The following are some of the Downflow Gas Contactor’s properties and advantages:
- Stable bubble matrix formed
- Distinct gas-liquid interface
- Lower power consumption
- Smaller operating volume
- No foaming
- No free gas-liquid interface
- Inherently safe
- 100% gas utilisation
- Greater than 95% approach to equilibrium in very short contact times
- High and accurate control of interfacial areas
- Improved reaction rates and selectivity
- No internal moving parts
- Reduced capital and operating costs
- Higher gas hold-ups (50-60%)
- Tolerance to particulates
- Easy scale-up without loss in efficiency
- Easy automation and control
- Batch, semi-autonomous or continuous mode operation
Some videos of the DGC reactor
In this video (DGC Column) you see a bubble column developing within a DGC reactor. Here are some details about what you see at various times within the video.
Time | Description |
7 seconds | Start-up of DGC Gas input into flowing reaction media with catalyst |
18 seconds | Bubble column develops |
35 seconds | Gas input reduced – bubble column height reduces as reaction occurs with Gas utilisation, till equilibrium level attained |
59 seconds | As Gas input increased bubble dispersion column develops again |
In these videos you will see bubble dispersion maintaining level in the DGC column with 100% gas absorption at continuous flow conditions; greater than 95% equilibrium concentrations are achieved.
