Sometimes, in chemical processes, a part of the outlet stream is rejected as waste in order to keep the impurity level in the system within limits. This phenomenon is termed as the_________________?
Correct answer: B. Purging
- A. Recycling
- B. Purging
- C. Bypassing
- D. Recirculation
Explanation
Purging removes a portion of an outlet or recycle stream to prevent inert impurities from accumulating in the process. Recycling returns material to the process, whereas bypassing diverts flow around a unit.
