1 Introduction. Petroleum coke ("petcoke") is regularly produced as a byproduct of crude oil refining, especially from heavy crudes commonly produced in Canada. While some forms of petcoke are useful for steel making or other speciality purposes, it is often stockpiled in large quantities as a waste product.

01 March 2016. Coal provides around 90% of the energy consumed by cement plants around the world, despite the environmental harm caused by its combustion. It takes 200 450kg of coal to produce 1t of cement. The cement industry consumes around 4% of global coal production, around 330Mt/yr. Given the rapidlyexpanding infrastructure projects ...

High grade petcoke which is low in sulphur and heavy metals can be used to make electrodes for the steel and aluminum industry. But the majority of petcoke manufactured globally, approximately 7580%, is of a much lower grade, containing higher levels of sulphur and heavy metals and is used solely as fuel. The majority of petcoke produced in ...

Abstract. Gasification is a mature technology to convert carbonaceous materials into valuable chemicals, fuel, or power. The technology of coal gasification is wellestablished; however, it has some inherent drawbacks like high ash content in Indian coal, slagging, and tar formation. Biomass gasification is a promising area, though sustainable ...

Fire and explosion protection of coal grinding systems. Where are we today? With 'everybody' in the cement industry focussing decarbonisation, but with coal grinding systems still being used in the foreseeable future, the topic dealt with here must not be shoved into the background. There is a serious need for change here too.

As petcoke has a higher energy content, petcoke emits between 30 and 80 percent more CO2 than coal per unit of weight. The difference between coal and coke in CO2 production per unit energy produced depends upon the moisture in the coal (increases the CO2 per unit energy — heat of combustion) and volatile hydrocarbon in coal and coke ...
