| 1. | In addition, they operate with low liquid-to-gas ratios.
|
| 2. | The gas velocities are lower and the liquid-to-gas ratios are higher for absorption.
|
| 3. | A smaller average solid to gas ratio is then necessary to suppress turbulence at the mid-plane.
|
| 4. | Solubility governs the amount of liquid required ( liquid-to-gas ratio ) and the necessary contact time.
|
| 5. | For a given temperature and process pressure, oxide growth rates are fixed if the gas ratio is also constant.
|
| 6. | A high average solid to gas ratio may be reached due to the loss of gas or by the concentration of solids.
|
| 7. | Particle collection efficiency increases with an increase in nozzle pressure and / or an increase in the liquid-to-gas ratio.
|
| 8. | The liquid-injection rate, or liquid-to-gas ratio ( L / G ), also affects particle collection.
|
| 9. | This reduces the solid to gas ratio at the mid-plane to less than 1, suppressing the formation of dense clumps.
|
| 10. | At higher average solid to gas ratios the mass of solids dampens this turbulence allowing a thin mid-plane layer to form.
