The technological value of coking coal may usefully be discussed in terms of the coking potential. Attention focuses on the coking potential of clinkering coal-alone, in blends from enrichment plants, or in coking batch. Calculation of the batch composition on the basis of predictors of technological value is proposed. © 2014 Allerton Press, Inc.

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.

A review of research on Ulug Khem coal between 1951 and 2013 shows that its properties are largely determined by the plant material from which it is formed. This results in different types of vitrinite in Ulug Khem coal, with differences in clinkering properties, vitrinite reflectance, and yield of volatiles. Detailed petrographic analysis of coal from the Ulug bed in the Mezhegei deposit shows numerous associations of collinite with telinite and of telinite with bitumenite and also numerous associations of vitrinite with minerals. Thanks to the different properties of different types of vitrinite in Ulug Khem coal, the different associations of vitrinite with minerals, and the high ash basicity, coke produced from batch containing Ulug Khem coal will be characterized by low CSR and high CRI. That finding will be discussed in part 2. © 2016, 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.

This review covers research at AO Vostochnyi Nauchno–Issledovatel’skii Uglekhimicheskii Institut (VUKhIN) over the past 50 years on the extraction of tar and naphthalene in the primary cooling of coke–oven gas and also on related topics such as the conditioning of coal tar and the cooling of ammonia liquor in surface heat exchangers. Some laboratory results that were not published during the author’s lifetime are presented here for the first time. © 2016, Allerton Press, Inc.

In the laboratory coking of production batches at OAO EVRAZ ZSMK, including those containing coal from the Elegest deposit, special attention is paid to batches with different quality of the clinkering, coking, and lean components, so as to determine the maximum possible content of Elegest coal in the batch if the coke produced is to be satisfactory quality for use in blast furnaces at OAO EVRAZ ZSMK with pulverized-coal injection. © 2016, Allerton Press, Inc.

A method is developed for determining the coking properties and technological value of coal from newly identified beds or new sections of existing mines. The coking properties are assessed on the basis of predictions of the strength and reactivity of coke obtained from batch containing coal from single beds and coal blends. The prediction of coke quality is based on the chemical and petrographic characteristics of the coal. © 2012 Allerton Press, Inc.
