Seeking help with question 44 from the professional exam on the afternoon of the first day in 2010
Thread Content
Which of the following statements are incorrect? A. For the separation of systems with large load variations, a floating valve tower B is advisable. For the separation of corrosive streams, a plate tower C is recommended. For the separation of substances containing solids, a packed tower D is recommended. For the separation of foamy systems, a packed tower is advisable. I think the answer is ABC, because it is stated in the Tianjin University version that when the load variations are large, a plate tower is advisable. But many of the correct answers are BC. I’m confused; could you please tell me whether A is right or wrong? I would be very grateful if fellow sailors could help answer this question.
Hello: OP. As you said: since the load variation is large according to the Tianjin University version, a plate tower is preferable; the answers are BC. That’s correct, please check your meaning again!
Thank you to the person above; does a floating valve tower belong to the category of plate towers?
Float valve trays have high production capacity and can handle heavy loads； But it’s not the load that changes greatly! Please be sure to pay attention!
Look at page P549 of the association’s textbook; choosing BC is the right choice
Float valve towers have a high degree of operational flexibility; it means that the load can vary significantly. You have misunderstood this
The floating valve tower is also a type of plate tower
In BC questions, one has to select the incorrect option! Float valve towers have a high degree of operational flexibility and can handle large variations in load – there was a misunderstanding regarding this point earlier; for separating corrosive substances, packed towers are more suitable; for separating substances containing solids, plate towers are preferable; when it comes to separating foamy substances, packed towers may cause the foam to break up, so packed towers are not the best choice in such cases.
