Abstract

本发明涉及轻油裂解废渣综合治理和利用技术领域,特别是涉及一种轻油裂解废渣制备氰化锌联产混合硫酸盐的方法,其主要技术方案为:用40~60℃的5~10%硫酸锌溶液洗涤轻油裂解废渣,经抽滤后放入减压蒸馏器经40~60℃的低温减压蒸馏、冷却得到氰化锌晶体,剩余的液体经再次蒸馏得到混合的硫酸盐;本发明不但制备工艺和设备简单易行,而且成本低廉,消除对环境的影响,同时创造出有一定经济价值的产品。
The invention relates to the technical field of comprehensive treatment and utilization of light oil cracking waste residue, in particular to a method for preparing zinc cyanide co-production mixed sulfate by the light oil cracking waste residue, and the main technical scheme comprises the following steps: washing the light oil cracking waste residue by zinc sulfate solution with the temperature of 40-60DEG C and the concentration of 5-10 percent, after air pump filtration, putting the waste residue into a reduced pressure distiller, performing low-temperature reduced pressure distillation and cooling to obtain zinc cyanide crystal, and distilling the residual liquid again to obtain the mixed sulfate. The method has not only simple and practicable preparation process and equipment but also low cost, and can remove the effect on the environment and creat products having certain economic value.
