At most coke plants, the existing technologies for the capture of coking byproducts are not the best available. Accordingly, the working areas of coke plants and the atmosphere are polluted with copious emissions. At the world’s leading coke plants, the byproduct-trapping shop is free of toxic emissions. Emissions are prevented by modern byproduct-capture systems and by measures such as sealing of...... hiện toàn bộ
Structure of Carbon Sorbents Produced from CoalAllerton Press - Tập 61 - Trang 463-468 - 2019
A. P. Nikitin, I. Yu. Zykov, A. P. Kozlov, Z. R. Ismagilov
Samples of coal and sorbents derived from coal are investigated by Raman spectroscopy. The results show that a three-dimensionally ordered carbon structure is obtained after carbonization of the initial coal. The sorbents are morphologically similar, regardless of the method of synthesis employed. The degree of graphitization is 12.9 ± 2%.
Composition of condensates and deposits in the transportation of metallurgical gasesAllerton Press - Tập 53 - Trang 462-467 - 2011

Analysis of the physicochemical properties, chemical compensation, and volume of condensates and deposits of metallurgical gases—coke-oven gas, blast-furnace gas, and converter gas—shows that metal-lurgical-gas condensates account for 10.8% of the total coke-plant wastewater. The metal content in the condensates does not exceed the limits on the metal content in wastewater sent for biochemical tre...... hiện toàn bộ

Preliminary data are gathered regarding the effectiveness of various reagents on the basicity of Kaa-Khem coal in laboratory flotation.
Deficiencies of State Standard GOST 1186-87Allerton Press - Tập 51 - Trang 125-131 - 2008
V. P. Sknar, A. P. Miroshnichenko
The Sapozhnikov-Bazilevich method, on which State Standard GOST 1186-87 is based [1], is preferable to other methods of investigating the clinkering properties of coal, in that it reproduces near-industrial coking conditions in miniature. This method permits study of the most important properties of coal and coal batches, formulation of their likely behavior in coking, and the prediction of coke q...... hiện toàn bộ
Coal flotation by ozonized spent motor oilAllerton Press - Tập 60 - Trang 154-157 - 2017
M. S. Klein, T. E. Vahonina, S. A. Semenova, Yu. F. Patrakov
The influence of ozonization on the composition and flotation properties of spent motor oil is investigated. Preliminary ozonization increases the proportion of low-boiling components in the spent oil, reduces its viscosity, and improves its flotation properties in the enrichment of coking coal.
