PACKED GAS-DEHYDRATION ABSORBER (VERSIONS) Russian patent published in 2003 - IPC

FIELD: gas industry, particularly, devices for dehydration of gases, mainly, natural or associated gas. SUBSTANCE: packed gas-dehydration absorber has inlet separation section, mass-transfer absorption section filled with packing and outlet filtering section. It is made in the form of two located one above the other fully dismountable plates with ring sieve packings. Separation-gas distributing section is installed above mass-transfer absorption section. Located between inlet separation section and mass-transfer absorption section is semiblind plate for collection and withdrawal of used absorbent communicated with mass-transfer absorption section and outlet filtering section. The second version of claimed invention is distinguished by the fact that inlet separation section is made in the form of plate installed from the side of gas inlet. Plate is provided with centrifugal separating members and located above it in the form of layer of plate-sieve packing. EFFECT: higher degree of gas dehydration and operating reliability of absorber due to sharp reduction of absorbent carrying-away with dehydrated gas; reduced probability of getting of mechanical impurities together with dehydrated gas into mass-transfer absorption section. 3 cl, 1 dwg
