Please refer to my telephonic discussions yesterday evening with Mr.Nimbalkar . Please review your design for receiving solvent from distillation system and transfer of same to outside solvent storage tank. It should be possible to do it without use of costly pumps. You are to just collect solvent in a receiver where vacuum gets automatically broken without need to introduce either air or nitrogen .The system is part of every solvent plant.

We shall examine PID-E nd come with more comments after hearing from you on above feed back
