Which of the following ratios defines the recycle ratio in a chemical process ?
Correct answer: B. Recycle stream/fresh feed stream
- A. Gross feed stream/recycle feed stream
- B. Recycle stream/fresh feed stream
- C. Recycle stream/gross feed stream
- D. None of these
Explanation
The recycle ratio compares the stream returned to the process with the fresh feed entering it, commonly written as recycle flow divided by fresh-feed flow. Gross feed includes recycle, so it is not the usual denominator for this definition.
