Hello

 

I am using 4 stage steam ejector to attain vacuum. by proceeding stagewise my reactor achieves 746 mm hg vacuum,but this vaccum drops to 740mm at end of distillation? can any one suggest to attain stable 746 mm at end of distillation?

 

I am Graphite block steam ejector and shut off vacuum of ejector is 750mm, how can i improve the vacuum in ejector  ???

[bmsharad]

Likely some decomposition taking place in the still due to high temperature & increased residence time and the gasses produced adding to the load to the ejector
