Question
1. Process integration definition and one example of the use of process integration 2. What is the influence of the temperature increase and the reduction of pressure in the process on the total cost of the apparatus in which the process is carried out? 3. Heat recovery definition 4. Mark on the diagram: heat recovery (QRec), external heating (QH), external cooling (Qc). 250 Hot composite curve 200 150 Cold composite curve 100 50 1000 2000 3000 4000 5000 6000 7000 H (kW) What do you think: - When heat recovery increases - then does external energy costs increase or decrease? Justify your answer briefly. - When heat recovery increases - then does capital costs increase or decrease? Justify your answer briefly. - Mark on the graph cost = f(heat recovered) the optimal heat recovery. 5. Three main targets for heat recovery systems. 6. How can a process be defined? Characterize batch and continuous processes. 7. Characterize different heating or cooling systems. 8. Characterize ways to transfer energy? 9. Heat transfer characteristics of boiling. 10. Description apparatuses: reboilers and vaporizers. 11. What should be considered in process heat exchanger design? List and describe. 12. Show schematically examples of water reuse and regeneration. 13. Water treatment processes classification. For each of three group give one aim and one example of process. 14. What treatment processes can we use for one of the following contaminants: suspended solids, heavy metals, dispersed oil? Describe shortly one of primary treatment processes. 15. For what purposes can water be used in process operation. 16. How clean chemical reactor technology can be developed, 3 examples? 17. The ways to minimize waste from process operation.
