MULTITUBULAR REACTOR WITH DESCENDING FILM FOR CONTINUOUS SULFURIZATION AND/OR SULFATION OF LIQUID ORGANIC SUBSTANCE Russian patent published in 2001 - IPC

FIELD: continuous production of sulfurized or sulfated products using gaseous diluted sulfur trioxide (SO_3(dil)) for obtaining surfactants in cosmetic and detergent industries. SUBSTANCE: each separate nozzle set includes female part 19 and other half 45 on male part 10. Male part 10 forms circular slot 21 together with female part 19 at constant and limited length 47 and width fixed by hole, thus providing for individual pressure differential in slot and consequently individual flow rate of organic agent. EFFECT: enhanced smoothness of distribution of organic agent without any calibration. 8 cl, 3 dwg
