Jet scrubbers
Properties and applications of jet scrubbers
Properties:
- no fixtures
- self-priming
- co-current operation of gas and scrubbing liquid
- flow rate fluctuation up to 1:8 permissible
- separation efficency 2-5 transfer units
- short contact time
- insensitive to caking and incrustations
- low foam formation (when using VUM separators)
- horizontal and vertical gas supply can be integrated into pipelines
- low space requirement
- variable (length, diameter, design etc.)
- cost-effective
- various materials possible, e.g. thermoplastics, GFK (also with liner), stainless steel, steel with liner (rubber coating), special materials (alloy, enamel), etc.
Possible applications for jet scrubbers:
- direct cooling
- Pre-saturation (quench head may be necessary)
- physical absorption
- Chemisorption with fast reaction or in combination with reaction distance (absorption with reaction, Ha < 3)
- Dust separation up to 1μm
- Condensation (also with high inert gas content)
- Pre-separation with high solids loading
- Combination of cooling, absorption and dust separation (e.g. for aerosol separation)
