Our refinery’s state of the art Delayed Coker Unit (DCU) produces high sulphur Petroleum Coke (Pet Coke) which is the carbonaceous solid residue remaining after the distillation of petroleum materials. Pet coke has more than twice the calorific value of coal and is widely used as an alternative to coal in power plants, cement kilns and blast furnaces.
Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. Any coal using industry can be a potential consumer of Petcoke. Major industrial segments using Fuel grade Petcoke in India are :
BIS specification of petcoke as per IS:8502-1994 is given below:
| Particular | Value |
|---|---|
| Moisture (% mass, max) | 8-12 |
| Moisture (% mass, max) | 4.5-7.5 |
| Ash, % mass, max | 0.2-0.3 |
| Volatile Matter, %mass, max | 8-11 |
| Fixed Carbon, % mass, min | 87.93-91.01 |
| Gross Calorific Value, (GCV) Kcal/kg | 7,800-8000 |
Petroleum coke is the solid residue remaining after the distillation of petroleum materials. It is a carbonaceous solid derived from oil refinery Delayed Coker Unit.
High Carbon Content : It’s high carbon content makes it an excellent heat energy source.
High Calorific Value : Petcoke has high calorific value, ranging from 7000 to 8500 Kcal/kg, which makes it an economic fuel as compared to the alternate fuel coal.
Low Volatile Matter : Low volatile matter makes it a slow burning fuel so it requires high ignition temperature.
High Sulphur Content : It has high Sulphur content, which necessitates the deployment of SOx capture or removal system to reduce SO2 emissions. However, Petcoke is ideal for burning in lime kilns, where the sulphur combines with various salts of calcium to form sulphates, thus limiting the SO2 emission.
Low Ash Content : Petcoke has extremely low ash content, which eliminates the need to handle and dispose high quantity of ash associated with combustion of Indian coal having 15-35% ash.
High Hard Grove Index : Pet coke has low Hard Groove Index, which makes it relatively harder material to grind and pulverise.
Comparison Of Indian Coal, Imported Coal & Petcoke

Our Sulphur Recovery Unit (SRU) produces Sulphur in powder and lump form. Maximum usage of Sulphur is for production of Sulphuric Acid which is widely used as a raw material for producing phosphatic and nitrogenous fertilizers. In raw form Sulphur is also used in explosives, sugar industry, match sticks etc

Our special products portfolio includes Premium Grade Mineral Turpentine Oil (MTO) that meets the stringent norms set by major paint manufacturers and Food Grade Hexane that meet the requirements of sensitive industries such as Pharmaceuticals
Fly Ash is the residue left after combustion of Pet Coke in the refinery's captive power plant. Due to its cementitious properties, it is excellent for manufacture of cement and bricks. India is the second largest brick maker in the world after China. Usage of Fly Ash in making bricks, compared to traditional clay bricks manufacture, reduces pollution.
