Sayoub:
In 2003 I helped one of our Student members from Spain in his formal thesis related to the design of an MTBE process plant. He succeeded in his endeavor at the University of Salamanca - one of the oldest universities in Spain. As an act of gratitude, he sent me his complete work in a formal printed, 150-page bound book as well as in a CD. This work contains all the calculations, sketches, drawings, tables, background, and formal written presentation of all the work effort that went into his product - all subjected to review and detailed questions and inquiries.
This includes the basic flow diagram. The product is in Spanish. If you are interested I can try to send you a copy of the flow diagram used to generate all the subsequent related calculations.
At present I am 100% dedicated as a caregiver to my wife of 62 years who has medical care needs. I have entered the Forums again due to a rare availability of free time while my wife rests, so I have had time to read your thread. Let me know if I can help - but tell us your time schedule or deadlines.
