Ecospray Technologies S.r.l. products

The ECO-EG™ OPEN LOOP system uses only seawater to neutralize the SO₂ contained in the exhaust gas, without the use of chemical agents.

The ECO-NOx for marine applications is designed to be adapted to limited spaces on board and is suitable for propulsion engines and gensets from 1.6 MW to 16 MW, both for vertical and horizontal installation. The NOx reduction process begins by injecting urea solution (33% or 40%) before the SCR reactor into the gas flow with proprietary self-cleaning urea spray nozzles. The gas and reagent mix passes through a variable number of catalyst layers, as it is appropriate for the required emission level.

With the ECO-EGC systems, SOx removal can be combined with an exhaust gas pre-treatment through a patented catalytic filter, ECO-CDF (Catalytic Dry Filter) or ECO-DOC™ (Diesel Oxidative Catalyst reactor), installed downstream of the engine.

ECO-NOx SCR catalytic systems, with injection of urea (at 33% or 40%) or ammonia (at 25%), provide abatement performance up to 99% in the gas flow at preferably 300 -400°C. Plants are composed with modular reactors to adapt to any gas flow / performance requirement, and are suitable for retrofitting and new installations.

Acid gas abatement systems employing scrubbers with nozzles of proprietary design: wet scrubbing technology based on the neutralization of the acid gases (SOx, HCl, HF, etc.) with the injection of fresh water plus a reactant (NaOH-NaHCO³-Na²CO³-Ca(OH)²) or sea water only in the marine applications.

We can offer baghouse filters, both fabric and ceramic, for medium-low gas temperatures and for high-temperature applications. Baghouse filters for low temperature applications are designed to maximize their reliability, efficiency and are long lasting in all working conditions. Volumes of gas to be treated go from 1,000 up to 1,000,000 m³/h. High temperature dedusting systems are equipped with ceramic candles able to operate up to 800° C. The catalyzed ceramic filters, on the other hand, combine the removal of particulate matter and NOx thanks to the addition of catalysts.

The multi-pollutant axial flow filtration cassettes (Wall flow / Flow through) combine the oxidation of CO (thanks to special oxidative catalysts) with the particulate removal and NOx abatement. These cassettes are suitable for any industrial applications (for example, engines, cement industry, urban solid waste). Ecospray filters consist of a reactor that houses the axial flow elements which combine the oxidation of CO, high efficiency filtration (antiparticulate) and the removal of NOx (SCR).

These systems are designed to distribute the demineralized water inside the air flow with semi-rounded arrays, swirl nozzles and high-pressure pumps. For turbines with power 30 ÷ 270 MW an increase of output power of 3 MW ÷ 18 MW can be achieved.

These systems can be installed externally of the air intake and are equipped with proprietary filters that retains all the spray droplet. For turbines power output 3 MW ÷ 20 MW an increase of output power of 0.5 MW ÷ 2 MW can be achieved.
