FIELD: process engineering.

SUBSTANCE: adsorber comprises vertical casing, support grate with adsorbent bed, metal separation screens and plies of ceramic balls arranged at support grate and above adsorbent ply, union at upper and lower case bottoms for processed gas inlet and outlet. Horizontal perforated circular web is arranged above adsorbent top ply to cover the case crosswise section, its central part being shaped to conical barrel diverging upward and having holes at its bottom. Perforated web between conical barrel and adsorber case has spaced apart holes of different diameters.
