Pet-coke Current Affairs

India’s first Coal-gasification fertilizer plant to come up in Talcher, Odisha

Prime Minister Narendra Modi launched commencement of work for India’s first Coal-gasification based fertilizer plant with pet coke blending will come up in Talcher, Odisha. The coal gasification based fertilizer plant is being developed by Talcher Fertilizers Limited (TFL).

TFL is joint venture company of GAIL (India) Limited (GAIL-29.67% stake), Coal India Limited (CIL-29.67% stake), Rashtriya Chemicals & Fertilizers Limited (RCFL-29.67% stake) and Fertilizer Corporation of India Limited (FCIL-10.99% stake).

Key Facts

The plant will be built at an estimated investment of Rs. 13,000 crore and is targeted to be commissioned by 2022. On completion, this plant will have capacity of producing 1.27 Million Metric Tonnes Per Annum (MMTPA) of Neem coated prilled urea using coal and petcoke as feedstock. Neem coated urea reduces leaching of nitrogen into soil and checks diversion of urea from agriculture uses.

For this plant, TFL has been allotted captive coal mine in Talcher region to ensure steady supply of the feedstock for maintaining continuous operations of the plant. It will produce 2.38 million metric standard cubic meter per day (MMSCMD) natural gas equivalent syngas from coal, leading to reduction in import bill of liquefied natural gas (LNG) by more than Rs 1,620 crore per annum.

Significance of Coal-gasification based fertilizer plant

It will use gas produced from coal, thus reducing dependence on urea and gas imports. It will promote alternative use of domestic coal in environment friendly manner, thereby supporting India’s commitments under CoP 21 Paris Agreement 2016. Pollutants like Carbon Dioxide (CO2) produced by this plant will be recycled for production of Urea and other by – products. Further, ash produced by it will be converted to inert slag which is non–hazardous.

Government bans pet coke import for fuel use

Directorate General of Foreign Trade (DGFT) under Ministry of Commerce and Industry has banned import of petcoke for use as fuel. But it has allowed its import of only for use as feedstock in some select industries such as cement, lime kiln, calcium carbide and gasification industries. These industries were earlier affected by petcoke-related policy flip-flops, which began after Supreme Court judgment (October 2017) banning use its in and around New Delhi to curb pollution.

Key Facts

India is the world’s biggest consumer of petcoke. It gets over half its annual petcoke imports of around 27 million tonnes from United States. Local producers include Indian Oil Corp, Reliance Industries and Bharat Petroleum Corp.  It is dark solid carbon material. Cement companies in India account for about three-fourths of country’s petcoke use. Usage of pet coke in energy-hungry India recently had come under scrutiny due to rising pollution levels in major cities.

Petcoke (Petroleum coke)

It is one of the many industrial byproducts produced during oil refining. It is categorized as bottom of the barrel fuel as it is residual waste material which is obtained after refining coal to extract lighter fuels like petrol. It is used as a source of energy and carbon for various industrial applications. It is abundantly used in India in several manufacturing industries such as cement, steel and textile as it is significantly cheaper that coal, has high calorific value and is easier to transport and store. There are two kinds of pet coke produced viz. Fuel grade pet coke (80%) and calcined pet coke (20%) during oil refining.

Environment and Health Hazards of Pet Coke

Petcoke is much more potent pollutant than coal and causes greater harm to the environment and health. It contains whopping 74,000 PPM of sulphur content which is released into atmosphere as emissions which is much higher than vehicular emissions. It is also source of fine dust, which can get through filtering process of human airway and lodge in lungs which can cause serious health problems. Apart from sulphur, petcoke also releases cocktail of other toxic gases after burning such as nitrous oxide, mercury, arsenic, chromium, nickel, hydrogen chloride and greenhouse gases (GHG) which contribute to global warming.
