FIELD: industrial organic synthesis and gas treatment.
SUBSTANCE: invention is directed to treatment of emission gases in the cumene process-mediated phenol and acetone production. Treatment process comprises continuous-mode absorption of cumene from emission gases in a plant comprised of absorber, cooler, and pump. Cumene is removed from absorbent and reused in the phenol-acetone production process circuit. As absorbent, cumene production by-product, namely polyalkylbenzenes, is used at temperature below 10°C. Content of cumene in purified emission gases does not exceed 158 mg/m3.
EFFECT: simplified gas treatment procedure, eliminated complicated equipment and waste, and reduced cost.
