Dear Manasi, 
We have measured the temperature for the ATFE concentrate, 
•	ATFE Ia concentrate, 50 deg C at vacuum of 4 mbar. We believer that the actual temperature can be higher, 50~55 C, due to the heat lost at measuring point.  Do we still need the hot water (60) jacket tank and piping, or a heat insulation will do the work?
•	ATFE Ib concentrate, 92 C at vacuum 1mbar, the actual temperature may be 92~95 C. It seems that we can use the open steam as insulation medium with temperature of 100? However, if there is any stagnant material in the receiver, the materials will be overheated after certain hours. Do you have any comment?
•	ATFE II, concentrate, 76.9 C at vacuum 100, the actual temperature may be 76.9 ~80 C. Please advise the insulatinging medium.
