MASS EXCHANGE TOWER WITH CROSS CURRENT OF SYSTEM LIQUID AND GASEOUS PHASES Russian patent published in 2016 - IPC B01D3/14 B01J19/32 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to cross current packed heat-mass exchange towers. Mass exchange tower with cross current of liquid and gas phases includes housing, raw material supply unions, distillate and residue output, auxiliary flows inlet and outlet, cross current nozzle sections separated by height with horizontal partitions, having along gas phase in normal housing cross section gas passage opening from nozzle inlet side and continuous section from nozzle outlet side, which alternate on adjacent by height horizontal partitions with arranged between nozzle adjacent sections and above nozzle upper section liquid distributors, which consist of three successively coupled parts: horizontal web, set of steps and blind pocket.

EFFECT: invention provides high efficiency of mass exchange tower operation, in which sharp change of flow rates of liquid phase is possible, expansion of device stable operation range, and possibility to use of contact devices with different number of flows in single device.
