High Temperature Scrapped Surface Heat Exchanger
High Temperature Scrapped Surface Heat Exchanger
(OP)
Greetings,
In the middle of a front end design for a high temperature (230-250 C) process (CSTR) that involves reacting fatty acids. Need to transfer lots of heat as the reaction is endothermic. The mixture is also viscous so considering using a pump around with a scrapped surface heat exchanger to enhance heat transfer. The only experience I have with these heat exchangers has been with low temperature applications. Does anyone have any experience with and/or vendor recommendations for high temperature (270-300 C design) units? I have looked around to some extent but was hoping to get some helpful information ahead of time.
Thanks in advance,
JoeChem

At time we operated a pilot process using both single and twin screw extruders. The link is the one to give you information and not the one we used. there is also a single screw reactor that I can't recall the name.
Make sure you run some corrosion test to determine you MOC. Work I've done with fatty acids at high temperature MOC was a big concern.
