“…Akhmetshina et al reported a study on the gas sorbent properties of the DES 1-butyl-3-methyl imidazolium methanesulfonate/urea toward ammonia, hydrogen sulfide and carbon anhydride, with good results relative to the sorption capacity of the ammonia [98]. This study follows the results presented by Zhong [99,100] A different approach to the development of suitable DESs-based systems for trapping VOCs was reported by Di Pietro and co-workers [103]. The Authors demonstrated the possibility to change the ability of cyclodextrin to encapsulate toluene and aniline by performing the process in DES (choline chloride/urea 1:2).…”

Deep Eutectic Systems (DESs) are obtained by combining Hydrogen Bond Acceptors (HBAs) and Hydrogen Bond Donors (HBDs) in specific molar ratios. Since their first appearance in the literature in 2003, they have shown a wide range of applications, ranging from the selective extraction of biomass or metals to medicine, as well as from pollution control systems to catalytic active solvents and co-solvents. The very peculiar physical properties of DESs, such as the elevated density and viscosity, reduced conductivity, improved solvent ability and a peculiar optical behavior, can be exploited for engineering modular systems which cannot be obtained with other non-eutectic mixtures. In the present review, selected DESs research fields, as their use in materials synthesis, as solvents for volatile organic compounds, as ingredients in pharmaceutical formulations and as active solvents and cosolvents in organic synthesis, are reported and discussed in terms of application and future perspectives.

“…In order to evaluate the potential of DPILs for industrial applications of NH 3 absorption, the ILs and deep eutectic solvents (DESs) reported to absorb NH 3 were compared with this work, as shown in Table . The results indicated that the NH 3 solubility in [EtOHim][NTf 2 ] is over 30‐fold greater than that of [Emim][NTf 2 ], and four‐fold greater than that of the functionalized IL [EtOHmim][NTf 2 ], which is superior to any nonmetallic ILs reported so far.…”

BACKGROUND: Ionic liquids have become promising media for the treatment of tail gases containing ammonia (NH 3 ), which causes serious environmental problems and threatens human health. RESULTS:In this work, four dual-functionalized protic ionic liquids (DPILs) [C n OHim]X (n = 1, 2; X = [NTf 2 ] − , [BF 4 ] − , [SCN] − ) with both weak acidity proton and hydroxyl group were designed and synthesized for enhanced NH 3 separation. Among them, the maximum NH 3 molar solubility of 3.11 mol NH 3 mol -1 IL was achieved in [EtOHim][NTf 2 ] at 40°C and atmospheric pressure, and the highest mass solubility of NH 3 could be 0.221 g NH 3 g -1 IL in [EtOHim][SCN]; this is the highest value of any absorbent ever reported under the same conditions. Not only superior NH 3 solubility, along with excellent selectivity of NH 3 /CO 2 (65) and NH 3 / N 2 (104), but also outstanding recyclability was exhibited in DPILs. CONCLUSIONS:The highly efficient performance of NH 3 absorption by DPILs was ascribed to the synergistically physicochemical interaction between weak acidity proton, hydroxyl group and NH 3 , which was confirmed through both spectrum analysis and quantum chemical calculations. This work implied that DPILs have great potentials in NH 3 separation and recovery of NH 3 -containing tail gases.

“…In ref. [ 18 ], the authors determined the solubility of ammonia in deep eutectic solvents consisting of choline chloride (ChCl) and urea taken in three different molar ratios (2:3, 1:2, and 2:5). The experiment was carried out in the temperature range 298.2–353.2 K and pressure from 0 to 300 kPa.…”

An Efficient Technique for Ammonia Capture in the Haber–Bosch Process Loop—Membrane-Assisted Gas Absorption

et al. 2022

View full text Add to dashboard Cite

The present study continues the development and enhancement of a highly efficient unique hybrid technique—membrane-assisted gas absorption in designing the separation unit, which provides the improvement in mass-transfer of a target component during the ammonia capture process from a process loop of the Haber–Bosch technological route. In order to minimize the absorbent volume to membrane area ratio, the special separation cell was designed based on a combination of two types of hollow fiber membranes, dense gas separation membrane and porous pervaporation membrane. The separation performance tests were implemented under two sets of conditions, sweeping the bore (permeate) side of a cell with helium and hydrogen-nitrogen mix. For both cases, the membrane-assisted gas absorption cell demonstrated high separation efficiency, and the ammonia concentration in the permeate was never lower than 81 mol%; meanwhile, under the hydrogen-nitrogen bore sweep conditions, the ammonia concentration in the permeate reached 97.5 mol% in a single-step process. Nevertheless, there is a product purity–recovery rate trade-off, which is a typical issue for separation processes.
