A pharmaceutical product, P, is made in a batch reactor. The reactor effluent goes through a purifiation process to yield a final product stream and a waste stream. The initial charge (feed) to the reactor and the final product are each weighed, and the reactor effluent, final product, and waste stream are each analyzed for P. The analyzer calibration is a series of meter readings, R. corresponding to known mass fractions of P, ,vP.
Xp | 0.08 | 0.16 | 0.25 | 0.45 |
R | 105 | 160 | 245 | 360 |
- Plot the analyzer calibration data on logarithmic axes and determine an expression for xp(R).
Batch #: 23601 Date: 10/4 Mass charged to reactor: 2253 kg Mass of purified product: 1239 kg Reactor effluent analysis: R = 388 Final product analysis: R = 583 Waste stream analysis: R = 140
Calculate the mass fractions of P in all three streams. Then calculate the percentage yield of the purification process,
