Selective Catalytic Technology - SCR How it Works

[@Morning1549]

Hello stelzer, its a nice piece of presentation on catalytic filters for NOx

[@flynnt77]

it's odd, but I built and worked around a combined cycle combustion plant. It didn't have a giant plume of smoke coming out of it like that one you show in the picture. The only visible discharge it had it gave wad Steam from the cooling towers. Granted, the first time we fired up the combustion turbine, it did make quite a bit of smoke as a preservative oils were burned off, but that was the extent of it. the plant was completed in 2010, and there was no requirement for any sort of selective catalytic reduction.

I've been tasked with designing my own SCR reactor as part of my Third Year Chemical Engineering Design Project where I'm working in a team to design and entire methanol production plant based in New Zealand. Would be greatly appreciated if I were able to contact you and discuss certain elements in greater detail at a later date. Many thanks for the helpful introduction into the technology and highlighting the potential for automated systems engineering.

Good video David and Bob!

Thanks gents , relevant presentation !

Insulation blankets for the converter are available from AB Technology (abthermal.com) - improves efficiency

Great explaining. Thanks!!!!!!!!!

DIFFERENCE OF SCR SYSTEM USED IN NITRIC ACID PLANT FOR NOX REMOVAL AND SCR SYSEM USED IN DIESEL ENGINE TRUCK

[@mohanraut3232]

Dear Sir, Can we use catalytic conversation for following flue gas a) Carbon monoxide b) Nitrogen oxide c) Sulphur oxide d) Hydrogen chloride gas e) Hydrogen fluoride f) Mercury Vapour,

[@sagarjiyani3506]

SIR CAN WE USE CAUSTIC LIKE NAOH FOR NOX REDUCTION?

[@vevasam]

Thank you so much for such a nice video.

[@salman4430]

why is the size ratio of your device varies? I think there is one problem, it creates a lot of back pressure

[@perlitocabauatan9285]

Q: If my opacity is 1%, what is my nox emissions?

[@flynnt77]

One Thing Remains unclear to me however. what exactly is the Catalyst in the reaction? Is the urea used in the DEF the actual catalyst, or is it the metal in the chamber?

[@flynnt77]

and why does my Samsung phone insist on capitalizing random words when I use speech-to-text?

[@josephhill2868]

I apologise for the late response, however, in light of the question, V2O5, TiO2, Wo3 and MoO3 are typically employed. It would be of great benefit if you ever discovered the answer to your question and further information related to SCRs and still have the files. Kind regards.

[@Psevdokranos]

well explained. Thank you (2020).

[@sumeetshinde4067]

you explained very well I will definitely contact you sir

[@simenyasikhulu]

Well explained. Thanks.

[@shubhamgupta-tg6id]

sir can we use scr system in petrol engines??

[@salman4430]

petrol engine produces less Nox than the diesel engine.

Thank you!
