According to MARPOL 73/78 'International Convention for the Prevention of Marine Pollution by Vessels', the International Maritime Organization (IMO) has agreed that all vessels operating in SECA (Sulfur Emission Control Area) have been required to use fuel with the sulfur content of 1% or less since July 2010 and to use fuel with the sulfur content of 0.1% or less since 2015. Moreover, globally 0.5% or less in all oceans throughout the world is to take effect in 2020. In order to meet the requirements for permissible sulfur content in ship fuels, it is necessary to have a low sulfur content fuel or to have a desulfurization system that can meet regulatory requirements. Low sulfur fuels can be implemented in the short term. It will be the scrubber system that will meet regulatory requirements while using proprietary sulfur fuels.
Hyundai Materials EGCS
Hyundai Materials scrubber has a compact size that can minimize installation space constraint. Back pressure is minimized with its simplified internal structure(non-packing type). Based on the proven technology in stationary pilot test facility as well as in actual real ship tests, we have ensured optimal desulfurization efficiency and verified the problems that can occur in the ship with our proven solutions.

Benefits of Hyundai Materials EGCS
The slim design of our marine scrubber makes it the right choice for a retrofit. The reduced volume of our scrubber will allow to fit in the vessel without additional layout changes
Our scrubber system does not include venturi and pack beds, instead of pack beds, we applied distributors and variable nozzles to achieve low back pressure, cost efficiency and easy maintenance.
Hyundai Materials has optimized the scrubber performance through case studies on stationary pilot test bed and installed it on a marine engine (7MW) to ensure reliability and stability through demonstration.

Hyundai Materials Exhaust Gas Cleaning System, which removes sulfur oxides for the marine environment, is mainly classified into Open Mode, Close Mode, and Hybrid Mode. In Open Mode, Sea water is used as Wash water, in Close Mode, Alkali solution is used as Wash water and in Hybrid Mode, mode switch between Open Mode and Close Mode is available.
Open Loop EGCS
In Open Mode, Sea water is used as Wash water. Natural features of sea water removing sulfur dioxide are the main mechanism of Exhaust Gas Cleaning Process. In Open Mode System, Sea water is provided by Sea Water Supply Pump.Operation for sea going(normal operation)
Closed Loop EGCS
Close mode system circulates wash water in wash water tank. Wash water is supplied to the scrubber by the wash water pump through the cooler. The used wash water coming out from the scrubber is collected back into the wash water tank and reused.Operation low alkali zones & zero discharge zones
Scrubber is divided into I-Type and U-Type. Depending on the configuration of main engine, aux. engine and boiler etc., I-Type is classified into single stream system and combined stream system and U–Type is composed of single inlet and multi inlet System. Considering installation spaces and bypass system requirements, we provide 2 types of scrubbers for each condition.

SCR System Overview
SCR is an after-treatment technology that selectively reduces nitrogen oxides (NOx) from the emission.
NOx is converted to nitrogen (N2) and water vapor (H2O) which is harmless to human body by a reducing agent and catalyst. Ammonia or urea is mainly used as the reducing agent. Since January 1, 2016, the International Maritime Organization (IMO) has entered into an agreement 'Tier III' to reduce the emission of nitrogen oxides from diesel engines by more than 80%, and SCR must be installed to marine engines to comply with the Tier III standard. Hyundai Materials is able to manufacture and supply all SCR products from small engines to large engines, and provides solutions that meet customers' requirements and environmental regulations.

SCR System Components
It consists of De-NOx catalysts and housing including thermocouples and differential pressure transmitter to send the signals fo gas temperature and differential pressure throughout the catalyst.
USU (Urea Supply Unit)
USU has two pumps including a standby pump. It supplies urea 40% solution from the urea tank to UDU. It has a local panel to shut down at local area for emergency and maintenance.
UDU (Urea Dosing Unit)
UDU consists of control valve and flowmeter, some instruments / valves and it is a PID control type and communicates with control panel. It serves a high accurate / dynamic response to variation of engine loads.
It is operating based on input signal from the engine controller and signal communicate with other devices(SCR chamber, UDU, USU). Control panel ensures accurate response for NOx reduction.
Hyundai Materials offers an solution which is an engine-integrated Compact SCR system.
Usually, the SCR chamber is very large and contains a lot of separate components, so it requires a lot of space. For this matter, Hyundai Materials offers an solution which is an engine-integrated SCR system.
Compact SCR is optimized for small, high-speed engines. Due to a single type metal catalyst instead of the conventional honeycomb catalyst, the size is compact and the system is simplified. In addition, high-speed engines require high catalytic performance at high temperatures due to their high gas temperatures. Hyundai Materials has developed and applied high-temperature-only catalysts to achieve a reduction efficiency of over 90%.

Hyundai Materials has developed a new type of metal catalyst that overcomes the weakness of the conventional ceramic extruded catalysts. The catalyst materials is coated on a stainless steel structure, and because of its thin wall thickness, unit cell has very high porosity. Even if it has the same volume as ceramic catalyst, its surface area is high compared to honeycomb structure, which makes possible to build a compact system. In addition, since the structure is made of metal, it has excellent durability and does not break easy as the honeycomb catalyst does, and it is very advantageous in back pressure because of its high porosity.

Metal substrate catalyst is superior to ceramic catalyst in terms of increased specific surface area, porosity, strength, and stability against heat.

S-DPF (SCR on DPF)for both NOx & PMWhen particulate matter and nitrogen oxides are simultaneously reduced in the exhaust gas, it is common to separately install a DPF to reduce PM and SCR catalyst to reduce nitrogen oxides (NOx).
In this case, a large amount of installation space is required. To solve this problem, Hyundai Material has developed sDRF (SCR on DPF), a hybrid type integrated filter catalyst, which the SCR catalyst is coated on DPF filter. The volume is reduced by more than 35%, and the reductant injection device for SCR reaction is also applied inside the chamber, which simplifies the system configuration.
Suitable for All types of Fuels(incl. HFO)
Suitable for Low Sulfur Fuels
Hydrocarbons, carbon monoxide, and methane can be reduced through oxidation catalysts (DOC) that contain precious metals. In addition, to reduce soot, the NO in the exhaust gas is oxidized to NO2 to remove carbon trapped in the filter. In addition, when the NO2 content is increased, the SCR reaction rate is increased since NO2 causes fast SCR reaction as a result the De-NOx performance is enhanced by the DOC. Moreover for Methane (CH4), which is known as a representative greenhouse gas, is generated in the case of an engine using natural gas as a fuel.(Gas engines & Dual fuel engines) The Oxidation catalysts also functions to reduce methane.
|Carbon Oxidation(CO)||THC(Total Hydro Carbon)||Methane(CH4)|
|Carbon monoxide is a gas formed in an unstable state of carbon and oxygen and it is classified to a harmful gas because it reacts with hemoglobin and causes an addiction to the human body. When the heat and oxygen needed for the reaction are supplied, it becomes an harmless and stable molecule called carbon dioxide through the oxidation catalyst.||Hydrocarbons are emitted as unburned hydrocarbons from fuels, or by generated during the chemical reaction from combustion. When reacting with oxygen and nitrogen compounds, it becomes aldehyde which is a toxic substance to human and becomes a source of photochemical smog.||Methane is classified as a greenhouse gas because it has a long remaining time and absorbs infrared rays, and the amount emitted from carbon dioxide is very small, but the Global Warming Potential of methane is 21 times that of carbon dioxide per unit volume. Methane is closely related to the fuel composition and is produced in the engine by incomplete combustion, and in particular, a large amount of LNG gas is released as a slip.|
