Adsorptive permeation membrane(APM) is composed of adsorbent crystals and porous polymeric frame. Adsorbent crystal particles are uniformly dispersed across porous PP hollow fiber thickness.
The particles are placed in PP network frame without covering their surface at all. The separation through APM is achieved via selective adsorption onto adsorbent crystal particles. Therefore, the process is a kind of hybrid process of adsorption and permeation.
In comparing with ordinary membrane process, APM process is able to separate gas mixture very effectively. After saturation, APM can be regenerated just by applying vacuum into both inside and outside of hollow fibers.
APM system is designed and engineered through systematical simulation and a sequence of groundwork so as to maximize membrane performance as well as the economical value of the membrane process.
- SepraTek™ Adsorptive permeation membrane
- APM hollow fiber is fabricated by the innovated TIPS process which has been established by SepraTek own. Looking at SEM pictures below, adsorbent particles are just dispersed across porous PP network frame without covering their surface at all.
- Selective adsorption happens on the each adsorbent particles, giving out maximum efficiency of adsorption. Highly porous structure of APM makes it possible to separate gas mixture at low feed pressure with negligible pressure drop across the APM and also possible to easily regenerate APM saturated with selectively adsorbed gas component.
- Scope of supply:
- SepraTek offers a full set of APM system optimized, compromising economical aspect and separation performance. SepraTek also supplies separation system to meet a specific request from client.
