FIELD: process engineering.
SUBSTANCE: invention relates to plant, reactor and continuous production of high-purity silicon tetrachloride or germanium tetrachloride by treating silicon tetrachloride or germanium tetrachloride contaminated by, at least, one hydrogen-containing compound with the help of cold plasma and differential distillation of treated phase. Treatment if carried out in plasma reactor 4 wherein lengthwise axes of dielectric 4.4, high-voltage electrode 4.3 and earthed metal heat exchanger 4.2 are directed parallel each other and, at the same time, with gravity vector.
EFFECT: higher efficiency of purification.
