In view of increasing legal and industrial requirements, the development of efficient exhaust gas purification technologies is very important. The need for innovative solutions for the separation of very fine particles is increasing, particularly in technical processes.
A research team from the Institute of Mechanical Process Engineering at the University of Stuttgart has now developed a new filter technology: the ‘MiniMax’ aerosol separator.
The Technology Licence Bureau (TLB) is supporting the scientists and the University of Stuttgart in patenting and marketing this promising innovation.
Stricter emission limits have significantly reduced particulate pollution in the air. However, given increasing legal and industrial requirements, the development of efficient exhaust gas purification technologies remains urgent. In technical processes, in particular, there is a growing need for innovative solutions for the separation of very fine particles.
A research team from the Institute of Mechanical Process Engineering at the University of Stuttgart has developed a new filter technology: The ‘MiniMax’ aerosol separator combines cyclone components with micro-separators, significantly increasing the separation efficiency. Prof Carsten Mehring and Gunnar Dwars developed a novel combination of swirl separation and the micro-impaction principle. By adding a specially developed guiding device, the invention sets new standards in filter technology.
Outstanding performance at lower costs
The ‘MiniMax’ reduces the separation particle size d50 by around 40 % compared to high-performance axial cyclones, offering outstanding separation performance. At the same time, the innovation significantly reduces operating costs: the pressure loss is 50 % lower than with conventional axial cyclones. This leads to lower energy costs and reduces the load on the systems.
Effective separation of oil aerosols in screw compressors
In most applications, screw compressors with oil-lubricated screw elements are used. These systems release extremely fine oil aerosols, which must be separated according to product requirements or health regulations. The ‘MiniMax’ technology offers a more cost-effective, ecological, and efficient solution than currently available separator elements. It also reduces the required construction volume compared to commercially available aerosol separators of comparable performance.
Ecological advantage through longer service life and less waste
A major disadvantage of current high-performance air/oil separator elements is their limited service life, which results in frequent maintenance and considerable waste. This is ecologically problematic, as the high demand requires continuous consumption and the contaminated components must be disposed of at great expense. The ‘MiniMax technology significantly extends the service life and reduces the need to replace and dispose of such elements, contributing to a more environmentally friendly waste balance.
Wide range of applications in various industries
In addition to its use in compressor systems, ‘MiniMax’ technology offers potential in other areas with similar operating conditions. These include the vacuum pump market, air conditioning, ventilation systems, and exhaust and crankcase ventilation. In all these areas, ‘MiniMax’ technology could offer significant added value through efficient aerosol separation and reduced energy consumption.
Patented technology
A patent application has been filed for the invention under the number DE 102024113463.1. The Technology Licence Bureau (TLB) is supporting the scientists and the University of Stuttgart in patenting and marketing this promising innovation.
