Anita,

This budget price is based on our data base and was not developed as a line-item estimate.

Sorry,

One additional question - is it possible for me to see the line-item break out of the SCR system cost?
Thank you so much for all of your time - I really appreciate it.

hi Tony,

Thanks so much for this information. Just to make sure I understand completely - the 0.5% SO2 

conversion guarantee represents the total conversion over all layers of catalyst , not just a single layer, 

right? YES And this SCR system would use 3 layers (or 4?) of catalyst? IT IS A 3 PLUS 1 FOR 

FUTURE, AFTER THE INITAIL 16000HRS ANOTHER LAYER WOULD BE ADDED WITH 

AN ADDITIONAL .2 SO2 CONVERSION.

NO

What would determine whether 80% or 90% NOx reduction is achieved? FUEL CONSTIUENTS AND 

VOLUME OF CATALYST Is it a function of ash or other components of the flue gas? YES Or level of 

acceptable ammonia slip (2%?) or how often the catalyst is changed out? TYPICALLY EVERY 2 YEARS

Load levels? NO

And the SCR system cost estimate of $100 to $200/kW is the purchased equipment cost and does not 

include installation costs? THIS IS ENGINEERING, MATERIAL AND ERECTION What equipment is 

included in that cost estimate? BASE SCR SCOPE WITHOUT FANS OR HEAVY ELECTRICAL 

MODIFICATIONS

How frequently is it recommended that catalysts are changed out? TYPICALLY EVERY 2 YEARS Is there 

a cost associated with catalyst disposal PLATE CATALYST CAN BE RECYCLED FOR THE METALS OR 

REGENERATED or can catalyst be regenerated? Does this assume urea or ammonia injection? NH3

Thanks so much for your help!

RE: CX catalyst question

 

Anita,

We have reviewed your request and have the following response:

Catalyst development has progressed over the last few years to the point that an initial SO2 conversion 

rate of 0.5% can be guaranteed with 80 to 90% Nox reduction. Sub bituminous western fuels have similar

chlorine levels to PRB fuels and as such would have low or no Mercury oxidation from standard catalyst. 

Should Mercury oxidation from the catalyst be a benefit, then a feasibility review for TRAC catalyst would 

be required. With the limited information available, that review was not possible. Under typical boiler 

operating parameters, Mercury oxidation could be guaranteed with a range from 60 to plus 80%. 

The SCR System cost would range from $100/Kw to $200Kw. This was based on a unit size from 750 to 

250MW. The impact on TRAC on the total system cost would be marginal. 

Should you have any questions, please advise,

Anthony C. Favale P.E.

Anita,

I received your voicemail but I was unable to call you back.

The pricing I gave you is conservative based on today’s catalyst price. I do not know how far into the future 

you need a price for but this number should hold for a while. Today’s price is about $5500 for CX and 

about $6000 for TRAC. 

This pricing is not confidential.
