AIR QUALITY IS OUR MISSION
Ecospray specializes in the research, design and commercial
development of innovative technologies for gas cleaning and/or
cooling in diverse industrial applications.
Ecospray’s commitment to the environment extends to the marine
industry.
Having acquired an established history of expertise from over 400
installations worldwide, Ecospray offers a wide range of systems and
equipment specifically designed for the marine industry, including:

MEETING GLOBAL EMISSION
REQUIREMENTS
Ecospray provides a range of solutions specifically designed to meet
emission limit for both SOx (MARPOL 73/78 Annex VI) and NOx
(TIER III).
Ecospray systems also satisfy the more stringent local SOx, NOx and
particulate matter requirements of various countries and ports that
have been more progressively increasing their efforts to prevent the
harmful effects of emissions on the environment and human health.
Regarding wash water, Ecospray systems have been confirmed to
consistently result in effluent that is well below the regulated limits.

ECO-EGCTM MAKES THE DIFFERENCE
For the marine industry, Ecospray has developed the ECO-EGCTM, a proprietary multi-pollutant Exhaust Gas Cleaning system that guarantees
excellent air and water quality standards.
PRIMARY PERFORMANCE FEATURES:
- When combined with the ECO-CDFTM (Catalytic Dry Filter) or
ECO-DOCTM (Diesel Oxidative Catalyst reactor), both patented:
- PAH / OIL RESIDUAL often below the detection limits
- VIRTUALLY NO HEAVY METALS (with ECO-CDFTM)
- SIGNIFICANT REDUCTION of SOOT either in the wash water or in
the exhaust gas emission
- EXCELLENT WASH WATER QUALITY, also with ECO-EGC TM
OPEN LOOP system
- Due to its extremely compact design and highly effective noise
attenuation, the ECO-SOxTM ULTRA - COMPACT SEA WATER
SCRUBBER perfectly replaces the existing silencer and does not
require funnel modification.
- Ecospray’s proprietary “Triple swirl” demister eliminates sea water
carryover and drastically reduces the need for maintenance and
cleaning.
- The ECO-EGCTM process includes sea water injection that is
calibrated proportionally to the engine loads, in order to save power
energy and lowering operating costs.
- The exclusive design of the Ecospray ECO-SOxTM panelled scrubber
allows for installation while ship is in service versus waiting for the
next dry dock.
- An Ecospray proprietary condensation water catcher can be
installed on the top of the funnel to solve the common problem of
the condensation formed in cold weather inside the exhaust gas duct.
ECO-EGCTM OPEN LOOP SYSTEM
COMPONENTS:
ECO-EGCTM OPEN LOOP is a very cost/performance effective solution in
the cleaning of the exhaust gases of marine engines and in the continuing
use of HFO instead of MGO in ECA’s.
1. CATALYTIC DRY FILTER / DIESEL OXIDATIVE CATALYST REACTOR
This unique and patented solution consists of firstly cleaning the gases
from PM, soot and unburned HC with the ECO-CDFTM (Catalytic Dry
Filter) or the ECO-DOCTM (Diesel Oxidative Catalyst reactor).
Downstream of the CDF or the DOC reactor, the exhaust gas enters into
the ECO-SOxTM DeSOx tower.
Ecospray DeSOx towers use seawater only to neutralize the SO2 contained
in the exhaust gas. Their efficiency always meets and even exceeds
the IMO limits for both gas emissions and wash water quality thanks
to the installation of proprietary water spray nozzles and a very specific
configuration of the ECO-SOxTM DeSOx tower. They also help to optimize
the quantity of seawater injection at low engine loads.
The ECO-SOxTM DeSOx tower can operate either in wet or dry conditions.
The dry condition can be activated in port when the ship will switch the
fuel use from HFO to MGO.

ECO-EGCTM HYBRID SYSTEM
COMPONENTS:
The ECO-EGCTM HYBRID is a high performance solution purposely
designed and applied in order to meet specific requirements in terms
of wash water discharge, mainly in some port areas.
The ECO-EGCTM HYBRID system can operate in two different modes,
either in the open loop or closed loop mode.
In the open loop the SO2 removal is controlled by sea water injection
only, while in the closed loop the SO2 removal is controlled by the
addition of caustic reagent to the wash water.
1. CATALYTIC DRY FILTER / DIESEL OXIDATIVE CATALYST REACTOR
The ECO-EGCTM HYBRID system can switch from operating mode
“open loop” to “closed loop” activating first the reagent dosing
system. At the same time the shut-off valves located upstream of
the pumps are closed and the valves of the scrubber wash water
discharge are switched to send the water to the tank instead of to the
overboard.The system will then operate completely in closed loop.
A certain quantity of blow down water is sent to either one water
treatment system and then discharged overboard or sent to one
integrated holding tank in case “zero discharge” mode is required.
According to the holding tank volume, the system can operate in zero
discharge mode even for a few days before discharging the collected
blow down at a properly equipped port.
The closed loop recirculation liquid is kept duly cold to maintain the
DeSOx efficiency and minimize the steam white plume at the funnel.
Of course, the system can always start a reverse procedure from
closed to open loop mode.

ECO-SOxTM ULTRA
COMPACT SEA WATER SCRUBBER
Every DeSOx tower can be equipped with an exhaust fan whose speed
is automatically controlled in order to keep the engine backpressure
at the desired set point. In case of the mechanical or electrical failure
of the fan, the system is provided with a by-pass whose valve opens
automatically and the gas will flow to the funnel.
ECO-SOxTM ULTRA - COMPACT SEA WATER SCRUBBER is the key
component upon which revolves the Ecospray exhaust gas cleaning
system.
ECO-SOxTM ULTRA has a very compact design that allows to reduce
the installation costs and avoid any expensive funnel modifications.
The excellent performance of the ECO-SOxTM ULTRA is achieved
thanks to the installation of proprietary water spray nozzles and a
very specific configuration of the scrubber. It also helps to optimize
the quantity of seawater injection at low engine loads.
Further, the sea water flow rate is always controlled through the
engine load and feed-back received from the gas analyzer system
(SO2 / CO2 ratio).
In order to eliminate the acidic water carryover and black spots from
the funnel, a proprietary centrifugal demister is installed in the upper
part of the ECO-SOxTM DeSOx tower.
The fabrication material of the ECO-SOxTM ULTRA (super-duplex)
allows a high resistance to the acidic environment during both wet
conditions and the high temperature registered when operating in
the dry condition mode.

DeNOx SOLUTIONS FOR MARINE
APPLICATIONS
Ecospray has already installed over one hundred DeNOx systems
worldwide, ensuring continuous compliance with the global emission
regulations in several applications like power plants, cement, steel and
metals foundries, chemicals plants, as well as in waste incinerators.
Ecospray DeNOx systems for marine applications use SCR (Selective
Catalytic Reduction) technology to remove nitrogen oxides from
diesel engines exhaust gas complying with Tier III emission level but
also up to 98% if required in specific cases.
ECO-NOxTM SCR
The ECO-NOxTM SCR reduction process in the marine applications
usually begins by injecting downstream each gas turbine a 33% urea
solution into the gas flow at an optimum temperature between min
300 and max 400 °C.
ECO-NOxTM uses proprietary lances and nozzles to obtain a very fine
spray that allows achieving the most complete and uniform mixing
between gas and NH3.
The gas and reagent mix passes through a variable number of catalyst
layers, as is appropriate for the required outcome.
Ecospray installs a DeNOx catalyst produced by Haldor Topsøe A/S,
whose main active components are Vanadium and Tungsten oxides
plus TiO2 carrier.
ECO-TRIOTM DeNOx PLUS
ECO-TRIOTM DeNOx PLUS is an all in one system designed to allow
marine diesel engine from 150 to 4.300 kW achieving:
- NOx REMOVAL WITHIN TIER III LIMITS*
- PM and ASH REMOVAL > 95%
- TYPICAL NOISE ATTENUATION FROM 30 TO 40 dB
* If required, NOx removal over 95%
Clean gas outlet
Exaust gas inlet
Further to saving space because it replaces the existing silencer,
with ECO-TRIOTM DeNOx PLUS the following additional benefits
are achievable thanks to the oxidative combined effect of the
ECO-CDFTM CATALITYC DRY FILTER together with the DeNOx:
- REDUCTION OF PAH AND HEAVY METALS UP TO 95%
- ODOUR CONTROL
- NO VISIBLE SMOKE AT THE STACK
