While were are on the subject of feedstock, we also need to consider the effect that varying the feedstock will have on the combustible gas that is produced by the process.
JB has stated that once a process run has been started up, the gas product will be used to fuel the ongoing process. It is the product of the combustion of this gas that is subject to the stack testing being done pursuant to obtaining the air permit.
Since these gasses are the result of an industrial process, i.e. not simply the result of the combustion of a single known fuel such as natural gas, it is reasonable to suspect that their composition may vary depending on the different feedstocks used in the process.
Here in North Carolina the process data are essential to getting the permit, and the permit may restrict the process to the parameters used in the testing. Is the same is true in NY?
So, I need to know what happens to the results of the stack tests when content of the feedstock is not tightly controlled, and what effect will this variability have on the resulting permit. Any NY permitting experts here?
