介绍硫基复合肥装置技改后,既可生产硫基复合肥又可生产粒状MAP和DAP的工艺流程及设备选型;技改后的2套硫基复合肥装置,每年在淡季时生产粒状MAP和DAP 6万t,可创经济效益1 000万元。同时介绍全部用国产白钾代替进口红钾生产硫基复合肥的技术,每年生产50万t硫基复合肥,可节约原料成本8 000万元。
Describe the technological transformation of sulfur-based compound fertilizer plant, both the production of sulfur-based compound fertilizer and granular MAP and DAP production process and equipment selection; technical transformation of the two sets of sulfur-based compound fertilizer plant, the annual production in the off-season granular MAP and DAP 60000 t, can create economic benefits 10 million yuan. At the same time, it introduces all the technology of producing sulfur-based compound fertilizer with domestic white potassium instead of imported potassium, and annually produces 500,000 tons of sulfur-based compound fertilizer, which can save raw material cost of 80 million yuan.
