FW: 0031 sampling for Coke Oven ICR


Eric,

Stef forwarded me your email.


The 2 hour sampling time in the method is assuming a constant process and . Since this process is intermittent, and you may disregard the total sampling time requirement.

Hopefully, this will alleviate your concern with leaving the train assembled and covered overnight.

Please let me know if you have any additional questions.

Stef,

I have a question for you on the Coke Oven ICR and I'm hoping you can point me in the right direction for some clarification.

We are going to be testing on a pushing process next week that pushes for roughly 2 minutes, then is down for around 10 minutes. For a 12 hour shift I believe they are getting about 48 pushes. We are running into difficulty trying to figure out how to sample the 0031 train and collect a good, representative sample within the confines of the method (20 minutes of sample/set of traps, 120 minutes of sample time, etc.) 

Do you know if there is or was any discussion about alternative sample procedures for this ICR? Doing one set of samples a day for the 48 pushes is going to be reasonable for us, but I don't think we can get the 120 minutes of sample, which means we then leave the train assembled and covered overnight, which doesn't bode well for our data on the back end I wouldn't think.

Please let me know your thoughts and feel free to pass us on to whoever might help, also feel free to give me a call on my cell at 630-699-7690 to discuss.

Thanks,
Eric
