A method has been developed for determining the technological value of coal in coking, on the basis of the predicted coke strength and coke yield from batch that includes such coal. The prediction of coke strength rests on the chemical and petrographic characteristics of the coal. The value of the coal in batches may be calculated in terms of the product of the coke strength and yield and the coke characteristics for standard batch. © 2011 Allerton Press, Inc.

The prospects for biotechnology in wastewater processing at coke plants are considered, in conditions of nitrification and denitrification. Wastewater-processing systems employed at Russian and foreign coke plants are compared. The degree of purification is about the same in Russia and elsewhere. However, the treated water does not meet Russian standards for delivery to municipal treatment plants and reservoirs from which fish are taken to be cooked. The single-phase AO VUKhIN biotechnology permits the removal of 80–90% of the nitrate present without the addition of organic reagents, in contrast to classical nitrification and denitrification technology. © 2016, Allerton Press, Inc.

On the basis of the newest metrology concepts formed around the term “uncertainty” and introduced by RMG 29 and GOST P 54500.3 standards, it is the first time when metrological models used in GOST 10742, GOST 27379 and ISO 13909—all devoted to coal sampling, are studied from uniform positions. Ways for effective income quality control and claims management regarding modern mechanical samplers are considered. © 2016, Allerton Press, Inc.

The concept of technological value is analyzed. Some characteristics of technological value are refined. The coke group and lean additives are redefined in terms of the metamorphism and vitrinite content of the coal. The technological value is qualitatively assessed in terms of the ranks in those functional groups. A program is proposed for calculating the coal batch used in producing coal of specified strength. © 2015, Allerton Press, Inc.
