Novel process integration for biodiesel blend in membrane reactive divided wall (MRDW) column

Abstract

The paper proposes a novel process integration for biodiesel blend in the Membrane assisted Reactive Divided Wall Distillation (MRDW) column. Biodiesel is a green fuel and grade of biodiesel blend is B20 (%) which consist of 20% biodiesel and rest 80% commercial diesel. Instead of commercial diesel, Tertiary Amyl Ethyl Ether (TAEE) was used as an environment friendly fuel for blending biodiesel. Biodiesel and TAEE were synthesized in a pilot scale reactive distillation column. Dual reactive distillation and MRDW were simulated using aspen plus. B20 (%) limit calculation was performed using feed fl ow rates of both TAEE and biodiesel. MRDW was compared with dual reactive distillation column and it was observed that MRDW is comparatively cost effective and suitable in terms of improved heat integration and fl ow pattern.

Recent Advances in Reactive Distillation

“…Membranes are used in various chemical process industries. For example, carbon membranes are the most common way to separate biodiesel, but zeolite membranes are the best way to separate TAEEs [21].…”
