MEMBRANE GAS-SEPARATING MODULE Russian patent published in 2016 - IPC B01D63/04 B01D69/08 

FIELD: gas industry.

SUBSTANCE: invention relates to devices for separation of gas mixtures by means of hollow fibre membranes. Membrane gas-separating module comprises a horizontal casing with end covers and membrane cartridges made of a bundle of hollow fibers and located mirror-like relative to the centre. Housing has symmetrical end sections of larger diameter, conjugated by conical transition sections with the central section of smaller diameter. Herewith the length of the end sections corresponds to the length limited by the end of the housing and the input zone of membrane cartridges, and the inner diameter of the central section is made with possibility of simultaneous free mounting/dismantling of the membrane cartridges and their tight fit in the place of seal washers presence. Feed gas inlet pipes are arranged on the housing end sections perpendicular to its longitudinal axis opposite the inlet zones of membrane cartridges, permeate outlet pipes are arranged on end sections of the housing near the end covers perpendicular to the housing longitudinal axis.

EFFECT: technical result is the reduction of weight and size of membrane module and the whole gas-separation device.
