悬浮液熔融结晶 - 高效的提纯备选方法

化工行业的熔融结晶设备。

工艺介绍

装置 DB Acetonitrile 3

基于悬浮液的熔融结晶系统的典型配置如图所示。粗成品在刮光面结晶器中冷却。可以是交换器类型或容器类型的结晶器,具体取决于特定的应用。结晶器生产出较纯的晶体,并浓缩剩余液体母液中的不纯物质。随后,这些晶体与富含不纯物质的母液分离,形成较纯的产品液流和废液。废液中含经过浓缩的不纯物质,但这些不纯物质同时也可能是值得回收提取的宝贵产品,具体取决于特定的应用。
Each individual crystal is suspended in the mother liquor and is allowed to grow free flowing in the liquid. With billions of crystals per cubic meter the growth surface can reach 5,000 to 10,000 m² per m³ of volume. This massive growth surface allows near ideal growth rates that result in the characteristic pure crystals expected from the eutectic crystallization process.

Since all of the impurities are now in the mother liquor it is most important to remove all of this liquid from the outside of the crystals. The crystallizer suspension is pumped into a wash column where the pure crystals are separated and then washed to remove any remaining mother liquor. The efficient washing action provided in the wash column is unmatched by any other solid/liquid separation device. The pure product crystals are then melted and discharged from the system.

Suspension based crystallizers produce pure crystals. Wash columns can effectively remove all of the mother liquor and thereby produce ultra high purity product.

Industrial applications
Capacities ranging from 10 kg/h up to 50,000 kg/h product
