A chemical reactor gives a fractional conversion of only 10% of the expensive limiting reactant in the feed stream. Assuming not

hing will improve the reactor’s performance, how would you design a process to make better use of the expensive reactant? What performance characteristics would you need for other process units? (b) A second reactor is available which gives 90% conversion but allows an irreversible, undesirable side reaction with only a 50% selectivity or the desired product versus the undesired product. For some cases, the 1st reactor would be better, while for others the 2nd reactor is a better choice. Explain what performance characteristics of other units would dictate this choice?

Answer:

Explanation:

A) install a SEPARATION unit on the output from the reactor and feed the unreacted reagents back to the reactor feed in a RECYCLE stream.

B) Even if one had a perfect separation unit, the 65% or reactant which went to undesirable side reaction is wasted. Recycle is not effective to help poor selectivity of the reactor.

Whitepunk [10]

Investors at Penny's candies have low expectations from the company since it has a very low P/E ratio. Either the company is not performing well or investors have discounted some bad news in future cash flows.

Whereas Donna's confections has a P/E of 6.7 which is much better than that of Penny's. So here the company is performing well and investors are positive on future good news and they expect the cash flows to improve and hence the stock rules at a higher P/E ratio

amm1812

Answer:

b) False

Explanation:

One of the key features of a good internal control system is the segregation of duties (SoD).

The principle of the segregation of duties entails that an individual is not allowed to initiate a transaction, review and approve the same transaction. In other words, a good internal control system would not allow an individual carry out all processes for a transaction from initiation, to authorization to approval to recording.

A system in which these responsibilities are shared mitigates against the risk of fraud and error.

Hence, in a good system of internal control, the person who initiates a transaction should be NOT be allowed to effectively control the processing of the transaction through its final inclusion in the accounting records
