ENDLESS POSSIBILITIES

As part of our research on various applications that might benefit from our solution, we have identified a few problem areas where we believe NextSeal can form part of the solution

Carbon dioxide refrigeration systems

We are happy to see European supermarket chains leading the way for greener technologies. Using carbon dioxide as a refrigerant is a sustainable solution for keeping groceries fresh. Carbon dioxide, ironically, has a carbon footprint thousands of times lower than traditional refrigerants such as R404a.

But, the high working pressures of carbon dioxide also challenges the refrigeration system designers. These are pressure levels NextSeal handles with ease. More importantly however, with NextSeal it is possible to remove the oil normally needed to lubricate the compressor. This means significantly improved efficiency, reduced design complexity and no need for oil separators or oil management systems.

Natural gas compressor leakage

If America is to meet President Obama’s goal for methane emission reductions (90 million metric tons in five years), technological and operational improvements are needed everywhere possible.

Utilizing the NextSeal technology is one measure that would be part of the solution to meet these goals – but it is a technology a quick return on investment. NextSeal can be integrated in both reciprocating and centrifugal compressors in the natural gas transmission and processing stages.

Calculations show us that leakage can be reduced by more than 90 percent with fewer system shutdowns for seal system maintenance.

Marine propulsion

The industry of marine propulsion is facing the challenges of reducing fuel consumption, carbon dioxide emissions, and gaseous & particulate emissions.

The sealing system causes great amounts of mechanical friction in a Diesel engine. The integration of NextSeal could reduce friction and allow for higher combustion chamber temperatures.

Waste heat recovery

Industries and vehicles let large amount of energy out into the atmosphere in the form of heat from combustion or processing. This heat can many times be used to produce electricity or other forms of energy to use in secondary functions within the vehicle or industry.

The NextSeal technology aims to make waste heat recovery systems more efficient using positive displacement expander technology instead of popularly used turbine technologies. With NextSeal, the systems can be made much smaller than current alternatives making carbon dioxide (having high energy density) a viable refrigerant alternative. NextSeal is particularly suited for high grade heat applications for which the seal have earlier been an issue.
