| Abstract: | Based on the actual production of compound fertilizer plant in Shaanxi Huashan Chemical Industry Group Co., Ltd, the feasibility of co-production of granular DAP is analyzed through transportation of MAP acidic slurry from MAP unit to DAP unit, the co-production test, revamping scheme, operation points, operation effect and economic benefit are discussed. The total nutrients of DAP can be controlled in 60%- 60.5%, the increasing rate is 30%, the direct economic benefit is 30 million RMB Yuan in 2008. |
