煤焦油综合利用技术评估

Technical evaluation of coal tar comprehensive utilization

针对煤炭炼焦、兰炭生产、煤制气以及褐煤热解等煤化工生产过程中伴生的大量高温、中低温及低温煤焦油综合利用技术种类繁多且缺乏有效的评估体系,采用现场调研和专家咨询方法,确定经济成本、技术特性、资源能源消耗、资源综合利用、污染物产排特征五个定性、定量评估指标,并通过专家评分、判断矩阵法计算各单项指标的权重分别为0.375 0、0.214 7、0.121 5、0.074 1、0.214 7.构建的煤焦油综合利用技术评估指标体系可作为最佳可行技术筛选的客观依据,同时可为企业以及相关管理部门从"经济-技术-环境"这一角度进行技术选择提供基础支撑.

The massive coal tar with high temperature, medium temperature and low temperature are coming trom me production process of coke making, semi-coking producing, coal gasification and lignite pyrolysis. According to the wide range of comprehensive utilization technology and the lack of effective evaluation system, combining with site investigation and expert consultation, five quantitative and qualitative evaluation indexes including economic cost, technical characteristics, resources and energy consumption, comprehensive utilization of resources and pollutants production characteristics are selected. Through expert grade and judgment matrix methods, the calculation result of each index weight is 0.375 0, 0.214 7, 0.121 5, 0.074 1 and 0.214 7 respectively. The construction of technical evaluation system can provide important reference for screening the best available techniques and afford basic support for enterprise and related management departments to determine the optimum comprehensive utilization techniques from economic-technique-environment perspective.
