Abstract

THE ANALYSIS OF THE PRODUCTION VOLUME AND COKE QUALITY OF UKRAINIAN COKECHEMICAL ENTERPRISES IN 2020 © S.A.

2020年乌克兰焦化企业产量及焦炭质量分析

2020年乌克兰焦化企业产量和焦炭质量分析©S.A. Kravchenko，技术科学博士(国有企业“焦炉和副产品企业设计研究所”(SE“GIPROKOKS”)，60 Sumska街，哈尔科夫，61002，乌克兰)，A.G. Starovoit，技术科学博士(乌克兰科学和工业协会“UKRKOKS”)，1 Geroev Maidana广场。(乌克兰，第聂伯罗，49000)，O.V. Turkina, S.V. Chaplianko，技术科学博士(SE“GIPROKOKS”)。对乌克兰8家焦化企业以及位于乌克兰控制领土的工业在2020年的产量和焦炭质量进行了分析。结果表明，焦化工业所需的进口煤炭占73.5%，国内煤炭在原料基础中的份额比2019年增长3.1%。这些企业的煤料质量比世界主要焦炭生产商的煤料质量低12%(相对百分比)，与2019年相比低1.3%。6%水分毛焦产量9707万吨，比2019年减少3.2%。由于主要产品产量的减少和炉料组成的变化，副产物的产量发生了变化(焦炉煤气的产量减少了2.0%，煤焦油减少了0.6%，苯减少了11.2%，硫酸减少了16.4%，硫酸铵的产量增加了0.6%，工业气体硫增加了0.7%)。乌克兰产焦炭的整体质量完全符合相关技术规范和世界最佳同类产品的要求。一项确定国内生产商焦炭在向乌克兰冶金企业供应的焦炭总量中所占份额的研究发现，在2017-2021年期间，制造(包括出口)和供应(包括进口)焦炭之间的差异为14.7 - 16.7%，进口份额为2.4 - 9.7%。由于俄罗斯联邦于2022年2月24日爆发对乌克兰的武装侵略，有必要对该国所有焦化设施进行调查。这种调查的相关性和实际意义还在于需要评估乌克兰因武装侵略所遭受的损害。考虑到PJSC“MK”AZOVSTAL和PJSC“AKHZ”由于炮击而被摧毁，国内企业制造产品的能力问题变得非常相关。关键词:分析，焦炭生产，煤料，焦炭质量。通讯作者S.V.
