该产品采用菏泽金江新材料有限公司开发的“第四代：催化脱色-结晶转化”工艺，以焦化厂HPF法脱硫废液中提取的高纯硫氰酸铵（96%-98%）为原料，通过“加碱转化”、“分离脱氨”、“脱色精制”、“蒸发浓缩”、“结晶精制”、“干燥包装”等步聚生产硫氰酸钠（98%-99%）。

The product is developed by Tai'an environmental protection science and 

technology limited company "fourth generation: crystalline 

transformation" process of catalytic decolorization, to extract the HPF 

desulfurization wastewater in coking plant of high pure ammonium 

thiocyanate (96%-98%) as raw material, through the "alkali 

transformation", "separation of ammonia removal", "decoloration 

refining", "evaporation concentration", "crystallization", "dry 

packaging" steps producing sodium thiocyanate (98%-99%).
