What more were you able to find out about throughput?
i verified it in the time I was there. It's simple pounds in/pounds out. I watched the gas comporession system and the burner to tell me how much heat was being driven into the system. The charge is monitored by a scale and the final petroleum product was quantifiable by the level of the fuel in the tank. What is important here is the ratio of charge to final product. They scale scale the the machine to whatever size they want. So to me 20T was not the important question. The material balance is what is important. They have excess heat so the primary production factor in this machine is how much heat can they drive into it.
The ratios provided by JBI jive with the material and heat balances I was able to complete.
What type of regulatory limit?
They have no emission monitoring or controls so the only way to ensure they do not exceed Title V emissions is to limit the lbs in. They have a long way to go to reach a Title V so I believe a simple per amendment for a 100T or more a day machine would not be difficult to get.
