Presentation Transcript
If Valve trays cost more than sieve trays, why are they often advertised as a way of decreasing tower costs?
What is the effect of increasing the feed temperature if a. L/D is constant b. L/D = 1.15 (L/D)min Note that (L/D)min will change.
Working capital is the money required to day-to-day operation of the plant, and interest on working capital is an operating expense. a. If the feed rate drops, is the working capital cost per kilogram constant? b. What happens to working capital if customers are slow paying their bills? c. Come companies give a 5% discount for immediate payment. Explain why this might or might not be a good idea.
Why is the cost of packing per volume and the cost per tray less when more packing more trays are used?
Use a McCabe-Thiele Diagram to explain how reducing the product concentration allows the use of a lower L/D for an existing column.
