Acetic acid (HAc) is generated by the addition of 10% excess sulfuric acid to calcium acetate (Ca(Ac)2) (stream 1 compared to stream 3). The flow diagram is shown below.
The reaction Ca(Ac)2 +H2SO4 -> CaSO4 + 2HAc goes to 90% conversion based on a single pass through the reactor. The outlet stream from the reactor is separated into 3 streams, one containing Ca(Ac)2 which is recycled, one containing HAc, and one containing H2SO4 and CaSO4.
Find the amount of recycle per hour based on 1000kg of Ca(Ac)2 feed (stream 2) per hour. Also calculate the kg of HAc manufactured per hour.
