Title: Condensing vapours from gases
IPC: B01D5/00
Filed: 1961-08-08
Abstract: 958,698. Condensing vapours from a stream of vapour-laden gas. K. W. WILLIAMS, and J. W. WILLIAMS. Nov. 6, 1962 [Aug. 8, 1961], No. 28575/61. Heading B1B Vapours are condensed from a stream of vapour-laden gas, e.g. moisture-laden air, by passing the gas through insulated chambers 10, 11 and 12, which are loosely packed with heatabsorbent material at a lower temperature than the inlet gas. The packing in the chambers is previously cooled by passing a cold gas through the chambers until the temperature of the outlet gas is substantially equal to the temperature of the inlet gas. The vapours condense on the packing, and the resultant condensate is collected at the outlet 14 of chamber 12. When the outlet condition of the vapour-laden gas is substantially equal to the inlet condition with respect to the temperature and the humidity, the flow of gas is stopped, and the packing recooled by passing a cold gas stream through it, as previously described. The chambers may be tunnels cut in a hillside. The packing used comprises blocks of stone or metal stacked upon each other in rows across the chambers so that there are gaps between adjacent blocks. The warm inlet gas from fan 17 may already be saturated with vapour, or may be saturated by placing trays 18 of water in inlet 16, or by spraying water into the inlet gas. In localities where there is a considerable difference between day and night temperatures, the cold night air can be used for cooling the blocks in readiness for the condensing stage on the following day.
