Overview of Energy-saving and Carbon Reduction Measures in the Phosphorus Chemical Industry
The phosphate chemical industry in China faces the three restrictive factors of gradually diminishing phosphate ore resources,energy consumption control,and environmental constraints.In recent years,with the increasing emphasis on the sustainable development of the phos-phate chemical industry by the state,a series of policies and plans,such as the Action Plan for Comprehensive Utilization of Phosphogypsum and the Implementation Guide for Energy-intensive Industry Key Field Energy Saving and Carbon Reduction Upgrading(2022 Edition),have been launched.Based on this,this paper provides a detailed introduction to the suggestions for promoting the green development of the phos-phate chemical industry,including the nitric acid phosphate fertilizer process,the modification of the dihydrate process,multi-effect evapora-tion,and the utilization of phosphogypsum,as mentioned in the policies and plans.
