Petcoke

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 :

  • Cement Kilns
  • Thermal Power Plants
  • Brick Kilns
  • Lime Kilns
  • Cement Kilns
  • Thermal Power Plants
  • Brick Kilns
  • Lime Kilns

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

A comparison of specification of C grade Indian non-coking coal used by cement industry, coal imported from Indonesia and petcoke to be produced by HMEL is shown below

Parameter Average Values

Sulphur, (% mass, max) 0.8 1.00 7.5
Ash Content, (% mass, max) 32 4.5 NIL
Volatile Matter, (% mass, max) 27 41 10
Moisture Content (%mass, max) 4 16 10

Sulphur

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

Major Applications

Maximum usage of Sulphur is for production of Sulphuric Acid. Sulphuric acid is widely used as a raw material for producing phosphatic and nitrogenous fertilizers.

Fertilizer Application of Sulphuric Acid Non-Fertilizer applications of Sulphuric Acid Other applications of Sulphur in Raw Form
Single Super Phosphate (SSP) Diammonium Phosphate (DAP) Ammonium Sulfate (AS)
Batteries Detergents Paint Caustic Soda Titanium Dioxide Phosphoric Acid & Printing etc.
Sugar Industry Match Sticks Explosives Fire crackers Vulcanisation of Rubber Pharmaceuticals Dyes etc

The guidance values of assay and impurities as per BIS Standard IS:6655-1972, are as below

Characteristics Percentage by Mass
Assay (dry basis) 99
Colour Bright whitish yellow
Ash 0.25
Carbon 0.1 to 1.0

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

By-Products

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.
