SOx scrubber for vessel exhaust
A proven process adapted to maritime transport
Taking a proven solution from land to the seas
Serving more than 500 satisfied customers for flue gas treatment on land and considering the new requirements of the International Maritime Organization (IMO) regulations for 2020 and beyond, SOLVAir® has extended its portfolio with a sodium-based dry scrubber solution to clean exhaust gases from vessels running on High Sulphur Heavy fuel Oil (HFO) diesel engines.
A continued focus on sustainability
The project was carried by experienced and passionate engineers and managers, and received full support from the SOLVAY Group.
Sustainability is at the heart of Solvay’s strategy and the SOLVAir® Marine dry scrubber is a truly sustainable solution we are proud to develop and promote for the marine industry.
What can SOLVAir® Marine do for you?
Till 100% of SOx removed, and more
The SOLVAir® Marine flue gas treatment solution will help you achieve desired removal rates for SOx. It also offers an unmatched particle removal rate of 99%.
A dry process for more sustainability
With SOLVAir® Marine’s solution, no effluents are released into the sea and residues are treated on land.
A non-toxic product for more safety
The sodium-based sorbents used in our exhaust gas cleaning system are non-corrosive, non-irritant, and non-toxic. They are therefore safe to handle, which will make life easier for operators.
Easy installation, no dry docking
Installing the SOLVAir® dry scrubber is quick and doesn’t require dry docking. There are also significant synergies with Selective Catalytic Reduction (SCR) Denox.
No heavy investment required
No energy for pumping wash water is needed. Moreover, this is an adaptable solution that allows vessels to sail in and out of areas having different SOx regulations without changing their fuel type.
How does our flue gas treatment solution for vessels work?
- The sodium sorbent is loaded onto the ship and stored in silos onboard.
- During operation, the sorbent is injected into the vessel’s exhaust gas. The sodium sulfate residue resulting from a reaction with the SOx in the exhaust gas is filtered out in the vessel’s funnel - along with other particles such as micro pollutants, soot, etc.
- The residue is collected and stored in the onboard silos, until it’s disembarked to be treated on land.
SOLVAir® Marine is supported by Solvay’s global reach
Dry Scrubber & Wet Scrubber
What is the difference between a dry scrubber and a wet scrubber?
A “wet scrubber” is a process that uses sea water in a scrubber tower to reduce a vessel’s pollutant emissions. In this scenario, the used water containing sulfates and other elements (metals, soot…) is released back into the sea (in an “open loop” system) or stored on the ship (in a “closed loop”).
A dry scrubber, at it name implies, doesn’t use any water. SOLVAir®’s dry system is a flue gas treatment solution that uses a sodium-based sorbent that removes up to100% of SOx and over 99% of particles. No waste, residue or pollutants are released into the air or the sea thanks to SOLVAY’s residue treatment process on land.
Why choosing a dry scrubber?
It offers a higher particle removal rate (over 99%) than a wet scrubber
No dry docking required for installation
It can be combined with Selective Catalytic Reduction (SCR) DeNOx for significant synergies
Lower CAPEX and OPEX
Lower sensitivity to failure
Less labor required for maintenance and operation
It’s safer, thanks to the non toxicity of the sorbent
No effluents are released into the sea
Residues can be treated on land
Let's play! SOLVAir® is a flue gas removal process as easy as 1-2-3!
