Description

Phoenix Equipment Corporation has this used Adiponitrile (ADN) plant immediately available. ADN is produced by the electrohydrodimerisation (EHD) of acrylonitrile (AN). The dimerisation of AN is by direct electrolysis in the presence of a recirculated aqueous electrolyte solution. The basic reaction equation is given below: 2 CH2CHCN + 2 e- + 2 H+ --> NCCH2CH2CH2CH2CN The products are adiponitrile (ADN) and hexamethylenediamine (HMD), both of which are intermediates in the manufacture of Nylon salt.

Major Equipment
(13) EHD reactors and (2) separators for dimerisation of AN. Other major equipment includes: off-gas scrubbers, QAS extraction feed tank and column, AN stripper feed tank and column, ADN storage tanks and refiner column and flash column, AN stripper decanter and recovery column, recycle AN tank, PNP column, low boiler stripper column, solvent recovery column, evaporator, crystalliser, vacuum filter, buffer tank (mother liquior tank), lead removal system.
