Industrial exhaust gas purification is a vast area. There are many different technologies and facilities for the effective treatment of pollutant emissions. This is primarily due to the high heterogeneity of exhaust gases from different industrial processes. PES delves deeper.
Depending on the application, the composition of the exhaust gas can vary greatly from process stage to process stage. The modular system allows individual adaptation to the specific process application.
This poses a challenge for conventional systems for exhaust gas purification, as individual exhaust gas purification technologies are often pushed to their limits for variable gas compositions. centrotherm clean solutions GmbH & Co. KG has therefore developed a modular system for cleaning exhaust gas.
The modular system combines different cleaning technologies put together depending on requirements. Cleaning systems for thermal or wet-chemical treatment as well as dry bed absorbers can be combined with each other according to customer specifications. At the same time, intelligent communication of the system modules guarantees safe and cost-optimised operation at all times.
‘In order to find the best possible exhaust gas purification solution for an industrial application, the various factors of an application must be carefully considered,’ explains Thomas Kraus, Sales Manager Europe at centrotherm clean solutions GmbH & Co. KG. ‘In addition to environmental protection and minimisation of health risks for employees, operational and maintenance costs, running costs and the flexibility of the process to adapt to different process conditions also play a central role.’
While the various options for exhaust gas cleaning, such as exhaust gas combustion, the removal of pollutants using a dry bed absorber or wet scrubbing, have been established on the market as individual systems for some time, combinations have so far not gained much acceptance. The reasons for this include the high complexity of such complete systems and the fact that most suppliers specialise in one technology.
Modular design for the best possible exhaust gas cleaning
centrotherm clean solutions’ product portfolio covers the purification of exhaust gases in a variety of industrial applications using various technologies. When designing a system, consideration of customer-specific system requirements plays a central role.
These include in particular the existing building installations at the site, the specific process application, as well as any local environmental regulations for industrial companies. Based on these basic conditions, different technologies or individual modules can be combined individually in a modular system to form a complete system for the respective application.
The combination system assembled in this way is has a central control system with touch screen on which the entire system function is fully visualised. Connection to a central control room is also possible. In this way, all important system parameters can be conveniently monitored and controlled.
By closely coupling the signalling with the production plant, the exhaust gas purification system automatically regulates the necessary output for disposal, as well as selection of the module that is suitable for the respective process step. ‘As the solution is not an out-of-the-box product but always custom tailored, we can be flexible in adapting the system to the requirements on site,’ says Kraus.
