Case-2 - with 8% Petcoke - SO3 in clinker was 0.55. Case-3 - with 25% Petcoke - SO3 in clinker was 0.9%. Case-4 - with 50% Petcoke - SO3 in clinker is 1.2% PROCESS IMPLICATIONS. The expected implications on process due to use of pet-coke are maintained as following: 1. The specific fuel consumption was likely to lower slightly. 2.
Since C2S is the least brittle of the four major clinker minerals, an increase in C2S over C3S will make the clinker harder to grind. (b) If you have a raw mix that is high in alkalis which are not balanced with sulphur, under oxidising conditions the sulphur from the petcoke will combine with the alkalis and produce a lot of alkali sulphates.

The investment is expected to allow the cement producer to expand its production capacity to 11Mt/yr from 6.75Mt/yr at present, according to the Economic Times newspaper. Wonder Cement, part of the Rajasthan-headquartered RK Group, announced in August 2018 that it was preparing to set up a 2Mt/yr clinker grinding unit in Dhule, Maharashtra.
Petcoke is the preferred fuel of choice for the Global cement industry after coal and lignite Petcoke is by far the preferred fuel of choice for European cement industry Cement industry is the largest consumer of petcoke in India (3.7 million tons per annum) Technology to use petcoke in cement plants is mature and easily available.

The aim of this replacement was to increase the kiln capacity to 9000t/day without impacting its NO x emissions whilst maintaining a good clinker quality despite a high sulphur content in the petcoke. The installation is now in production and an intervention is planned in the coming weeks to further optimise the operation.
For cement clinker and blast furnace slag ; higher compressive force is needed compared to limestone and coal. Very Fine material behaves like liquid and therefore de-aeration and pre-compaction is useful. For this purpose Two way grinding system has been developed by UBE for highly efficient grinding of Slag and Clinker.
In case study it was observed that : Case-1 - with import coal - SO3 in clinker was 0.4 Case-2 - with 8% Petcoke - SO3 in clinker was 0.55 Case-3 - with 25% Petcoke - SO3 in clinker was 0.9% Case-4 - with 50% Petcoke - SO3 in clinker is 1.2% 22.

Hima cement could resort to massive importation petroleum coke, a dirtier source of energy production for its cement production in Uganda. The factory in Kasese had from the onset been burning imported petroleum coke, better known as petcoke, a dark solid carbon material in clinker production. It had by mid this year turned 60 percent biomass ...
This work analyzes how gases emitted during the manufacture of clinker vary in a cement plant using two types of fuel: petroleum coke and unusable tires (UTs). This study is based on a case study using real time data on more than 40 process
The heart of clinker production is the rotary kiln where the pyroprocessing stage occurs. The rotary kiln is approximately 20 to 25 feet (ft) in diameter and from 150 ft to well over 300 ft long; the kiln is set at a slight incline and rotates one to three times per minute.
