随着国内外大规模磷铵装置的投产,粉状磷酸一铵(MAP)市场价格比粒状磷铵产品低,生产企业受市场、关税影响大。为了拓宽磷铵的市场,利用料浆法粉状磷酸一铵装置联产粒状磷酸一铵(GMAP)和粒状磷酸二铵(GDAP)产品,以满足市场需求,从而也盘活粉状MAP装置。以下介绍利用粉状磷酸一铵生产装置联产粒状磷酸一铵、粒状磷酸二铵的工艺。
With the large-scale production of ammonium phosphate plant at home and abroad, powdered MAP (MAP) market price is lower than granular ammonium phosphate products, manufacturers by the market, the tariff effect. In order to broaden the market of ammonium phosphate, powdered MAP plant was also activated by utilizing powdered ammonium monoammonium phosphate plant to produce granular monoammonium phosphate (GMAP) and granular diammonium phosphate (GDAP) products to meet the market demand. The following describes the use of powdered ammonium monoammonium phosphate production plant co-granular ammonium phosphate, granular DAP.
