Abstract:

Gas separation, CO2 capture, petrochemical and food industry, are only the most important fields employing membrane technologies as separation processes. The characterization of membrane materials is based on the knowledge of their permeability P and diffusivity D. Although data of P and D are available in literature for a wide group of materials, agreement between the results of the different procedures to measure them, is sometimes poor and may be material-dependent. In this work we present a new versatile experimental set up fabricated to carry out P and D measurements with high accuracy. The apparatus is a high vacuum set up allows the measurements with two methods: static and dynamic. The static method consists in a constant-volume variable-pressure procedure, dynamic one employ a mass spectrometer (MS) to perform a selective and rapidly measurements of transient flux through membranes. Both methods measure P and D. Respect to other apparatus, it present substantial improvements. It is equipped with a spinning rotor gauge, which it is possible to obtain measure with high accuracy. It has a new freestanding membrane assembly that guarantee the same feed and permeate area in order to avoid later diffusion. In the dynamic procedure MS allows to run experiment without sweeping gas to prevent sample diluition which diminishes analytical sensitivity. Finally, it allows permeability measurements in a high range of values, making it available for a wide group of materials for several applications: materials with high and very low permeability (for separation or sealing applications respectively).

Abstract:

Olive-waste cake is a by-product of the Olive oil extraction recognized as a rich resource of phenolic compounds (about 45% of the original Olives’ phenolic content). Recently, in relation to the major interest for natural compounds with biological activities,the interest in the separation and purification of polyphenols from these wastes has remarkably grown. Indeed, polyphenols have been associated with a multitude of health beneficial effects possibly preventing damages and diseases caused by oxidative stress. Pressure-driven membrane processes has been largely investigated in the last years for reducing the organic load of agro-food wastewaters and for recovering of high-added value compounds. This work was aimed at investigating a sustainable process for the purification of polyphenols from Olive-waste cake. It was based on an aqueous extraction step of the Olive-waste cake followed by a fractionation/concentration step through the use of tight ultrafiltration (UF) and nanofiltration (NF) membranes. The aqueous extraction was studied on bench scale evaluating the effect of time and solid-liquid ratio on polyphenols recovery. The performance of flat-sheet polymeric membranes, with different molecular weight cut-off, was evaluated in terms of productivity and selectivity towards total phenols. Fouling index and cleaning efficiency were also analysed in order to determine process feasibility at industrial scale. The whole result allows selecting the suitable membranes to obtain formulations enriched in phenolic compounds of interest for functional foods and functional food ingredients. Preliminary results demonstrate that the combination of aqueous extraction and membrane systems is an effective method to extract and purify phenolic compounds from Olive cakes to produce products that are economically highly valued reducing at the same time environmental issues of Olive waste disposal.

Abstract:

Lignite is an abundant raw coal resource, which is increasingly implemented as a primary energy supply worldwide. However,due to the characteristics of high moisture content, high ash content, high volatile content and low calorific value etc., the direct combustion of lignite resuts in low combustion efficiency, high transportation cost. In order to implement lignite as energy source and increase the utilization efficiency, the upgrading of lignite by discarding and removing moisture prior to direct use is necessary. Coal separation and simultaneously drying technologies have the superiorities of avoiding lignite slimming in separation process and attenuating the adverse effect of liquid bridge between lignite particles on particle diffusion and stratification in the separation process. The pulsed fluidized bed is typical coal separation and drying system, which implements pulsating air flow to promote the diffusion and stratification of particles and improve the dying performance and separation efficiency. In the proposed work, a novel autogenous medium pulsed fluidized bed system was established targeting at separating and simultaneously drying the fine lignite. The core of the system involves: gas heater, pulsating system and fluidized bed with thermocouple measuring equipment. The electrical heater consists of electrical heating tubes. Controller is responsible for setting the range of heating temperature in order to satisfy experimental requirements. In the experiment, the drying process and separation process were conducted simultaneously under different superficial velocities. After each separation, the products were sampled and analyzed in terms of ash content and moisture content. Results show that the calorific capacity have been increased significantly and the moisture content of lignite has been decreased.

Abstract:

With the invention of RHT-alkylation, sulfuric acid alkylation process configuration and equipment provides multiple paradigm shifts and breakthroughs in the technology but keeping same reaction chemistry. The breakthroughs reduce the Capex and Opex in region of 40 to 50% compared to conventional technology; this is not just improvements but major paradigm shift. The process uses a unique educator-mixing device, which reduce the costs and maintenance requirements on stream factor with simple equipment. The unit uses classical coalescers for separating the acid and hydrocarbon from the contactor/reactor effluent, making it a dry process that simplifies the process by reducing equipment items, corrosion and cost. Additionally major breakthrough is in absorbing the auto refrigeration vapors in reactor effluent. This reduce the requirement for compressor saving 20% Capex and 50% of power requirements and operating costs. These are major benefits to the refining industry and should be embraced by the industry to make the competitiveness of the unit. RHT-Iso-octene/iso-octane process provides major economic advantages with simple and smart configuration which enhances the yield and reduces the equipment sizes and utilities. Advances simplify the technology and provide economy of scale.
