Abstract
The washing and distillation tower (WDT) is a general equipment which can combine wet washing with distillation. In order to solve the problems of incomplete removal of solid particles, low efficiency of gas-liquid separation, small flexibility and easy blockage of internals of conventional WDT, a combined washing and distillation technology (CWDT) was developed by coupling inertial dust removal with flow-guided sieve tray, dual-flow tray and micro-bubble mass transfer technology (MBT). Experimental research, by laying a MBT mesh up the tray, was carried out based on the new MBT to examine the change of the mean bubble diameter, pressure drop and total gas hold-up under different operating conditions. The experimental results show that the mean bubble diameter can be reduced from 20 mm–57 mm to 1 mm–3.5 mm, greatly increases the washing effect and gas-liquid mass transfer efficiency. The technology has been successfully applied to the synthesis of organosilicon monomer and the heat recovery process of crude gas, and achieved good results, which proves the feasibility and advancement of the technology.
