NOx reduction with SCR (selective catalytic reduction) bypass system from SICK | SICK AG

Product information: www.sick.com/gr...
Efficient flue gas cleaning is used in modern power stations. A secondary method used to reduce NOx is the SCR (selective catalytic reduction) that uses NH3 for conversion of NOx to nitrogen and water. Even with high dust concentrations, high temperatures, and high gas velocities, control and efficient operation of the SCR system is ideally done in-situ, in real-time, and across the full diameter of the process duct. Our solution: the SCR Bypass System from SICK.

The insensitivity to dust mentioned is in regard to the measurement, not the catalyst. Also, a too high temperature will burn ammonia on the cat and produce more NOx.
The measurement system though is ingenious, cooled and purged. Great.

HI, Can I ask a question?
Where is NH3 injected into the system?

[@SICKSensors]

Typically the catalyst used in the SCR is vanadium or tungsten.

[@rizwanshaikh5472]

NH3 is usually injected from where the exhaust gas enters the system.

Thank you so much sir good video..
I need your help,
I m facing problem with sick MG32,
There showing Failure and Maintenance required and I have disturbed the Alignment too..

[@SICKSensors]

Can I ask how many years a SCR can last usually?

[@SICKSensors]

The SCR system is not manufactured by SICK. An average investment period for an SCR is 10 years. Our product is the in-situ gas analyzer GM32. This is the bypass that measures NOx and is used in combination with our products GM700 (measures NH3) and FLOWSIC100 (measures flow) to achieve optimal control of the SCR process. With good maintenance, our system will run at least as long as the whole SCR system.

@@SICKSensors Thank you so much...A SCR 's average longevity is only 10 years. Now I understand

[@SICKSensors]

You are welcome!

[@kalpeshwani8520]

How much is the time delay to adjust the ammonia slip..

[@SICKSensors]

For the NOx measurement the response time is approx. 9 seconds.

You're SICK!

[@shubhamgupta-tg6id]

which catalyst is used as scr catalyst?

[@SICKSensors]

Hi, the SCR uses NH3 for conversion of NOx. I hope this answers your question.

Hello sir.Are you interested in Scr catalyst?
