The idea of this paper is to properly utilize Indian lowrank coking coal (semicoking coal) with the blending of highrank imported coals and to reduce the overall cost of coke making. The blending of the coals has been done in two phases. Effect of blending mass ratio on the swelling index and plasticity parameters has been studied. The effect of maceral content, vitrinite reflectance, and ...

Types of Coal. On the basis of carbon content, it can be classified into the following three types: Anthracite. This is the best quality of coal and contains 80 to 95 percent has very little volatile matter and a negligibly small proportion of moisture.; It is very hard, compact, jet black coal having semimetallic lustre.; It has the highest heating value and is the most prized ...
Trace elements, released in gaseous form in the coal coking process to coke oven gas, such as mercury, or released as chemical compounds, such as the other tested elements, pass into the tar/water condensate and then into the ammonia liquor and products obtained from tar. A small part of the crude coke oven gas escapes into the air as fugitive ...
The company is currently operating three opencast mines MineI, MineIA and MineII in Neyveli, Tamil Nadu, with a total capacity of million tonnes per annum (MTPA). It is linked to the NLCIL thermal power plant, which has a capacity of 3,390 MW with a 250ME independent power producer. MineII has a capacity of 15 MTPA and has ...
Published on : 26 Oct 2022, 1:03 am. New Delhi: As a diversification initiative, NLC India Limited (NLCIL) is setting up a LignitetoMethanol project at Neyveli with a capacity of 1,200 TPD ( MTPA) at a capital cost of about Rs 4,400 crore.

Metallurgical or coking coal is a primary ingredient in the steel making process. More than twothirds of global steel is produced in basic oxygen blast furnaces. China is the largest consumer of premium coking coal in the world. Coking coal, generally known as metallurgical coal, is a naturally occurring sedimentary rock.
Metallurgical coal, also known as met and coking coal, is a naturally occurring sedimentary rock found within the earth's crust. Met coal encompasses a wide range of quality grades including hard coking coal, semihard cokingcoal, semisoft coking coal and pulverised coal for injection (PCI). All are used to make steel.

Regulation of Sulfur Forms During CoalBlending Coking of High OrganicSulfur Coking Coals. It can be concluded from the above that most of the inorganic sulfur can be removed from coal by physical process, and the organic sulfur associated with coal matrix can also be partially removed by some chemical processes.
In response to the shortages of coking coal, the grindingflotation separation process of coking middlings was proposed. Researchers considered that moderate comminution can improve the liberation degree and surface hydrophobic of coking middlings, and optimize the particle size distribution, thus enhancing the floatability [3,4,5,6]. However ...
Act 1971 which provided for the taking over of the management of coking coal mines and coke oven plants pending nationalisation of such mines and plants. Sec. 3 (1) of the Act declared that on and from the appointed day, the management of all coking coal mines shall vest in the Central Government.
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.

Metallurgical coals fall broadly into two types (Figure 1). Coking coal is heated in the absence of oxygen in a coke oven to produce coke, which is then charged into blast furnaces as the key fuel and reactant. Coking coal can be further divided into hard coking coal (HCC), semihard coking coal (SHCC) and semisoft coking coal (SSCC).
