| 1. | Spray towers have been used to remove these highly soluble compounds.
|
| 2. | Operating characteristics of spray towers are presented in the following table.
|
| 3. | Like a spray tower an ejector venturi scrubber uses a preformed spray.
|
| 4. | A spray tower is typically used for this application.
|
| 5. | Spray towers have been used effectively to remove large particles and highly soluble gases.
|
| 6. | Low energy devices such as spray towers are used to collect particles larger than 5 micrometers.
|
| 7. | Therefore, spray towers use nozzles that produce droplets that are usually 500 1000 �m in diameter.
|
| 8. | For example, spray towers are used to remove HCl gas from the tail-gas exhaust in manufacturing hydrochloric acid.
|
| 9. | These devices are used much the same as spray towers-to preclean or remove particles larger than 10 ?m in diameter.
|
| 10. | In order to maintain low gas velocities, spray towers must be larger than other scrubbers that handle similar gas stream flow rates.
