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
