The problem of dibutadiene one-pot polymerization ACN

Thread Content

Have there been any issues with rising tower pressure in the one-extraction system of acetonitrile-based butadiene extraction units?
Reply #22016-05-09
High tower pressure? Is the pressure difference high? Is the amount of solvent too large, or is the solvent contaminated?
Reply #32016-05-10
It has been determined that it is solvent foaming; today, GE’s defoamer was used, and the pressure difference returned from 74 to 60. Yeah

Where was the defoamer added? In the solvent?

What is solvent foaming, and what are the reasons for it?
