Ammonia-based desulfurization process and apparatus through ammonia-adding in different chambers |
| abstract |
The present invention discloses an ammonia-based desulfurization process through ammonia-adding in different chambers, wherein an oxidation section comprises an oxidation chamber and an ammonia-mixing chamber in fluid communication with each other, and an ammonia absorbent is added to the ammonia-mixing chamber. Preferably, the absorption-oxidation cycle of the process comprises liquid circulation between the oxidation chamber and a secondary spray absorption section and liquid circulation between the ammonia-mixing chamber and a primary spray absorption section, and there is a communication between the two circulations at least through the fluid communication between the oxidation chamber and the ammonia-mixing chamber. The present invention further discloses an apparatus for implementing the process. |
