Design of a new technology for crude caprolactam refining

Partner: SPOLANA s.r.o.

SPOLANA, s.r.o. is the sole manufacturer of caprolactam in the Czech Republic, which serves as a key monomer for the production of polyamide 6 with wide applications in the textile, construction, and composite industries, while its global consumption is growing. In cooperation with TECHEM CZ, s.r.o. and the CEET-IET research center, an innovative caprolactam refining process was developed, replacing the carcinogenic trichloroethylene regulated by REACH legislation and allowing for the same or higher product quality. This included the establishment of laboratory facilities and planned verification on a pilot unit; this development supports the company's strategy of modernization, safety, and environmental protection, while bringing economic savings and improving the company's public perception.

Partner’s Note

"We would like to highlight our long-term and successful cooperation with CEET-IET at VŠB-TUO. During our aforementioned joint projects, we had the opportunity to experience their professional approach, high level of technology, and deep knowledge of the field. CEET-IET has proven to be a leading scientific workplace focusing on innovative and sustainable technologies for environmental protection. Their team of experts is not only well-trained but also constantly monitors and applies the latest research and trends in the field, which were continuously implemented during our cooperation on joint projects, both within the ELTRIS project and the KONTIRAK project. During our collaboration, we focused on applied research in the field of caprolactam refining. Thanks to their expertise and technological know-how, we were able to successfully fulfill the substantive scope of the projects and achieve excellent results. Their approach to solving this issue was innovative and effective, allowing us to make significant progress in caprolactam refining. Overall, we can say that the cooperation with CEET-IET has been very beneficial and inspiring for us."

Increasing the efficiency of nitrogen oxide reduction technology

Partner: SMS CZ spol. s r.o.

The project focuses on the energy utilization of non-recyclable and hazardous waste that cannot be recycled or landfilled, where the thermal decomposition process removes its hazardous properties, reduces its volume, and simultaneously produces energy in the form of heat or electricity. In collaboration with SMS CZ, CEET-IET developed modern technologies for reducing emissions and replacing fossil fuels with waste-based fuels. This includes a mobile containerized unit that enables the energy processing of waste directly in locations without infrastructure or after natural disasters, thus bringing ecological and energetic benefits with practical application in various industrial and crisis conditions.

Partner’s Note

"We have been cooperating with CEET laboratories since 2013. We were very pleased that the newly emerging laboratories of the institute chose our company as the supplier of technology for energy recovery from waste. From the very beginning of our mutual contact, I sensed that the cooperation would be long-term.

Over the course of ten years, we have jointly and successfully resolved five research projects, and we have plans for new ones. The results of our mutual cooperation have helped us in our business activities. We have gained new knowledge that we capitalize on in our production, making our newly offered products more competitive and, above all, more environmentally friendly. At the same time, we must proudly mention that our joint results have gained recognition among the professional public."

New technology for waste gas treatment using advanced oxidation processes

Partner: DEKONTA a.s.

Commonly used technologies for the removal of undesirable substances from waste gases include adsorption, catalytic combustion, or biofiltration; however, these often exhibit a number of disadvantages. Therefore, advanced oxidation processes, especially photochemical oxidation, are emerging as a promising alternative, being effective even at low concentrations of toxic or odorous substances while also being advantageous in terms of operation and costs. The collaboration between CEET-IET and DEKONTA led to the development and testing of a pilot-scale photochemical unit in various industrial operations, thereby bringing significant progress in the field of waste gas treatment and environmental protection, while also creating a foundation for other similar applications.

Partner’s Note

"I would like to commend the excellent cooperation with CEET-IET in the field of waste gas treatment using advanced oxidation processes. This collaboration represents a prime example of a synergistic partnership between a scientific institute and an industrial entity aimed at protecting the environment and ensuring sustainable development. I want to express my appreciation to both parties for their effort, expertise, and commitment. Our collaboration is practical proof that science and industry can work together to solve key environmental challenges. I believe that the cooperation will continue and contribute to further innovations and the improvement of the environment, not only in our country but also globally."
