Abstract

1322902 Condensers wherein vapour is condensed by direct contact with cooling medium IMPERIAL CHEMICAL INDUSTRIES Ltd 4 Nov 1970 [5 Dec 1969] 59511/69 Heading BIB [Also in Division C2] The vapour of 1,2-dichloroethane, mixed with water-vapour and non-condensable gases, is condensed without the formation of ice by passing the vapour-mixture through inlet 2 into ring-packed tower 1 which is supplied through pipe 3 with a countercurrent stream of a liquid medium, such as calcium chloride brine, at sub-normal temperature sufficient to condense both the dichloroethane vapour and the watervapour. A mixture of brine and condensed dichloroethane is withdrawn from the base of the tower through pipe 4 into separator 5. Condensed dichloroethane is withdrawn from the system through pipe 6. A small amount of the separated brine is rejected through pipe 12, and the remainder is pumped back to the top of the tower through cooler 11. Non- ccndensable gases are discharged from the tower through pipe 13. The temperature of the brine is suitably in the range 0‹C to -40‹C. and of concentration 25% to 32% Ca Cl 2 . Instead of brine, ethylene glycol may be used as cooling-liquid.
