Dear seniors: I am a recent graduate, and my graduation project is titled “Program Control for MTO Olefin Separation, Drying, and Regeneration.” This topic originated from the Shenhua Baotou project. I don’t know where to start working on this project; I need to write a proposal now, but there is very little background information available. In particular, I have no idea what “program control” entails. I hope some of you seniors can provide guidance – I would be extremely grateful! If there is any information that is not subject to confidentiality requirements, please send it to my email address higodan88@126.com. Thank you very much! :'( .Note $ # , $ $
The control of the regenerative system can draw on the approach used in FCC (catalytic cracking) systems for such control. However, as far as I know, the regenerative system is not under program-controlled operation, since it operates continuously, with the catalyst being regenerated while it is also undergoing reactions. Drying is simply controlled by a program; it’s a very easy task. All you need to know is about the two drying tanks – one for regeneration and the other for production. The switching process involves pressure equalization ； The regeneration tank is put into operation, while the regenerator tank is taken out of service ； Depressurize the reactor vessel ； Blowing of the reactor vessel ； Regeneration of the raw material tank ； Cooling, pressurizing, ready for operation. Just use your professional knowledge to create a program for it.
2nd floor; the question on the 1st floor was about the olefin separation unit. The MTO unit referred to generally consists of two process units; one is the MTO unit itself, which has a reaction and regeneration system similar to that of a catalytic cracking unit (FCC), and falls under the category of oil refining ； The other is an olefin separation unit, similar to the binary refrigeration separation system used in ethylene plants, and falls under the category of ethylene. Therefore, the MTO unit at Shenhua Baotou is composed of the DMTO unit from Dalian Institute of Chemical Physics plus Lummus’ olefin separation unit. The project for the first floor can start from the industrial control system aspect of the ethylene plant. Last edited by The wise are enlightened on 2009-3-4 21:47]
