Based on our yesterday’s (15th Sept.) meeting in your office, kindly confirm the following :-

1)	For Thin film evaporator (TFE) (tag no.V100DS30WV200), it is decided to use SS 316Ti shell instead of SS 304L indicated in the datasheet.  All other material of construction will remain the same as given in the datasheet except the shell which will be in SS 316Ti.
 
2)	Following details are given in TFE datasheet and sketch. 

Shell ID – 600 mm
Jacketed length of the shell – 2496mm as per sketch i.e. 2 sections of 1248 mm each.

Based on these dimensions, the heat transfer area of TFE is coming out to be 5 m2 instead of 6 m2 indicated in the datasheet.  So please confirm the above dimensions.   

Also the jacket O.D. indicated in the sketch is not clear i.e. whether it is 560mm or 660mm.  If the shell ID is 600mm then jacket OD should be 660mm only.  So please re-confirm these dimensions again.

3)	In Falling film evaporator (FFE) (tag no.V100DS30WV100) sketch / drawing (page 5 of 5), section AA of the tube  is not clear.  So please send the details of this section.

Also confirm the make of the spray nozzle which we have to use in this FFE.

4)	We will be using roller chain coupling for the agitator for TFE & Short path evaporator (SPE).  Please confirm the make of the roller chain coupling.
 
5)	We require the inlet & outlet operating temperature for process & utility side of TFE to check the requirement of expansion bellow on the jacket side of TFE.  In the datasheet of TFE, the inlet temperature on the process side (shell side) is given as 197 dg.C. But the outlet temperature is not indicated.  So please confirm the outlet temperature on the shell side.
6) 	Shell ID of TFE is given as 600mm in the datasheet.  But the vapour nozzle size is 24” i.e. 610 mm.  So it is not possible to attach 24” vapour nozzle to the shell of 600mm.  So please confirm the revised vapour nozzle size again if the shell ID is correct.
