FIELD: technological processes, filters.
SUBSTANCE: invention is related to chemical industry and may be used for reduction of hazardous gas emissions into atmosphere. Solution contained in tower 1008 of regeneration, is supplied to filtering installation 15. Filter 13 is intended for separation of hard particles contained in solution. Substance for rinsing (V13, 15) is intended for water rinsing of reverse flushing 14A of hard particles filtered with filter 13. Reverse flushing water 14B containing hard particles is supplied to evaporation plant 16A, and is heated with saturated vapour 1046A, thus preparing reverse flushing water 14C, which contains concentrated hard particles. Besides evaporator 16A is intended for evaporation of absorbing solution 1005, which is contained in water of reverse flushing 14B. Evaporated absorbing solution 1047 is returned to regeneration tower 1008.
EFFECT: improved efficiency of CO2 regeneration system with continuous removal of hard particles from absorbing solution.
