PROCEDIMENTO PERFEZIONATO PER LA SOLFONAZIONE A FILM IN UN REATTORE MULTITUBOLARE A REATTORE MULTITUBOLARE ATTO A REALIZARE DETTO PROCEDIMENTO

摘要

The reactor 1 has vertical tubes 10 connected at the top to two common chambers 15 and 17 feeding an organic liquid and an SO3- containing gas respectively. At the bottom the tubes enter a common collecting chamber 40. The gas is fed into the tubes 10 at a pressure of 0.1 to 0.5 bar, which is substantially the same as the head loss over the length of the tubes 10. The liquid is fed into each tube 10 at an overpressure equivalent to 1 to 100 cm of liquid column with respect to the gas feeding pressure. The tubes 10 are externally cooled by water supplied at 20 and withdrawn at 21.
