The source of pollution is the use of resources, mixing and combustion and releasing the byproducts back into Nature. In essence, we are taking fundamental chemicals and materials that Nature has refined for us through solar energy and combining them in new ways. This combination results in what we perceive as pollution. Chemicals and compounds distributed where they should not be. An ideal sustainable situation would be if we were able to separate the consumed materials back into their original form and re-use them; or return them to their original place in Nature, if technology no longer requires them. Since the Industrial Revolution, nonrenewable resources have been consumed at the highest rate possible, without regard to environmental impacts. With the new IMO regulations, a step has been taken in the right direction. Ships can no longer distribute NOx and SOx particles freely in residential areas. They must separate those harmful contaminants from the exhaust, and distribute the particles into the sea where it is better absorbed without damaging the environment.


Currently, 60% of global ports are covered by these regulations, and it is intended that they will apply to 100% of global ports in the new future. This puts pressure on the 60,000 ships that are using heavy fuel oil with up to 3% Sulphur (SOx) content. The main issue is the separation challenge. To separate SOx, NOx and other particles the exhaust must be showered with salt water, which reacts with and captures particles. These contaminated water droplets must then be captured and separated from the clean exhaust before the contents are discharged. The contaminated sea water must be collected and distributed in the open sea, far from harbours. The process can consume between 20-30 tonnes of water per hour. The sheer volume and weight required for the efficient separation of exhaust fumes comes with a steep price tag. So steep that for many, if not most shipowners, this simply will not be profitable.


Several consortiums and companies are developing solutions that are installed and tested in full scale. Unfortunately these solutions rely on conventional separation systems where gravity is the main force for collection of the contaminated water. This is the critical limiting factor for separation in ship exhausts and the critical problem that InnSep AS, in collaboration with the Norwegian University of Science and Technology, has decided to solve. The solution is simple: the use of centrifugal force to capture the separated byproducts. Unlike gravity, centrifugal force is not constant, we can increase it indefinitely. Higher collection force equals less volume required for the separator. In the laboratories, successful trials have been performed which resulted in the required efficiency for separation being achieved with an 80% reduction of separator footprint and volume. This technology was developed for the oil and gas industry for more efficient oil production and protection of compressors, pipes and sensitive equipment. The same principle was also developed for the restaurant industry for collecting cooking fats, oils and liquids in the air before they are ventilated. In the US alone an estimated 6,200 fires happen every year in restaurants due to ignition of deposited oils in the ventilation systems.


Now we are planning to develop this separation system for the global shipping industry. Funded by the the Research Council of Norway (, a preliminary investigation has been performed outlining the challenges and possible solutions. The conclusion is twofold: This new principle can be used for all separation issues for ship exhaust gases. Secondly, the principle can be developed for retrofit on existing ships’ separator systems that are not performing optimally. In 2016 the first groundwork will be set for actual product development of this principle. Shipowners and providers of ship exhaust gas cleaning systems are invited to collaborate with InnSep and NTNU department of Energy and Process Engineering to take the final step towards efficient and sustainable ship exhaust separation.

Lynx Kitchen – Lynx Separator for foodservice industry

Lynx kitchen system collection chamber

InnSep AS has started R&D process for tailoring the The Lynx Separation system to solve the problems of cooking grease and residue building up in ventilation ducts and systems in the food service industry. The industry is facing stricter air quality regulations due to the type of contaminated air produced by cooking food. Without an air cleaning component, cooking grease, smoke and  residue build up in the ducts, blower, roof and outside walls of the building. It also clogs conventional filters used to remove cooking odors and particles. This residue is highly flammable and frequently causes fires. Conventional filtration technology is struggling to keep up, requiring larger and more advanced installations, driving up costs for the restaurants and end users.


Preliminary testing has concluded with good results. Using the Lynx Separation system for kitchen exhaust, fatty particles and liquids are efficiently removed and collected in a separate chamber for quick and frequent removal. The compact Lynx system enables conventional filtration systems to work with cleaner air and less liquids before exhausting outside the building.

Developing the Lynx Separator for Cleaning Ship Emissions

Oil Marketing & Trading International magazine profiled the Lynx Separation system for cleaning of Ships Exhaust in their news update. The article is more in-depth and covers the development stages of the technology and how the R&D is focused on achieving solutions to meet the challenges of the new emission standards. Currently, as many as 60 per cent of the world’s ports have voluntarily joined forces and agreed that they will refuse access to ships that fail to comply with the emission standards. By 2020, this restriction will apply to all ports. Given this outlook, many smaller and larger vessels are now on a desperate hunt to find new technology that will remove polluting particles from their exhaust emissions.

Lynx successfully cleans diesel exhaust gas

Exhaust cleaning

Trial of cleaning diesel exhaust performed at the EagleBurgmann Norway AS laboratories in Norway.


Exhaust buildup that was deposited in an exhaust pipe from an unsuccessful scrubbing system was collected from an offshore site. The solids and particles were diluted back into water to produce a contaminated liquid. The liquid was sprayed directly into the Lynx separator, allowing a concentrated stream of liquid to access our filter directly. The Lynx separator used for the occasion, was the scaled-down Lynx 150 developed for protecting dry gas seals with very low liquid amounts.

The complete article demonstrating the Lynx Separator system separating diesel exhaust and liquids can be found here:

The video alone is found here:

The goal of the test was to visually observe the ability to remove contaminated liquids and particles from a gas stream. The test exceeded expectations, completely separating all particles and liquids, allowing only clean gas to pass through.


We did not expect such a good result from this version of the Lynx.  This version of the Lynx principle was designed to only handle the smallest possible amounts of liquids. Even when liquid is sprayed directly into our rotating mesh, nothing is getting through, showing the reserve capacity that is available to handle both gas and liquid flow variations.

CEO Sondre Jacobsen

The principle is now being developed to handle ships exhaust systems, where it will be scaled up to handle exhaust outlets up to 6 meters in diameter. The Joint Industry Project is open for collaboration, contact Jesus Ernesto Diaz Silva ( for more information.

InnSep collaboration with EagleBurgmann

Rely on excellence

InnSep collaborates with EagleBurgmann to develop the Lynx Separator for protection of Dry Gas Seal systems for compressors. Liquid entrainment causes seal systems to break down and cause compressor failure. Global losses are estimated at several billion dollars in equipment damages and production shutdowns. The Lynx technology reduces this risk significantly, enabling uninterrupted production and less unplanned maintenance costs.

The co-operation was profiled in the Oil and Gas publication MNOG 2-2015: Midt-Norsk Olje og Gass article – Page 25
