SETH™ - Engineering solution to reduce pollution in urban areas near ports.

Introducing SETH™, a patented, state-of-the-art technology to capture and reduce air pollution from oceangoing ships docked in ports to near zero. Air pollution constitutes both a health and an environmental problem that by U.S. Environmental Protection Agency estimation, costs the U.S. hundreds of billions of dollars per year. Please watch the video below to learn how our system is the best solution for this problem.

There are many different type of vessels and berth configuration in the maritime sector but we can say in general that the pollution problems within ports are the same relative to fuel-oil combustion. SETH™ offers a standardized solution of pollution mitigation services for ports that do not require retrofitting or costly modifications to both the port infrastructure or ships in general.

The Maritime Sector

Our Innovation / ECD – Emission Capturing Device

Patented U.S./E.U.

Our patented technology enables the capture of maritime exhaust while adding controls to the gaseous stream without the need for difficult retrofitting. Our capturing device can create a sealed connection with existing exhaust stacks and, through a system of controls, prevent the formation of backpressure, allowing the gaseous stream to be safely rerouted to aftertreatment systems while conserving the exhaust’s temperature. This device is crucial for waste heat recovery and power generation from exhaust gases.

Complementary to Shore Power

SETH™ systems are implemented as a dockside service. It is not an alternative to Cold Ironing, it is complementary where cold ironing exists to offer assistance to vessels that may not be compatible. The system does not require any retrofitting and it is widely compatible with any type of vessel.

At Greener Process Systems we combine the process knowledge and resources of an engineering firm with equipment fabrication and supply capabilities tto provide a suite of quality engineering services with SETH™.

SETH™

Air Pollution Reduction System for Ships Docked in Ports
(patented E.U., patented U.S.)

Download: Pollutant Emissions in Ports: A Comprehensive Review ( 2021)

A single SETH™ system simultaneously removes different types of pollutants present in ship exhaust (NOx, SOx, PM, Heavy Metals). The catalytic process abatement efficiency is extremely high (>95% on average). The system takes advantage of a dry process without the use of any solvents or any liquid, and so no liquid waste is generated from it, which can result in water contamination (see scrubbing system failures).

Advanced robotics make this system highly adaptable and versatile designed to reach multiple ship’s exhaust funnels simultaneously independently from their shape and form. The system is fully automated and does not require direct human intervention.

SETH™ utilizes different solutions to accommodate each port necessity without interfering with normal operations. Features Smart Eco-Barge when the risk of interference with the harbor operations must be avoided (cargo, container ships, etc.) and Smart Eco-Berth when the occupation of part of the quay doesn’t create any interference with the normal harbor operations.

SMART ECO-BARGE

The Smart Eco-Barge is a compact and versatile solution that is suited for any port where the space available on the doc to place the Emission Treatment Device ( ETD ) & conduits is limited. The entire system is fitted into a barge, and it can reach ship exhaust almost anywhere while docking or anchoring.

DRY WASTE DISPOSAL

The dry waste, classified as harmless special industrial solids, is stored in the Emission Treatment Device’s ( ETD ) waste bins that can be unloaded periodically for disposal by local waste management companies.

SPECIAL FEATURES

•Equipped with 2 Electrical Engines
•Air-cooled (does not contribute to water warming)
•Power source available as Full-Electric or Hybrid. Full-Electric systems are equipped with swappable batteries. Hybrid systems are equipped with power generators that have exhaust connected to the Emission Treatment Device ( ETD )
•Spatial recognition and fully automated (it positions itself)
•Rapid Release – does not interfere with normal port operations
•Low Noise Fan and Ventilation (under 80db)

ABATEMENT DATA

•NOx removal effectiveness 90%
•SOx removal effectiveness 95%
•Diesel Particulate removal effectiveness 98%
•Heavy Metals removal effectiveness 98%
•The system also breaks down CO2 as a secondary reaction of the neutralization of SOx by means of alkaline sorbents. •CO2 abatement in average conditions (for small tonnage ships) is about 100 tons/year/ship*. CO2 abatement in average conditions up to 1000 tons/year/ship* (for medium tonnage ships).

*The values can change according to the temperature of the fumes given to the treatment and the size of the vessel power source.

SMART ECO-BERTH

The Smart Eco-Berth is a system configuration perfect for larger ports where the emission treatment device (ETD) the ductwork and the emission capturing device (ECD) are installed on the dock site. The ETD can be proportionally sized to serve several ECD and multiple docking stations to capture and treat the emission of multiple stationing ships.

DRY WASTE DISPOSAL

SPECIAL FEATURES

•Equipped with WHR unit ( Waste Heat Recovery ) capable of generating upto $200/hr of operation
•Equipped with railings for ductwork to extend and adjust the positioning of derrick along the dock

Pollution in Urban Areas Near Ports Has Reached Critical Levels.

Greener Process Systems Inc. has developed a patented state-of-the-art technology to capture emissions and reduce air pollution from ships that are docked in harbors (SETH™) – many of which are located in and around major cities throughout the world. Air pollution constitutes both a health and an environmental problem. 70% of pollution caused by stationing ships docked in ports ( Source APAT 2005 Review, Ports of Reference Naples, IT 63% – Cagliari, IT 77%) includes fine particulate matter, including sub-micron nuclei mode, nitrogen oxides (NOx), air toxins, heavy metals, and VOC. On average, one large ocean-going ship emits the equivalent of more than 20,000 cars not equipped with catalytic converters ( As per Transportation and the Environment ).

How Do Ships in Port Contribute to Air Pollution?

Ports are a vital part of the United States & world economy, with seaports, Great Lakes ports, and inland river ports serving as gateways for moving freight and passengers across the country and around the world. As nations adopt to meet economic and infrastructure demands, it is critical to understand the potential impacts on air pollution, greenhouse gases (GHGs), and the people living, working, and recreating near ports. Diesel engines are the modern-day workhorse of the shipping economy, and although they can be reliable and efficient, older diesel engines can emit significant amounts of air pollution.

A vessel’s diesel engines run on HFO (heavy fuel oil), IFO (intermediate fuel oil), LSMGO (low sulfur maritime gas oil), VLSMGO (very low sulfur), ULSMGO (ultra-low sulfur), showing a decrescent content of sulfur. Currently, the regulations in force stated that, while in harbors, the ships must feed the diesel engines with LSMGO and this is a good thing since, by doing so, the ships emit less sulfur dioxide.

In developed countries, SO2 emissions have been dropping so that now SO2 pollution is rare in urban environments. The main SO2 source remaining is from ships stationed in port. Unfortunately, however, LSMGO doesn’t prevent the formation of several other pollutants. In fact, NOx, PM, heavy metals, VOCs are emitted as if the ship would use the worst fuel, and that is HFO. Moreover, due to the remarkable difference in cost and in availability, LSMGO has limited use.

Why Should We Care About Ship Emissions?

Major air pollutants generated by port activities include, volatile organic compounds (VOCs), nitrogen oxides (NOx), sulfur oxides (SOx), and particulate matter (PM). Millions of people throughout the world live close to ports and the health effects compounds can include premature mortality, increased hospital admissions for heart and lung disease, increased cancer risk, and increased respiratory symptoms – especially for children, the elderly, outdoor workers, and other sensitive populations. A recent study found that emissions from diesel engines, commonly used in the freight industry, are significantly more harmful to humans than those from petrol vehicles and more than 30 human epidemiological studies have found that diesel exhaust exposure directly increases cancer risk. Port-related diesel emissions—such as NOx and black carbon—also may contribute to climate change.

“I have spent the last 35 years of my career dedicated to making the earth a cleaner place to live. And I am proud of the technical achievement with SETH that will surely lead to a cleaner environment, less greenhouse gases and healthier air for all of us to breath.”
