Effect of Flow Operation Modes on Removal of Acetic Acid from Oil Palm Frond Biomass Hydrolysate using Hollow Fiber Supported Liquid Membrane

Acetic acid (AA) is considered an inhibitor in the oil palm frond (OPF) biomass hydrolysate solution. It can reduce microorganism activity during sugar fermentation using OPF In current study, a hollow fiber supported liquid membrane (HFSLM) system hybrid polyethersulfone-graphene support and organic phase of 0.5 M tri-n-octyl amine carrier 2-ethyl-1-hexanol diluent was used to remove AA. The impregnation time flow operation modes feed strip phases HFSLM configuration were investigated. Mode I operated with inside (HF) lumen stripping at shell side. mode II, entered side HF support. best 4 hours, exhibiting highest AA removal efficiency 80% compared 1 24 hours time. 80.1% 42.4% respectively, 8 (SLM) running applied from real hydrolysate. found that concentration had reduced 6.83 2.01 g/L after SLM process. process did not affect other components, especially compounds
