“…In addition, a different technology was suggested, the use of a membrane (method D) to separate the small CO 2 molecule from the larger organic structures of soybean oil. Membrane separation for extraction has been used in other circumstances (Wang and Shen 2005; Jakubowska et al . 2005).…”

A life cycle assessment (LCA) case study was conducted on the processing of soybeans to soybean oil. Three stages of soybean oil processing are studied in detail: preprocessing, extraction and separation, and postprocessing. For extraction, hexane (current industrial process) and supercritical CO 2 (research and development [R & D] laboratory-scale process) methods are compared in detail. The initial life cycle comparison found that the laboratory-scale CO 2 system was not as good in life cycle impacts as the hexane system. However, reasonable engineering improvements typical of scale-up practices would make the CO 2 technology better than hexane and eliminate the hexane emissions. Utilization of membrane techniques to separate the small molecular CO 2 from the soybean oil hydrocarbon appears to be a much better R & D direction for development. This article illustrates the ability to use life cycle as an aid to R & D to select more advantageous directions for process improvement.

“…The relation between the rate or efficiency of transport of various species through PIMs and their morphology has been already studied. Microstructure of the membranes containing various carriers determines the distribution of a carrier in the polymer matrix and finally affects the efficiency of ion transport and is characterized by different techniques, ,,,− e.g., atomic force microscopy (AFM), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), differential scanning calorimetry (DSC), thermogravimetric analyses (TGA), contact angle measurements, and impedance spectroscopy (IS).…”

Phosphonium ionic liquids (IL), i.e., trihexyl(tetradecyl)phosphonium chloride (Cyphos IL 101), trihexyl(tetradecyl)phosphonium bis(2,4,4-trimethylpentyl)phosphinate (Cyphos IL 104), and tributyl(tetradecyl)phosphonium chloride (Cyphos IL 167), were used as ion carriers in CTA or PVC-based polymer inclusion membranes (PIM). Up to now, the morphology and structure of PIMs with phosphonium ILs have not been characterized in detail. Thus, the following techniques were proposed in this papercontact angle measurements, FT-IR, XRD, DSC, AFM, and SEMto analyze the influence of PIM morphology on the efficiency of Zn(II) transport. CTA-based membranes appeared to be more hydrophilic, with a more expanded and rough surface that allowed better accessibility of the metal ions to the membrane. PVC-based PIMs were more hydrophobic and completely amorphous, and their surface showed less diversity, resulting in worse accessibility. Also, PIM stability after five cycles of transport processes was examined.

“…Under the optimum conditions, the experimental absorbance value was 0.698, not significantly different from the predicted value. At these conditions, the actual protein content of total protein content in the raw material(21.71%) was 10.77%, this was because there were acidic protein and neutral protein in the raw material [14,15].…”

The aim of the study was to investigate bamboo shoots protein extraction. A Box-Behnken design (BBD) was applied through the Response Surface Methodology (RSM) to determine the effects of pH, temperature and solid-liquid ratio during Phyllostachys pubescens bamboo shoots protein extraction. Regression analysis was applied on the data obtained. The more relevant variables were pH, liquid-solid ratio. The coefficient determination (R2 = 0.9258) was good for the second-order model. Maximum yield was 10.77±2.28% obtained when pH, liquid-solid ratio, temperature and extraction time were 12, 32.24, 46.12°C and 20 min, respectively. The result was help to design the process of optimal protein extraction from Phyllostachys pubescens bamboo shoots.
