Design
RSSS is a Company established 2014 with main goal to develop a scrubber by means of “Sequential co‐current flow”, where liquid and gas flows in the same upward direction and the liquid is reused in counterflow direction phases. (For other activities see engineering department activities )
The initial technology goal was to develop a exhaust gas sulphur washing system to be used in relation with ship engines burning diesel or HFO, with sulphur content higher than limits given in Marpol 73/78. annex VI.
Later designs have been developed to also work in the scrubbing stage of CO2 cleaning processes.
RSSS Scrubbers are useful in many applications where liquids are used for absorption of chemicals or partial gases in gas / exhaust flow.
Our design allows for:
- High exhaust gas velocity with low pressure drop
- Small dimensions and low weight
- High L/G relation
- High efficiency in gas absorption
- High efficiency in particle removal
- Reduced “carry over” liquid in gas outlet, due to efficient centrifugal separation of droplets

Liquid / Gas Relation
SO2 Cleaning:
- 3.5% / 0.1% (5 m3 water / kg SO2 L/G = appr 8.0
- 3.5% / 0.5% (3 m3 water / kg SO2 L/G = appr 5.0
CO2 Cleaning (by use of Amin):
- L/G = appr 0.8 to 1.5
- No additional scrubber section needed
Developement History
