Potential of nanofiltration and reverse osmosis processes for the recovery of high‐concentrated furfural streams

Abstract: BACKGROUND Furfural is an interesting compound that can be produced from renewable and sustainable resources and is used in platform chemicals for the synthesis of biofuels and other chemicals. However, a recovery step is required to separate furfural from lignocellulosic hydrolysates when cellulose‐based raw materials are used. In this work, nanofiltration (NF) and reverse osmosis (RO) processes have been evaluated to purify or concentrate synthetic furfural solutions. RESULTS Two NF membranes (NF90 and NF270… Show more

“…The NF270 membrane showed higher Jv values for olive pomace extracts when compared with the NF90 and Duracid membranes for the lees filters extracts. NF270 had the highest MWCO (400 Da), followed by NF90 (MWCO 200 Da), and Duracid (MWCO 150–200) [ 56 ]. Nunes et al [ 8 ] compared the NF270 and NF90 membranes with olive pomace aqueous extracts with an effective filtration area of 52 cm 2 and obtained higher permeate fluxes with the NF270 membrane due to the lower hydraulic resistance to water transport by the relatively loose semi-aromatic active layer.…”

“…The membranes’ effectiveness was determined by different parameters. The TMP was calculated by Equation (1) [ 56 ]: where P in is the feed stream pressure (bar), P out is the concentrate stream pressure (bar), and P p is the permeate stream pressure (bar).…”
