Purification of Crude Glycerol from Industrial Waste: Experimental . . . . 1061 Journal of Engineering Science and Technology August 2016, Vol. 11(8) The fatty acids salt, detects in CG sample in step 1 and step 2 at frequency hroilmaker cm-1 and at a very low absorbance percentage of 2 % was totally eliminated after step 3.
In this study, the physical and chemical properties of five biodiesel-derived crude glycerol samples were determined. Three methods, including iodometric–periodic acid method, high performance liquid chromatography (HPLC), and gas chromatography (GC), were shown to be suitable for the determination of glycerol content in crude glycerol.
The crude glycerol will be pretreated and heated before entering the main distillation equipment. Gasified glycerol will be temperature controlld and sectionly condensed after first cooling and second cooling, the final product quality after first and second colling will be good, with glycerin content of more than 98%.
involved in plant expansion and upgrades as our customers grew. In addition to 12 fatty alcohol plants, 28 are glycerine recovery and pharma grade glycerin distillation plants, including the world’s largest distillation unit of 600 tpd. We have also designed, engineered and delivered more than 75 Biodiesel plants worldwide and invite you to look
It should be noted that the two feed streams of this separation process, the second transesterification product S1 and the glycerol phase of the first transesterification product S2, are coming from the optimal two-step biodiesel production process of 11,018 kg/h refined sunflower oil (Ye et al., 2010), and its composition data is shown in Table 1.
One route for value-added processing of crude glycerol is to produce pure glycerol, via refining processes, hroilmaker. the “Universal Recovery Strategy” that has been developed for recovery of valuable compounds from food by-products (Galanakis, 2012).
