該產(chǎn)品采用菏澤金江新材料有限公司開發(fā)的“第四代：催化脫色-結(jié)晶轉(zhuǎn)化”工藝，以焦化廠HPF法脫硫廢液中提取的高純硫氰酸銨（96%-98%）為原料，通過“加堿轉(zhuǎn)化”、“分離脫氨”、“脫色精制”、“蒸發(fā)濃縮”、“結(jié)晶精制”、“干燥包裝”等步聚生產(chǎn)硫氰酸鈉（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%).
