Hydrocyanic acid (HCN) is an important raw material for chemical production. The synthesis process of HCN mainly includes the direct method and the acrylonitrile by-product method. Due to the problem with low conversion, high impurity content, complex production operation and controlling difficulty that traditional technology has in the production of hydrocyanic acid and its derivatives .there are some problems. Based on the Andersen process, DODGEN developed a new technology of hydrogen cyanide synthesis process in order to optimize the traditional one.
