Optimum number of effects in a multiple effect evaporator is decided by the____________________?
Correct answer: A. Cost benefit analysis
- A. Cost benefit analysis
- B. Floor area availability
- C. Terminal parameters
- D. Evaporation capacity required
Explanation
Adding effects saves steam but increases equipment and operating complexity, so the optimum is found by comparing the economic benefit with the added cost. This is a cost-benefit decision rather than a choice based only on floor area or capacity.
