Essar Petcoke

Essar also has its refinery in Jamnagar and Essar provides high quality Petcoke from its Jamnagar refinery. Petcoke (petroleum coke) is a bottom of the barrel product. It is a dark solid made of relatively pure carbon. It is produced at the delayed coker unit (DCU) in the refinery.

Essar Petcoke

According to Essar Specifications and regulations of Essar Petcoke is as follows

Parameter	Unit	Value	Significance
Fixed carbon	% (m/m)	85 – 91	High carbon indicates high calorific value.
Volatile matter	% (m/m)	< 12	Low VM indicates difficulty in igniting.
Gross calorific value	Kcal/Kg	7,800 – 8,000	Key from customer perspective. Significantly higher than coal.

Key parameters

Parameter	Unit	Value	Significance
Sulphur	% (m/m)	< 7.5	Lower is better as it is less polluting. Important from regulatory point of view.
Hardgrove Grindability Index (HGI)	–	38 – 52	Low value indicates difficulty in grinding.

Comparison of Petcoke Vs Domestic Coal

Petcoke
	High carbon content –> higher calorific value
	High fixed carbon content –> slower combustion
	Lower volatile matter production –> difficult to ignite
	Lower ash production –> less waste disposal
	High sulphur content –> high corrosion and pollution

Domestic Coal
	Very low carbon content –> very low calorific value
	Very low fixed carbon content –> faster combustion
	High volatile matter production–> easier to ignite
	Very high ash production–> heat loss, disposal problem
	Low sulphur content –> lower corrosion and pollution
