Oxidizer and oxidation process for a desulphurization process
View Patent ↗An improved oxidizer for liquid reduction-oxidation desulphurization processes uses a hollow fiber membrane contactor. A pressurized, oxygen containing gas stream is introduced into the interior of the hollow fiber membrane while a liquid reduction-oxidation catalyst solution contacts the exterior of the membrane. Oxygen diffuses through the membrane into the liquid reduction-oxidation catalyst solution whereby the solution is oxidized and can be recycled for further us in a desulphurization process.
1. A process for continuously oxidizing a liquid reduction-oxidation catalyst solution comprising the following steps in combination:
a. providing a contacting unit comprising a hollow fiber membrane having an interior and exterior;
b. introducing a stream of pressurized, oxygen containing gas to the contacting unit; and
c. introducing a liquid reduction-oxidation catalyst to the contacting unit such that the oxygen contacts the catalyst.
2. The process of claim 1 further characterized in that the pressurized, oxygen containing gas is directed to the interior of the membrane and the liquid reduction-oxidation catalyst is directed to the exterior of the membrane.
3. The process of claim 1 where the liquid reduction-oxidation catalyst is a chelated metal solution.
