In the operation of a synthetic ammonia plant, a 1:3 nitrogen-hydrogen mixture is fed to the converter resulting in a 37% conversion to ammonia. The ammonia formed is separated by condensation, and the unconverted gases are recycled to the reactor. The initial nitrogen-hydrogen mixture contains 0.3part of argon to 100 parts of N2-H2 mixture. The toleration limit of argon entering the reactor is assumed to be 7 parts to 100 parts of N2 and H2 by volume. Estimate the fraction of recycle that must be continually purged.

Question
In the operation of a synthetic ammonia plant, a 1:3 nitrogen-hydrogen mixture is fed to the converter
resulting in a 37% conversion to ammonia. The ammonia formed is separated by condensation, and the
unconverted gases are recycled to the reactor. The initial nitrogen-hydrogen mixture contains 0.3part of
argon to 100 parts of N2-H2 mixture. The toleration limit of argon entering the reactor is assumed to be 7
parts to 100 parts of N2 and H2 by volume. Estimate the fraction of recycle that must be continually purged.
