Coke Ovens-Sinter-BF-BOF Route. The most common steel making technology is the Bf-Bof Route. Coke is used in Blast Furnace (BF) both as a reductant and as a source of thermal energy. It involves reduction of ore to liquid metal in the blast furnace and and refining in convertor to form steel. The various stages of the steel plant is described ...
How a Coke Plant Works. Coal is the main ingredient used to make coke. Iron is produced by inputting coal into a blast furnace. However, coal cannot be put directly into a blast furnace because of all the harmful by-products that come from that. So, there is an intermediate process that occurs. Coal is converted into coke first.
Coking is the primary process used to upgrade petroleum residues. This process produces a solid coke which has a high carbon content. There are two types of coking processes, fluid cokers and delayed cokers. The delayed coking process is much more prevalent. In delayed coking, the process is designed so that the coke forms in a drum.
Global steel production is dependent on coal. 70% of the steel produced today uses coal. Metallurgical coal – or coking coal – is a vital ingredient in the steel making process. World crude steel production was 1.4 billion tonnes in 2010. Around 721 million tonnes of coking …

12.2.1 Process Description1-9, 16, 194 Most coke is produced in the U. S. using the "byproduct" process, and three plants used a "nonrecovery" process in 2007. The following discussion addresses the more common byproduct process first and then describes the nonrecovery process along with the major differences between the two that
are the feed slates for delayed coking . Once cracked, however, these residues are converted into valuable products . • Light gas to LPG and refinery fuel gas • Naphtha to gasoline pool • Gas oil to the refinery distillate blend pool for heating oil • Coke, largely used as fuel for power plants and steel mills and as anodes for the aluminum
the process of subsurface coal extraction and thermal coal processing. Purpose Coal is used for its potential heat energy when burned and since the 1880s has been widely used to generate electricity in power plants. To to generate electricity coal is first burned inside a power plant and the heat generated by the coal is then used to heat water.
In addition to the aqueous material obtained with distillation during the coking process, quenching of hot coke generates effluent with high suspended matter, while washing the produced gas results in a toxic liquid with high concentration of nitrogenous compounds and cyclic organic molecules (Ghose 2002; Kwiecińska et al. 2017).Some of these compounds are volatile under the conditions ...

Coking/metallurgical coal is one of the essential raw materials for steel industries. The metallurgical coal in India contains high ash content (mineral matters), is rich in inertinite, and requires optimization before its proper utilization. Distribution of mineral matter in coking coal plays a significant role in achieving the desired product for blast furnace and coke-making operations. The ...
Coal utilization - Coal utilization - Carbonization (coke making): Coke is the solid carbonaceous residue that remains after certain types of coal are heated to a high temperature out of contact with air. The process of heating coal in this manner is referred to as carbonization or coke making. High-temperature carbonization, with which this section is concerned, is practiced to produce a coke ...

Coal crushing The different grain size distribution of the raw coal is cause by the different structural strength, methods of mining and processing. This effects the requirements for the coal handling system of the coke oven plant. The main equipment for this process is the crusher station. Normally it is equipped with hammer mills.
Coking plant. Coal is needed when producing liquid hot metal in the blast furnace. However, we cannot utilise coal directly in the blast furnace as it contains a lot of harmful and unnecessary by-products. Coal is furthermore not strong enough to carry the blast furnace load. This is why we start by converting our coal into metallurgical coke.
Fig 1 Typical process flow and emission stream Coking coals and factors affecting coke quality Coking coal is an important raw material in the production of coke in the byproduct coke ovens since it decides the coke properties.The required coke properties are uniform size, good strength (CRI, CSR and micum values), porosity with minimum volatile matter and minimum ash.
