煤基产业的资源循环利用与低碳流程再造

Resource recycling and low-carbon process reengineering in coal-based industry

面向碳中和与碳达峰的战略目标,立足于富煤工业区偏重煤的能源经济结构,讨论了煤基产业在资源循环及低碳生态环境中面临的挑战。首先,基于工业生态与循环经济的路线,从去产能与国土空间规划减排,到过程工业再造减排,再到零碳技术园区的建设,对煤电、化工和过程工业等煤基产业的发展提出了一些建议。其次,介绍了煤基废弃资源循环利用的具体措施,包括焦化废水的深度处理与回用、固体废弃物的材料化/能源化利用,以及低品位资源综合利用的途径等。最后,总结了二氧化碳减排与资源化利用的多种方式,以二氧化碳的矿化固定与绿色转化为主,在实现煤基产业的绿色转型发展的同时,实现超低碳排放。

Facing the strategic goals of carbon neutrality and carbon peaking,based on the energy economic structure of coal-rich industrial areas,challenges faced by resource recycling in coal-based industries and lowcarbon environmental ecology are discussed.First of all,based on the route of industrial ecology and circular economy,some suggestions are put forward for the development of coal-based industries such as chemical engineering and coal power.Specifically,it includes the reduction of overcapacity and the reduction of land and space planning,the reduction of emissions from process industry reengineering,and the construction of zero-carbon technology parks.Then,the specific measures for the recycling of coal-based waste resources are introduced,including the advanced treatment and reuse of coking wastewater,the materialization/energy utilization of solid waste,and the comprehensive utilization of low-grade resources.Finally,various ways of carbon dioxide emission reduction and resource utilization are summarized,focusing on the mineralization and fixation of carbon dioxide and green transformation,while realizing the green transformation and development of the coal-based industry,ultralow-carbon emissions might be controlled.
