Question

Acetic acid can be produced through the given balanced reaction and with the process shown in the image. In the process, 535 lb/h of fresh Ca(C, H,O,), and enough H,

SO, to be in 10.0% excess for converting the fresh Ca(C, H,O,), is fed into the reactor. The single pass conversion of Ca(C, H, O,, in the reactor is 90.0%. Determine the amount of Ca(C,H,O,), recycled and the production rate of C, H, 0, by performing the given steps. What is an expression for the amount of Ca(C, H,0,2entering the reactor, m3, in terms of the recycled flow ofCa(C,H,O,),, mg, and the fresh feed of Ca(C, H,O,,, m2? What is an expression for the amount of unreacted Ca(C, H,O,), leaving the reactor, m4, in terms of the amount of Ca(C,H,O,), in the recycle stream, mg? What is an expression for the amount of unreacted Ca(C,H,O,), leaving the reactor, m4, in terms of m3? Substitute the first two expressions into the last expression to eliminate the m4 and m3 terms. Plug in known values and solve for the amount of Ca(C2 H3 02)2 in the recycle stream,mg. To find the production rate of C2, H4,O2,, first calculate the flow rate of fresh Ca(C2, H3,O2,), in lb-mol/h. For every pound-mole (lb-mol) of fresh Ca(C,H,O,, that enters the process, how many pound-moles of C,H,O, leavet he process? What is the flow rate of C, H 0, in the product streamin lb-mol/h? What is the flow rate of C,H,O, in the product stream inpounds per hour (lb/h)?
