The ECO-EGCTM OPEN LOOP system, uses only seawater to neutralize the SO2 contained in the exhaust gas. The efficiency of the system always meets and even exceeds the IMO limits for both gas emissions and wash water quality, without limitations of sulfur content (up to 3.5%). 
The inline DeSOx tower can operate either in wet or dry conditions. The OPEN LOOP system represents the most cost effective solution in terms of CAPEX and OPEX in order to comply with sulfur regulations using fuels different from the compliant one.
As an option Ecospray can provide a unique and patented solution that consists of cleaning the gases from PM, soot and uncombusted HC with the ECO-CDFTM (Catalytic Dry Filter) or the ECO-DOCTM (Diesel Oxidative Catalyst reactor).
