Clean Emissions

Renewable energy sources such as solar and wind are the most sustainable solutions for power and transportation.  But for many applications, such as trans oceanic shipping, electric energy storage is not practical.  Combustion of fuels remains the only practical energy source for these applications.  Our mission is to apply innovative technological solutions to clean exhaust gases to remove harmful emissions such as sulfur oxides, nitric oxides, particulate matter, and green house gases including carbon dioxide.   

Our engineers have more than a century of combined expertise in reducing emissions for the power generation, chemical, road, rail, air and marine industries.  We are here to help you find the best sustainable solution to reduce your emissions.


Carbon Capture

Ionada’s membrane technology is the ideal technology for carbon capture for marine and power generation. Ionada’s membrane CO2 contactors can remove up to 99% of the carbon dioxides flue gas. Our CO2 decarbonization system is the most sustainable and environmental solution for carbon reduction.

Up to 99% CO2 Capture

30% more energy efficient

lowest carbon footprint

Modular containerized design, ideal for retrofit installations

Zero water consumption

Reduced landfill costs with regenerable absorbent solutions

Proven and reliable CO2 absorbents

Ionada’s Membrane Decarbonization system combines proven chemical absorption processes with porous ceramic tube membranes to remove carbon dioxide from flue gas without creating a throwaway sludge product.

Carbon dioxide is separated from exhaust gas and captured by an absorbent solution passing through hollow ceramic membranes made of alumina.

This material provides high absorption efficiency and durability in the hot and corrosive exhaust environment, and has an estimated minimum service life of 10 years.

Ionada’s membrane CO2 absorber utilizes proven amines absorbents for the removal of gases from the exhaust gases. Cold Amines solutions are circulated  in the membrane contactor to bind CO2. The binding is reversed at higher temperatures.


Sequestering,  CO2-enhanced oil recovery, tertiary recovery methods.  Ideal locations are oil reserves greater than 2,500 m in depth. 

DeSOx Dry Desulfurization

Pollutants emitted from combustion are associated with human health and environmental risks. Acid deposition, or acid rain as it is commonly known, occurs when SOx and NOx react in the atmosphere with water, oxygen, and oxidants to form various acidic compounds that later fall to earth in the form of precipitation or dry deposition of acidic particles. They contribute to the damage of trees at high elevations and in some regions lakes and streams may become so acidic that they cannot support aquatic life. In addition, acid deposition accelerates the decay of building materials and paints, including irreplaceable buildings, statues, and sculptures that are part of our collective cultural heritage.  We all will benefit from reduced air emissions with an improved ecosystem and human health.

Dry Desulfurization removes 99.9% of all sulfur oxides from flue gas. Dry injection of sodium bicarbonate powder into flue gas and the resulting sodium sulfate powder byproduct are both non-hazardous, food safe, pH neutral, non-pollutants. Dry Desulfurization systems are carbon neutral with lower total carbon emissions than sea water exhaust gas cleaning systems and low sulfur distillate fuels. Dry Injection Desulfurization (DID) provides a viable, sustainable and environmental solution to reduce harmful emissions.

Particulate Matter

Particulate Matter or PM is defined as complex mix of very small particles, water vapor, and gases. SOx and NOx are examples of particulate matter that have especially harmful effects on the environment. EPA and EU regulates two categories of particulate matter for health and welfare reasons:

PM10: “Inhalable coarse particles” are between 2.5 and 10 micrometers in diameter
PM2.5: “Fine particles” are smaller than 2.5 micrometers in diameter 

These fine particles pose more health risks than larger particles because they can settle deeper into the lungs and even into the bloodstream. Like other air pollution, particles can cause premature death in people with heart or lung disease, nonfatal heart attacks, irregular heartbeat, aggravated asthma, decreased lung function, and respiratory issues like inflamed airways and difficulty breathing.

Ionada can offer a variety of technologies to reduce  Particulate Matter including impulse cleaning Bag Filters, Elec­tro­sta­tic Pre­cip­i­ta­tors, Cyclone Sep­a­ra­tors as well as passive Diesel Particulate Filters for smaller engines.

Ionada utilizes SCR (Selective Catalytic Reduction) tech­nol­ogy as a means of re­duc­ing pol­lu­tants such as NOx, NH3 and or­ganic com­pounds.  SCR technology can achieve ex­cep­tion­ally low NOx emis­sion val­ues.

Ionada offers solutions to maximize performance while meeting EPA Tier 4 and IMO III emission regulations.  Ionada’s SCR technology can improve on engine packages, while allowing systems to remain compact and easy to service, helping improve overall fuel economy.
