“双碳”背景下热法黄磷生产技术研究现状及建议

Research status and suggestions of yellow hosphorus production technology by thermal processing under peak carbon dioxide emission and carbon neutrality

黄磷支撑着我国磷酸盐精细化和有机磷化工的发展,是磷化工行业重要的基础原材料。热法黄磷生产高能耗、高污染、高碳排放,因此创新产业可持续发展模式,突破资源、能源、环境的多重制约因素,开发绿色黄磷生产技术是我国黄磷企业今后发展的必经之路。结合“碳达峰、碳中和”的时代背景,本文阐述了黄磷生产技术发展及副产物资源化利用现状,目前黄磷生产存在磷矿资源贫化、副产物低值化利用普遍、能源转型难度高、企业整体能效水平低、产业链链接关键技术不足等问题,提出加快推广黄磷尾气烧结中低品位磷矿成球技术、加大开发资源化增值利用技术、探索黄磷还原新技术、加强企业合作、构建多产业耦合的磷资源产业循环经济五条建议,旨在助力实现黄磷行业节能降碳、绿色发展。

Yellow phosphorus is the important basic raw material of phosphorus chemical industry,which supports our phosphate refinement and the development of organic phosphorus chemical industry.Thermal yellow phosphorus production has the characteristics of high energy consumption,high pollution and high carbon emission.It is the only way for Chinese yellow phosphorus enterprises to innovate the sustainable development mode of industry,to break through the multiple constraints of resources,energy and environment,and to develop green yellow phosphorus production technology.Combined with the time background of“carbon peak and carbon neutrality”,this paper described the development of yellow phosphorus production technology and the status quo of by-product resource utilization.There were some problems in yellow phosphorus production,such as phosphate ore resource depletion,widespread utilization of low-value by-products,high difficulty in energy transformation,low overall energy efficiency level of enterprises and insufficient key technologies of industrial chain link.In order to realize energy saving and carbon reduction and green development of yellow phosphorus industry,this paper put forward five suggestions:to accelerate the promotion of pelletizing technology of low and medium grade phosphorus ore in tail gas sintering of yellow phosphorus,to increase the development of value-added utilization technology of resources,to explore new technology of yellow phosphorus reduction,to strengthen cooperation between enterprises,and to build a multi-industry coupled circular economy of phosphorus resource industry.
