The production rate required is 120 000 ton/annum of methyl acetate. The plant operates for 330 days in a year. 1. Calculate the maximum economic potential (in $/annum) at the given production rate. [4] 2. Draw an input-output structure for the process Provide a justification for the drawing. [8] 3. Perform a material balance for the input-output diagram. State all assumptions and report flowrates in units of kmol/h. (12] 4. Determine the economic potential (in S/annum) of the process.
