“Hot Topic” Webinars On Measurement Of Mercury SO3, Ammonia Slip, NOx July 12

 

There are so many developments on Mercury CEMS that we have added an afternoon “Hot Topic Hour” on July 12 to cover the developments.  This is in addition to our long scheduled morning discussion on measurement of SO3, ammonia slip and low level NOx.

 

Three challenges for the CEM supplier industry are measurement of ammonia slip, SO3 and NOx at very low levels.  What continuous SO3 measurement is necessary to control flow of removal additives?  Can NOx analyzers accurately measure the 0.07 lbs/MMBtu or less that represents the limit in many permits?  What are the cost and reliability of CEMS for these applications?  Ammonia slip causes opacity problems and pluggage of air heaters.  Can you accurately measure and therefore control it?

 

At 9:00 a.m. CDT on July 12 there will be a 1-2 hour discussion of these issues.  Then at 1:00 p.m. CDT we will re-convene to discuss the mercury measurement issues.

 

EPA has released "draft" method 30A and 30B which represent the instrumental analyzer and sorbent trap methods for doing RATA.  How comfortable is the industry with these draft methods?

 

Now the NIST certification protocol for mercury calibrators (elemental and oxidized) is being worked on.  Where does this process stand?

 

There are still questions on obtaining accurate measurement with the CEMS systems including probe plugging, sample transport and conversion of oxidized to elemental mercury.  We will hear from the system integrators and instrument suppliers about these issues.

 

We have now conducted several “Hot Topic Hours” on mercury CEMS.  So this one will build upon the others and utilize the extensive information in the McIlvaine Mercury Decision Tree. For more information on these and other “Hot Topic Hours, click on:
