Abstract
An apparatus for vaporizing volatile liquids comprises a packed column, a gas inlet port (for introducing a hot entrainer gas), a feed tube (for introducing a volatile liquid), a feed distributor comprising a base plate equipped with orifices (through which the liquid flows downward into the packed column) and risers (through which the formed gaseous mixture of entrainer gas and vaporized liquid flows upward), and a gas outlet port. This apparatus can be used to vaporize volatile liquids, preferably volatile tin compounds, optionally in admixture with volatile silicon compounds, wherein steam is used as the entrainer gas.
Claims20
An apparatus for vaporizing volatile liquid materials comprising:
- (a) a packed column containing a bed of substantially inert, solid particles;
- (b) a gas inlet port being located below said bed of solid particles;
- (c) a liquid feed tube having a plurality of downwardly-directed holes, said tube being located above said bed of solid particles;
- (d) a feed distributor comprising a plate, a plurality of orifices extending through said plate and a plurality of open riser tubes mounted on said plate, said plate being located between the top of said packed column and said liquid feed tube;
- and (e) a gas outlet port being located above said feed tube.
A process for vaporizing a volatile liquid substance which comprises:
- (1) providing an apparatus comprising (a) a packed column containing a bed of substantially inert, solid particles;
- (b) a gas inlet port being located below said bed of inert solid particles;
- (c) a liquid feed tube having a plurality of downwardly-directed holes, said tube being located above said bed of solid particles;
- (d) a feed distributor comprising a plate, a plurality of orifices extending through said plate and a plurality of open riser tubes mounted on said plate, said plate being located between the top of said packed column and said liquid feed tube;
- and (e) a gas outlet port being located above said feed tube:
- (2) introducing a hot entrainer gas through said gas inlet port;
- (3) establishing an upward flow of said hot entrainer gas in said packed column;
- (4) introducing a volatile liquid through said liquid feed tube and forcing said volatile liquid to flow through said multiple downward-directed holes onto said distributor plate;
- (5) forcing said volatile liquid to flow through said orifices into said packed column;
- (6) vaporizing said volatile liquid and forming a gaseous mixture of said hot entrainer gas and of vaporized liquid in said packed column;
- and
- (7) forcing said gaseous mixture to flow upward through said plurality of open riser tubes and to exit through said gas outlet port.
