Fundamental influences of particles on stirred and unstirred venting processes of foaming systems

Henrik LEIMEISTER,Jörg STEINBACH

Frontiers of Chemical Science and Engineering 2014, Volume 8, Issue 2, Pages 141-148 doi: 10.1007/s11705-014-1423-0

Abstract: Venting is the common safety measure to protect plant equipment against excessive overpressure. So far, scenarios in which particles were part of the system and should have been accounted for did ignore their presence; the scenarios were treated like a two-phase system. Current research shows that particles can have a major influence on the venting behaviour. Experimental results indicate that particles affect level swell and relief flow especially of foamy systems. Based on those results four different layers of influence of the particle have been identified and are presented in a first model. Based on this model recommendations for the development of new and more complex models are given.

Polydimethylsiloxane assisted supercritical CO

Weixia Wang, Shuai Zhou, Zhong Xin, Yaoqi Shi, Shicheng Zhao

Frontiers of Chemical Science and Engineering 2016, Volume 10, Issue 3, Pages 396-404 doi: 10.1007/s11705-016-1577-z

Abstract: The effect of PDMS viscosity on the foaming behavior of HMSPP was systematically investigated using supercriticalCO as the foaming agent.These small domains act as bubble nucleation sites and thus may be responsible for the improved foaming
