are true?
a) Anthracite has a carbon content of 60-75%.
b) Acid rain is caused by burning coals with a high sulphur content.
c) Coal originated from the decay of micro-organisms in the sea.
