PFD, stream table, reaction kinetics, and specification of the major equipment of the dimethyl ether production unit are provided in the attached file.
a) Use the skills you acquired (diagrams and conceptual chemical process design) and provide a detailed process description for the DME production process. Review Douglas’s method and provide detailed information about process chemistry, input/output stream structure, recycle structure(s), separation systems, utility, and the possibility of heat integration. You can use calculations in Part “b” for a more detailed and specific description. (limit: 500 words)
b) Use engineering heuristics to size the following major equipment:
– E-201, E-202, E-203, E-204
– P-201 A/B, P-203 A/B
– R-201
– T-201, T-202
– V-201, V-203
Follow (step-by-step) heuristic rules for each piece of equipment and provide sufficient details and reasoning for your calculations. Compare your findings with specifications reported in Table B.1.3.
NOTE: The whole concept of heuristics is to make an engineering-based estimate based on well-accepted rules of thumbs. If any required information for part b is missing, use the stream table, process diagram, and database available (Aspen Properties or a simple Google search – with mentioning the reference) to make a logical estimate.
Hints:
E-201 => The temperature for MPS can be found in the text (Page 215) or from Aspen. To estimate Q, calculate the sensible heat and heat of condensation. Even if your numbers are not close to those from the equipment summary, I want to see your cal
