A process scheme of deammoniation of sugar production condensates comprises the distribution of ammonia condensate above the packed column tapped thereof from below and backward supply of desorbent. The deammoniation is carried out in two stages, at that at the first stage ammonia is desorbed with air in ejecting apparatus, at the output from which a two-phase stream in the cyclone collector is divided into air saturated with ammonia, which is removed, and partly desorbed condensates, which together with the circulating fluid get at the second stage in of deammoniation into the ejector for desorption of residual ammonia with low-temperature steam of the fourth evaporator shell and they are separated from the top of the packed column into which to complete desorption of ammonia air is supplied from the bottom. |
