The goal: to improve the exhaust gas analysis

Together, the Steinbach-based company “AGT-PSG” and the University of Applied Sciences Rhein-Main have been developing a better treatment of measuring gases from combustion processes since August of this year. The state supports the project with around 240,000 euros.

Much has been discussed in recent years about emissions standards, nitrogen oxide pollution and measurements of pollutant values. At the Steinbacher company “AGT-PSG” one knows that only too well. “Climate protection and the reduction of CO2 emissions are not just a focus topic since the ratification of the Paris Climate Agreement,” says Jörg Erens, Managing Director of the medium-sized company, which employs 42 people at the Steinbach and Erkelenz locations. The company specializes in devices for extractive gas analysis, ie measurements that are not carried out at the point of gas leakage.

“In harsh environmental conditions such as the inside of a chimney, many measurement principles do not work and require gas extraction and external analysis,” explains Prof. Dr. med. Stefan Rusche from the Institute for Sustainable Mobility and Energy (INME) at Rhein-Main University of Applied Sciences, which has been cooperating with the company for about three years.

“AGT-PSG” produces probes for sampling, heated pipes for transport and refrigerators for the processing of the measuring gases. “The gas must have the same condition with the analyzer as with the removal,” says Erens. Of particular importance is the gas treatment. For this purpose, the measuring gas is dried by means of a cooling device for the sensitive analyzers, resulting in condensate. The problem is that water-soluble pollutants would be washed out with the condensate, explains Rusche. “This leads to a faulty measurement of the emission values. 80 percent of the measurement errors occur in the treatment. “In the research project” Zymira – cyclone cooler with reduced leaching of measuring gases “university and companies are working together on a solution.

Simulations on the computer

“The goal is to avoid leaching through the shortest possible contact of condensate and water-soluble, gaseous exhaust gas constituents,” explains Rusche. The project has been running since August. In the first step, the university is in particular required. “We run simulations on the computer that a medium-sized company could not afford. The correct geometrical shape of the cooling unit, its basic materials and the surface configuration must be found. “Once the prototype has been developed, it goes to the practical tests in the company. The end result is a marketable product that finds application in the automotive industry, shipbuilding or in factories and power plants. “Wherever combustion gases are produced,” says Erens. Especially in Asia, he sees a growing market.

Project costs are estimated at around 370,000 euros. The company raises just under 130,000 euros from its own and third-party funds, the remaining amount of 241,802 euros there’s about the “LOEWE funding line 3” from the Hessian Ministry of Science and the Arts. “I am already looking forward to the findings that the researchers will achieve by the end of the 2020 project,” said State Secretary Patrick Burghardt (CDU) when he presented the donation contract. Decisive for the granting of the funding was the innovative nature of the project, explains Frank Syring, chairman of the LOEWE-3 selection committee. . “With” AGT-PSG “the promotion is a privilege. Erens: “As a company, that makes us proud.”
