Nayara Energy- Oil Refinery in India & leading Petroleum Company

Petcoke

Petcoke is cheaper and has a better availability than coal, increasingly making it the fuel choice.

Petcoke Benefits

COST

Cheaper than many fuels on a calorific basis,
capture of entire calorific value of
fuel leading to higher efficiency

AVAILABILITY

Increasing supply

CALORIFIC VALUE

Reliable supplies from various refineries,
high net calorific value

ASH

Lower ash with no disposal problems,
lower abrasion

HANDLING

Lower quantity of fuel to be handled,
lower area required for storage,
non hygroscopic: doesn't absorb moisture,
lower handling and transportation losses

Applications

Anode grade petcoke - raw or green petcoke with low metal and sulphur content can be calcined to be used for making anodes

As pulverised fuel or to circulate fluidized bed for heat and steam generation in power boilers across various industries

As fuel in kilns for clinker manufacturing in the cement industry

Fuel grade petcoke - raw or green petcoke with higher metal and sulphur content is used only as fuel

By gasification into syngas, it is used as a feedstock in refining chemicals and fertilisers

Petcoke vs. Coal

PARAMETER	SIGNIFICANCE	PETCOKE	COAL
Carbon	Calorific value is higher with higher carbon content	Very high	Low
Fixed Carbon	Higher fixed carbon indicates longer time to burn completely	High	Low
Volatile Matter	Higher volatile matter indicates easier and faster ignition	Low	High
Ash	Higher ash indicates lower calorific value, higher heat loss and disposal issues	Very low	High
Sulphur	Higher sulphur causes corrosion and pollution	High	Low
HGI	Higher HGI indicates easier grindability	Lower	Higher

Grading Parameters

PROPERTIES	CHARACTERISTICS	APPLICATION
Sulphur	Corrosion Pollution	Corrosion by sulphuric acid reduced by maintaining exhaust gas temperature above its dew point Use of lime to absorb sulphur
Metals	Corrosion	Additives to prevent cold corrosion by vanadium
Combustion	Residence time Ignition	Increasing residence time to ensure complete combustion Secondary fuel only during startup
Pulverization	Grindability	Suitable grinding equipment
