Abstract
The present invention is a low temperature ozone generator using a cryogenic cooling medium. The present invention also provides an efficient method of producing ozone using a cryogenic cooling medium. Finally, the invention is to a method for producing ozone efficiently using liquid nitrogen as the cooling medium.
Claims17
An ozone generator system comprising:
- ozone generation means having associated therewith means for introduction a reactant gas;
- means for contacting said ozone generation means with a cooling medium at not greater than about 0° C.;
- means for withdrawing a portion of said cooling medium after it has contacted said generation means;
- means for mixing said portion of said cooling medium with said reactant gas;
- and
- means associated with said ozone generation means for withdrawing the generated ozone.
3 more elements
A method for producing ozone, comprising:
- flowing reactant gas containing oxygen into an ozone generator to convert a portion of said reactant gas to ozone;
- contacting said ozone generator with a cooling medium at not greater than 0° C. to cool the ozone;
- removing said cooling medium after it contacts said ozone generator;
- converting at least a portion of said cooling medium to a gaseous coolant;
- mixing at least a portion of said gaseous coolant with said reactant gas;
- and
- withdrawing a product stream containing the ozone generated in said ozone generator.
4 more elements
An ozone generator comprising:
- a tubular ozone generator surrounded by a housing;
- a gas inlet associated with said generator for introducing a reactant gas;
- an inlet associated with said housing for introducing a cooling medium at not greater than about 0° C. between said housing and said generator;
- an outlet associated with said generator for withdrawing an ozone containing gas stream;
- an outlet associated with said housing for withdrawing said cooling medium;
- a recirculator associated with the housing inlet and housing outlet for recirculating at least a portion of said cooling medium;
- a converter associated with said housing outlet and said generator inlet for converting at least a portion of said cooling medium to a gaseous coolant;
- and
- means for introducing said gaseous coolant into said reactant gas.
