1. - The equipment listed above and shown in the PFD represent typical arrangement of MVR evaporation. Vendor may suggest changes

2. - the liquid to be evaporated is supernatant, whose main components are water and glucose.

3. - evaporation shall be based on mechanical vapor recompression. Steam consumption shall be minimized.

4. - vendor may suggest additional pre-heater if considered necessary or beneficial, for example for start-up.

5. - feed pump of evaporation (0120-PA-0002) pumps from an atmospheric storage tank

6. - evaporation system shall be cleaned using CIP-system

7. - estimated heat exchange areas include 10% margin. Estimated heat duties are for 100 % normal flow.

8. - pressures given in the stream table are pressures at the evaporator or other equipment excluding pumps, except pressures of liquid outlet streams over battery limit that are after pump.

9. - liquid outlet streams shall have 3 bar(g) pressure at battery limit (at grade).

10. - given fouling factor are rough estimates for process stream and should be verified by vendor. Fouling factors have not been given for utility streams.

11. - evaporating component is water, fouling factors used should be based on vendors experience and knowledge.

12. - supernantant has some foaming tendency. Adequate precautions should be taken into consideration in the evaporator design.

9. - given fouling factor are rough estimates for process stream and should be considered as minimum and same should be verified by vendor.

Fouling factors have not been given for utility streams.

10. - evaporating component is water, fouling factors used should be based on vendors experience and knowledge. For 0150-JE-0004, condensing media streams, 2118/2115 streams, fouling factor of 0.0002 m2-

degC/W should be considered as minimum by vendor.
