A feed stream containing pure species L flows into a reactor, where L is partly converted to M as shown in the figure. Recycle Stream treamFeedStream/LReactorProductS/(L+)

M

The mass flow rate of the recycle stream is 20 % of that of the product steam. The overall conversion of L (based on mass units) in the process is 30 % . Assuming steady state operation, the-pass conversion of L (based on mass units) through the reactor is

Options

A.
34.2 %
B.
30 %
C.
26.3 %
D.
23.8 %

Answer

Solution

Recycle Steam Feed1LRe→acMtor2/(L3PLro+duMc) t Given : recycle stream is 20 % over all conversion of L =30% on over all loop single pass conversion - (AmountofLatpoint(1)−Lat(2))/Latpoint(1) Point (3) work at a splitter so composition are same

.

0.7 unrecycled steam of L

R = 0.2 /times 0.7F = 0.14F

At point (1) F+R= Mixed feed

.

Product contain L=0.7F So, point (2)

⇒0.7F+0.14F = /frac{0.84F(−b /pm b^2-4ac)}{2a}

Single pass conversion

.

0.2631 = 26.31/\%

Hence, the correct option is (C).
