CYCLONE ADSORBER FOR NATURAL GAS PURIFICATION Russian patent published in 2021 - IPC B04C5/22 B01D45/12 B01D45/18 

FIELD: gas purification.

SUBSTANCE: invention relates to a gas purification technique and can be used to purify natural gases from harmful impurities, namely, gaseous sulfur compounds (hydrogen sulfide, etc.). A cyclone adsorber for natural gas purification contains a cylindrical body, inside which a vertical central pipe is placed coaxially, a horizontal annular baffle with a central hole diameter larger than the central pipe diameter is located from top to bottom, the cavity between which and the housing cover forms an annular wash water collector, the central hole of which is connected with the upper edge of the perforated pipe of the irrigation jacket, forming between itself and the central pipe an annular slot with a gap equal to Δ₁, plugged from the bottom by an annular strip, adjacent to the lower side of the annular partition, perforated from the side, from the inside and from the bottom, an annular cylindrical basket with a gap between it and the body, closed from above by an annular partition, open from below and equal to Δ₂, wherein an annular cylindrical basket is filled with pumice granules made of metallurgical slags with a basicity modulus of M>1 and a granule diameter of 5 to 10 mm, an inlet pipe is tangentially passed through the top of the basket, and an annular rinse water collector and a conical bottom of the body are equipped with a rinse water supply connection and drain fitting.

EFFECT: increasing the efficiency of the cyclone adsorber for natural gas purification.
