绿色工厂理念在硫酸清洁生产中的应用

Application of green factory concept in clean production of sulphuric acid

介绍了云南三环中化化肥有限公司将绿色工厂理念应用于硫酸清洁生产的实践情况。通过对硫磺制酸生产进行源头管控和过程监控、回收各种热量用于副产蒸汽和代替燃煤供热、优化生产过程操作、利用硫磺渣生产含硫低养分肥料、利用液体硫磺的高热值及生产反应热实现高含硫磷肥低碳化生产等举措,硫磺制酸生产从源头到末端,并延伸到下游产品实现了绿色、清洁生产,不仅实现了经济效益的增长,还有助于改善硫酸的生产环境,实现企业的稳定发展。

The application of green factory concept in clean production of sulphuric acid in Yunnan Three Circles-Sinochem Fertilizer Co.,Ltd.is introduced.Through the measures of source control and process monitoring of sulphur-burning sulphuric acid production,recovering various heat for by-product steam and replacing coal-fired heating,optimizing production process operation,using sulphur slag to produce sulphur-containing low-nutrient fertilizer,using high calorific value of liquid sulphur and production reaction heat to realize low-carbon production of high sulphur-containing phosphate fertilizer,sulphur-burning sulphuric acid production realizes green and clean production from the source to the end and even to downstream products.This not only realizes the growth of economic benefits,but also helps to improve the production environment of sulphuric acid and realize the stable development of enterprises.
