A method for cleaning polluted cleaning liquid including a polluted marine exhaust gas cleaning liquid;
- said method comprising the steps of:
- a) providing said polluted cleaning liquid;
- b) adding a solid porous adsorbent to said polluted cleaning liquid;
- c) allowing said adsorbent to react with pollutants of said polluted cleaning liquid;
- d) subjecting the polluted cleaning liquid to separation in a centrifugal separator;
- and
- e) discharging a clean liquid phase and a pollutant phase from said centrifugal separator.
A system system for cleaning polluted cleaning liquid, wherein the polluted cleaning liquid is a marine exhaust gas cleaning liquid, said system comprising:
- a centrifugal separator arranged for separating at least one polluted phase and a clean phase from said polluted cleaning liquid,
- a dosing unit comprising solid porous adsorbent and arranged upstream of said centrifugal separator for addition of said solid porous adsorbent to said polluted cleaning liquid, and
- a transporter for transporting the polluted cleaning liquid to which said adsorbent has been added to said centrifugal separator.
