中国合成氨行业清洁生产潜力分析

Potential assessment of cleaner production in China's ammonia industry

随着资源环境矛盾的日益突出，在能源资源消耗严重、污染物排放高的中国合成氨行业开展清洁生产具有重要意义。该文在分析合成氨行业清洁生产现状的基础上，建立基于产能调整和技术改造的清洁生产潜力核算方法，并通过情景分析对2020年的清洁生产潜力进行了核算。结果表明：注重源头削减的清洁生产模式可促进行业清洁生产目标的实现；到2020年，5种主要污染物产生总量相对于2010年都有不同程度的削减，其中氨氮的削减幅度最大（为37％～71％），SO2和固废的削减幅度较小（分别为24％～33％、11％～18％）；不同的污染物和能耗的削减，可主要通过产能调整或相应的技术改造加以实现。

While the issue of resource conservation and environmental protection is highly concerned, it is essential to promote cleaner production in China＇s ammonia industry, which has large energy consumption and creates considerable pollution. Based on the review of the cleaner production status of ammonia industry, a method was developed to assess cleaner production potential by production capacity adjustment and technology promotion. Scenarios were designed to predict cleaner production potential in 2020. The results show that cleaner production mode is favorable to the achievement of cleaner production. By 2020, the total generation quantities of 5 types of pollutant will decrease differently compared with 2010. NH3 -- N is expected to decrease by 37%--71%, which is the most significant, with SOz and solid waste only decreasing by 24%--33% and 11%--18 %, respectively. The reduction of pollution and energy consumption can be realized by production capacity adjustment and promotion of related technologies.
