Preparation of dual‐layer acetylated methyl cellulose hollow fiber membranes via co‐extrusion using thermally induced phase separation and non‐solvent induced phase separation methods

25-Jul-2015 | Hanna Jang, Du‐Hyun Song, Hye‐Jin Lee, Seong‐Han Lim, In‐Chul Kim, Young‐Nam Kwon, Journal of Applied Polymer Science, 2015

ABSTRACT Dual‐layer acetylated methyl cellulose (AMC) hollow fiber membranes were prepared by coupling the thermally induced phase separation (TIPS) and non‐solvent induced phase separation (NIPS) methods through a co‐extrusion process. The TIPS layer was optimized by investigating the effects ...

Modeling and Analysis of Conventional and Heat‐Integrated Distillation Columns

24-Jul-2015 | Thomas Bisgaard, Jakob Kjøbsted Huusom, Jens Abildskov, AIChE Journal, 2015

ABSTRACT A generic model that can cover diabatic and adiabatic distillation column configurations is presented, with the aim of providing a consistent basis for comparison of alternative distillation column technologies. Both a static and a dynamic formulation of the model, together with a ...
