PRODUCER GAS

Producer gas is by-product of the iron and steel production industry. The steel production process involves three key stages  during which there is creation of producer gases: of the following related types: (i) coke gas, (ii) blast furnace gas and (iii) converter gas.

The producer gases can be  utilised for combined heat and power (CHP) generation using producer gas generators. The produced electricity can meet the company’s power need in its daily production or be exported to the power grid. However, these producer gases currently often flared without being utilised.

Coke gas is created during the coke production process. This producer gas is by-product of high-temperature anaerobic distillation of coking coal. Coke gas is suitable for combined heat and power generation (CHP).

Blast furnace gas is a by-product of blast furnaces where iron ore is reduced with coke into metallic (pig) iron. The gas is used as fuel for steel manufacturing, but it can  be also combined with natural gas or coke oven gas for CHP generation.

Converter gas is a by-product of the steel production process from pig iron. Converter gas collection system which will capture gas currently being vented to the atmosphere. The gas gas is suitable for combined heat and power generation (CHP).
