To the reactor of the first stage (R01) with ethylenechlorohydrine is through the mixer (Z01) under continuous circulation of the reactive shaft added dry salt acid, later through the mixer (Z02) ethylene oxide. The reactive heat is removed by the heat exchanger (E01). Concurrently with the salt acid saturation washing the gases begins in the absorber over (R01) by undercooled raw ethylenechlorohydrine from the reactor of the second stage (R02) and to the (R02) is added ethylene oxide through the mixer (Z03). Degas from (R02) is conducted to the bottom part of the second absorber, countercurrently is sprinkled by the raw ethylenechlorohydrine, saturated salt acid, outgoing overflow from (R01). The raw ethylenechlorohydrine is continuously conducted to the reservoir (H01), from which it is lead to rectification. The pure water-free product, ethylenechlorohydrine is removed as a distillate from the head of rectifying column (C01). |
