Hi Michel,
Attached is the reactor temperature profile in Taixing.
Unfortunately in Taixing, only data on reaction temperature is captured.
As for Yichun, they are asking the PLC vendor to see if we can retrieve the data. I hope it Is in time for your visit.
Yuanda does not have a historian (PIMS) currently.
As for your concern on plant internal logistics, from the reaction temperature profile, we can see that the batches are evenly distributed. The gap is due to one reactor being down. See below.
We can discuss more over the phone tomorrow. You can call me under the number below. If you give me a number to call, I can also call you.
