SCURRUBER

Easy installation : Open Loop > Hybrid

LOW cost required : Open Loop > Hybrid

Depends on the ECA :

   Open Loop (0.5%)        Closed Loop(0.1%)      Hybrid

 

Reference :

  Open loop 0.5% Sulphur – sea water only when – Sulphur < 3.5% 

  (Given that exhaust gas largely comes from Diesel engine)

 

Open loop 0.1% Sulphur – sea water + NaOH dosing;

   can transit any water – no alkalinity restrictions

 

Closed loop – sea water + NaOH dosing; only required

   – where zero discharge is called for pH

    Open loop 0,5% Sulphur – process water + dilution device

    Open loop 0,1% Sulphur – plus NaOH (pH 6,5 at 4m or pH 6 – overboard)
