SKThe Cleaning of Industrial Flue Gases
Let’s contribute toward a better future. Let’s reduce the concentration of emissions in waste gases in an environmentally friendly and safe way.
ROPA Group is ready and able to help you design solutions, deliver effective technologies that reduce NOx and SO2 emissions, and to optimize the installation and servicing of your existing technology. Our team of experienced engineers will provide legislative advice and prepare studies. They are also highly competent in supervising projects and getting them implemented.
Denitrification
Selective non-catalytic reduction (SNCR) and selective catalytic reduction (SCR) are methods for reducing nitrogen oxide emissions from waste gas that are both efficient and environmentally friendly. These technological concepts provide high reliability with minimum maintenance requirements.
These technologies for reducing nitrogen emissions in waste gases are designed for use by stationary sources burning solid, liquid and gaseous fuels. When using SNCR and SCR simultaneously, ROPA can supply the full range of reagents and services, including optimization of the plant and equipment that operate with these nitrogen reduction methods.
Desulphurization
Reducing the emission concentrations of acidic components in waste gases through desulphurisation represents an advanced ecological method. This process operates on the principle of injecting dry sodium and calcium-based powder sorbents, thus allowing to minimize water consumption in industry.
Technologies, designed and supplied by us, help eliminate acidic components, especially SO2, HCL and HF. When designing, we focus on the specific process conditions that are essential for optimal efficiency in reducing acidic components in waste gases. This method is not only environmentally friendly, but above all it represents the most cost-effective solution.
SCR Technology
NOx emissions are lowered by the injection of a reducing agent upstream of the SCR catalyst during the gaseous or liquid phase. Although SCR demands more investment in technology compared to other NOx abatement methods, it will reduce NOx emissions by more than 90%, depending on the type of combustion plant and the conditions under which it operates.
ROPA Group works with reputable catalyst manufacturers to design SCR devices and equipment.
During the initial phrase, the project will be evaluated in a feasibility study that can aid you in deciding whether to go forward with it. As a general contractor, ROPA will provide you with complete delivery of turnkey technology, including all drawings and the design. You can also rent GREENOX technological solutions over the long term if you are interested in deploying them.
A full range of reagents and services for current SNCR and SCR technologies can be supplied by ROPA, including the optimization of plant and equipment that operate on them.
SNCR Technology
Here an injection of a liquid reagent into the combustion chamber reduces NOx emissions. SNCR demands much less investment into technology than other NOx emission reduction methods and can reduce NOx emissions up to 65%, depending on the type of combustion plant and the conditions under which it operates. The technological concept is characteristically simple and highly reliable with minimum maintenance requirements.
Medium and large combustion plants would have ROPA Group built and customized devices that are fitted to take the specific process and operating conditions into account. Our own compact GREENOX solutions are available for deployment in smaller combustion plants.
