“…This process produces diluted aqueous solutions of furfural and acetic acid. Common separation methods for furfural include distillation (3)(4)(5), solid adsorption (6) and extraction by suitable solvents (7)(8)(9)(10)(11)(12). Distillation of aqueous furfural solution is complicated by the formation of the azeotrope which contains about 36% of furfural at the atmospheric pressure (5).…”

“…The feed was a 500 ppm solution of furfural in water. Equilibrium isotherm measurements were carried out at 308C and have been reported in an earlier publication [5]. Breakthrough adsorption, solvent regeneration, and solvent displacement experiments were carried out at two levels, one using adsorber columns of 11 mm diameter and the other using adsorber columns of 40 mm diameter.…”

“…Earlier studies [3][4][5] have shown that polymeric adsorbents are effective in separating furfural from water. Although these studies have concentrated on equilibrium and kinetic/breakthrough measurements in small diameter columns in the adsorption or loading cycle, the regeneration of the furfural loaded resin adsorbent has not been given adequate attention.…”

Lube refineries in India are facing pollution problems associated with the occasional loss of furfural from their solvent recovery column bottoms in the extraction plant, which constitute both an economic loss and an environmental hazard. Although earlier studies on furfural removal by adsorption on polymeric resins concentrated on equilibrium and kinetic/breakthrough measurements in small diameter columns in the adsorption, the regeneration of the loaded resin adsorbent has not been given adequate attention. This paper focuses on these issues and also includes studies on larger diameter columns with a view to provide data for design of a pilot scale plant for furfural recovery to be set up in a lube complex. The experimental data from adsorption cycle studies indicate that the resin bed is able to treat 28 bed volumes of furfural laden water bringing down the furfural concentration from 500 ppm to less than 10 ppm. The regeneration data indicate the recovery scheme produces an aqueous stream which contains 3% furfural which has to be taken back to the solvent recovery column in the extraction complex. Adsorption and regeneration data have been simulated respectively by the LDF and diffuse wave model.

“…Pure component properties and other required parameters were retrieved with Aspen Plus from NIST ThermoData Engine database. Hayden−O'Connell parameters for MTBE were missing but set equal to parameters (7) where N is the total number of components. The uncertainty for each composition was determined with eq 8 and the uncertainty for each individual mass with eq 9 Tables 4 to 7.…”

In this paper, measured quaternary and ternary liquid−liquid equilibrium (LLE) data for 2-methoxy-2-methylpropane (methyl tert-butyl ether, MTBE) + furfural + acetic acid (HAc) + water are presented. The measured data are presented together with the optimized binary interaction parameters for the utilized UNIQUAC-HOC (Hayden− O'Connell) activity coefficient model. Suitability of MTBE for liquid−liquid extraction of furfural in an industrial use is discussed.
