ABSTRACT The natural gas treatment plant is one source of CO2 emissions into the atmosphere. To tackle this issue, it is probable to inject CO2 into the wells and it can be used for enhanced oil recovery (EOR) application. However, the main setback is the high content of water in acid gas that could be converted to hydrate at high pressure in the pipelines. In this article, two different processes (solvent extraction, stripping gas) with two different solvents mono ethylene glycol (MEG), Tri ethylene glycol (TEG), are simulated in Aspen HYSYS. The stripping gas method is more efficient in terms of energy consumption, consuming 31.8% and 56.8% less energy than solvent extraction method for MEG and TEG solvents, respectively. Hydrate formation analyses showed that applying MEG as a solvent in the stripping gas method leads to a safer operation region. Economic evaluation depicts that the stripping gas method saves the total annual cost by 22.2% compared to solvent extraction. GRAPHICAL ABSTRACT

ABSTRACT Calcium carbonate (CaCO3) is an essential mineral critical for various applications in many industries like plastic, rubber, paint, and paper manufacturing. However, salable CaCO3 products need to meet specific requirements. For the paint and paper manufacturing industries, the whiteness index (WI) of CaCO3 is an important property because it strongly influences the final color of paper and paint products. In this study, the effects of retention time and pulp density on the WI after attrition-scrubbing of calcite tailings were investigated. To increase the whiteness index, an attrition scrubber was used to remove impurities on the CaCO3 surface with different pulp densities—40, 45, 50, 55, 60, and 70% solids—and retention time—10, 15, 20, and 25 min—as process variables. The results of laboratory-scale experiments found that the attrition-scrubbing process improved the whiteness index of CaCO3 tailings and reduced its iron content. The optimum condition was at the pulp density of 55% solids, which was used in the pilot-scale experiments. The results of the pilot-scale tests were consistent with the laboratory-scale, indicating that the attrition-scrubbing process can be used to improve the quality of CaCO3 tailings.

ABSTRACT Aeration effects on membrane filtration of wastewater remain partially explored, as lesser or excessive application often aggravates the fouling. Furthermore, most polymeric membranes are hydrophobic, which facilitates the deposition of foulants and layer formation. There is a need for further investigation on the use of aeration and membrane modifications with a better antifouling property. This study focused on investigating the influence of aeration intensity on the antifouling performance of a modified co-polymerized polyvinylidene-fluoride (PVDF-PEG) fiber using a hydrophilic nano-MgO to treat anaerobically digested palm oil mill effluent (AnT-POME). The aeration intensity was varied to three levels (3,4,5Lmin-1). Both neat and modified membranes obtained their best AnT-POME permeate flux at 4Lmin-1 with a relatively stable value of 28.67 and 89.85 Lm-2 h-1 after 5 h filtration, respectively. The irreversible fouling percentage (IFP) for the neat and modified membrane at 4Lmin-1 aeration intensity, was 66.67% and 12.42%, respectively. This indicates that the neat membrane is more susceptible to fouling. To investigate the changes in the membranes, the fouled membranes were characterized using SEM, FTIR and porosity, then compared with that of the pristine samples. Cake-scaly layers were noticed on the neat membrane. Additionally, both membranes successfully reduced the COD, TDS, TSS, and TN above 60%. GRAPHICAL ABSTRACT

ABSTRACT The demands for Ni-based raw materials increase as Ni–Co–Mn ternary cathode materials become the main axis of the battery industry. Conventional hydrometallurgical process to produce raw materials from Ni ore for battery application is as follows: (i) leaching of metal ions by acid, (ii) solvent extraction process to extract target metals, and (iii) crystallization process to produce final single-metal compound as powder products. The conventional solvent extraction process is a three-circuit process comprising impurity removal, Co extraction, and Ni extraction circuits. Unlike conventional process, in this work, we suggest a simplified two-circuit process to simultaneously extract Ni and Co to produce Ni/Co mixed solution for cathode material precursor production. Accordingly, the efficiency of site utilization can be maximized by reducing the investment cost for the manufacturing process and downsizing mixer-settler facilities. Further, eco-friendly effects such as reducing the consumption of titrants and cutting down the process costs and wastewater discharge can be realized.

ABSTRACT The novel ionic liquid [Aliq–336]+[HCit]− is produced by the reaction of tricaprylylmethyl ammonium chloride, Aliq–336, and tri-sodium citrate. In this investigation, the extraction of Mo(VI) from the nitric acid solution using ([Aliq-336]+[HCit]−) ionic liquid in toluene as a diluent was studied. The effects of various parameters on the extraction process such as shaking time, nitric acid concentration, ionic liquid concentration, hydrogen ion, nitrate ion, Mo(VI) concentration as well as temperature were evaluated. The loading capacity of the prepared ionic liquid was 0.078 mole of Mo(VI) per mole [Aliq-336]+[HCit]−. On the basis of IR spectra and the slope analysis method, the installation of the expected extracted metal species in the organic phase was found to be . As well, the average conditional extraction constant (KCex) for Mo(VI) extraction was 45.96 ± 3.5. The stripping percent of Mo(VI) reached the maximum value (exceeding 99.0%) with 0.5 mol/L sodium acetate as well as 1.0 mol/L of different mineral acids. Based on the obtained results, the prepared ionic liquid in toluene could be used for the effective extraction of molybdenum (VI) from a synthetic mixture of different metal ions found in fission products.

ABSTRACT This paper focuses on the promotion mechanism of sulfonated polyacrylamide (SPAM) on SBX flotation performance on fine pyrite, and verifies the positive effect for a gold ore with pyrite as the main Au-bearing mineral. Micro flotation showed that fine pyrite (−26 + 15 μm) floated poorly compared with coarser ones (−74 + 38 μm), and this cannot be completely filled through increasing the SBX dosage; however, by adding moderate SPAM into the pulp after SBX the flotation of fine pyrite was obviously improved. The real ore flotation revealed that SPAM decreased total reagent dosage and improvement on the concentrate indexes. SBX/SPAM system enabled faster settlement of fine pyrite compared with only SBX or SPAM system, indicating that larger particle size was obtained through hydrophobic and bridging flocculation. Zeta potential results showed that the pre-adsorbed SBX had little effect on the further adsorption of SPAM. Contact angle measurements suggested that the addition of moderate SPAM (50 μg/L) had almost no effect on pyrite surface hydrophobicity, illustrating that SPAM just bridged different fine particles adsorbed SBX rather that covered them. FTIR results showed that the amount of SPAM participating in bridging action was few.
