| titleOfInvention | A kind of double-column in series rectification process for separating and purifying of hydrocyanic acid |
| abstract | The present invention relates to the double-column in series rectification process for separating and purifying of a kind of hydrocyanic acid, comprise the following steps: charging, the first rectifying column rectification, partial condensation, add polymerization inhibitor, Second distillation column rectification, partial condensation, backflow separates again.Use the purifying technique of the present invention, have the advantages that in hydrocyanic acid preparation process and do not cause rectifying column to block, reduce Operating Complexity；Improving rectification yield, obtain the hydrogen cyanide product of high-quality, product design reaches 99.98%, remains 0.001ppm in waste water；High concentration and the hydrocyanic acid aqueous solution of low concentration, all can obtain the hydrogen cyanide product of high-quality by present invention process. |
