SCR Catalyst Retrofitting

SCR Catalyst Retrofitting

Modular Complete MWM Solution

Comply with Emission Limits While Ensuring Plant Efficiency and Availability

Selective Catalytic Reduction (SCR) is an advanced active emissions control technology system that reduces emissions of nitrogen oxides NO_X in a sustainable and long-term manner. It has a direct impact on purity of exhaust gases released into the atmosphere, and accordingly contributes to environmental protection.

The SCR catalyst components

(can be implemented in the form of a containerized solution or in a building):

• SCR catalyst housing
• SCR catalyst and oxidation catalyst honeycomb
• Dosing unit
• Control
• Injection section
• Compressed air unit
• Urea tank

A urea-water solution is injected into the exhaust gas after the gas engine and before the catalyst. The thermolysis and hydrolysis in the exhaust gas produces ammonia (NH₃) and carbon dioxide (CO₂). In the catalyst, the ammonia causes a reduction of NO_X, resulting in nitrogen and water.

Apart from the catalyst, we can offer you the following products and services:

• Urea tank
• Urea solution MWM Premium U 32.5
• Service and maintenance
• Financing from 0% p.a.

Easy retrofitting by MWM Service:

For the retrofitting of existing plants, MWM offers a compact turn-key solution with SCR catalyst, optionally also with urea tank and urea solution. As the retrofitting of existing plants takes very little time, the downtime is very short. Moreover, MWM Service evaluates all the steps that need to be taken in advance in order to ensure a smooth and speedy transition. After the existing peripherals have been disconnected, the new SCR catalyst can be mounted. Additionally, the urea tank is set up, the control system is installed, and the SCR system is linked to and integrated in the existing engine control. Optional remote system access ensures quick support and high system availability.

Benefits of MWM SCR catalyst retrofitting at a glance:

• Modular complete solution in compact design
• Even more efficient plant operation with reduced emissions
• Service and maintenance by qualified personnel
• Comprehensive EPC (engineering, procurement, and construction) retrofit solution including urea tank and urea solution
• State-of-the-art urea injection technology, controlled by the actual NO_X values measured
• Remote access to the system for quick support and high system availability
