Phytoremediation stands out as a promising technology for removing heavy metals from contaminated soils. This work focuses on studying the environmental performance of phytoremediation in copper soil located an old Spanish mine using life cycle assessment (LCA) method. For this purpose, Brassica juncea (brown mustard), Medicago sativa (alfalfa) and their rotary cultivation were assessed along with different options managing biomass (landfill disposal cogeneration). In addition, excavation...
Abstract The blocking problems in equipment and flowlines caused by precipitation of wax solids is a well‐known problem large research efforts have been focused on developing procedures dealing with deposition. Among the different alternatives, use chemicals frequently used to inhibit precipitation. presence these compounds modifies size and/or shape paraffinic solids, thus affecting their flow behavior cold properties. In this work, methodology based experimental techniques was developed...
Abstract In this work, a solvent‐based extraction procedure and using supercritical CO 2 to obtain β ‐carotene from Dunaliella salina were compared environmental economic perspectives. Both processes simulated biorefinery scheme in which was obtained the waste biomass used produce energy. The results carry out life‐cycle assessment (LCA). LCA showed that process better terms of energy consumption greenhouse gas emissions. However, low yield technology makes it necessary use large amounts...
A new biorefinery from Arthrospira platensis was proposed to obtain phycocyanin (PC) and a biocrude by hydrothermal liquefaction (HTL). PC is high-added-value phycobiliprotein widely used as food colorant in the nutraceutical pharmaceutical industries. However, use of conventional solvents extraction process purity grade extract are shortcomings bioproduct production. extracted using reusable ionic liquid [EMIM][EtSO4], achieving lowest commercial grade. Therefore, two downstream processes...
Phytoremediation is an in-situ remediation technology based on the ability of plants to fix pollutants from soil. In this sense, such as Festuca arundinacea are a promising for heavy metal removal in contaminated soils. The present work studies phytoremediation Pb soil located Spain using F. by applying Life Cycle Assessment (LCA) approach. Two different options biomass management were assessed: direct disposal security landfill (case 1A) and energy recovery 1B). For latter option,...
Wax precipitation at low temperatures in petroleum mixtures is one of the most important problems flow assurance. Experimental quantification such processes and further characterization precipitated are very difficult extremely time-consuming, therefore, available experimental information scarce usually not confident. In this work, wax samples were from two crude oils different they characterized by optical microscopy, elemental analysis, 1H NMR spectroscopy, differential scanning...
Wax precipitation is one of the most important flow assurance problems. The adequate characterization content and composition waxes present in oil major obstacles dealing with this issue. In work, two different methods for extraction from crude oils are compared. used differ significantly regard to separation asphalthenes. Further purification parafffins was carried out using sequential elution chromatography. n-paraffin distribution determined by gas chromatography along wax melting...
Covalent organic frameworks (COFs) are emerging materials with structural modularity that allows their application in many fields. The aim of this work is to determine the environmental impact using an imine based covalent framework (RT-COF-1) for both surface printing (Case A) and 3D inkjet B) by applying Life Cycle Assessment (LCA) methodology. Experimental data on RT-COF-1 synthesis as well results obtained simulation precursors production, 1,3,5-tris-(4-aminophenyl) benzene (TAPB)...
Wax precipitation and deposition in crude oils can produce flow assurance problems production transportation operations. Knowledge of the wax appearance temperature (WAT) amount that precipitates from oil at different temperatures, i.e., curve (WPC), is necessary for accurate predictions subsea pipelines. The theoretical study process frequently carried out using thermodynamic models. These models require as input information molecular weight n-paraffin distribution oil. commonly determined...
Wax formation by temperature decrease is a serious issue in the petroleum industry, because it makes production difficult and can lead to important economic losses. As result, large effort has been made predict occurrence of this phenomenon as accurately possible. Thermodynamic models are commonly used main parameters involved wax precipitation process. Models with wide basis require most common input information n-paraffin distribution total content (C20+ fraction). The aim work check...
Wax precipitation is one of the most important problems in flow assurance. The correct prediction wax appearance temperature (WAT) and curve (WPC) essential to anticipate potential solutions for this problem. determination both WAT WPC requires reliable data on amount precipitated trapped crude oil remaining these mixtures. estimation latter difficult due scarcity experimental methodologies. In work, a method based differential scanning calorimetry (DSC) was developed determine WPCs were...
Abstract Research into the extraction of phycobiliprotein from Arthrospira platensis is currently ongoing. Most traditional methods include use organic solvents, which negatively affect sustainability process. Ionic liquids (ILs) are a promising alternative for due to their properties as green solvents. In present work an imidazolium‐based IL and sonication were studied carbohydrate extraction. A factorial experimental design was used optimize amount extracted phycocyanin. The maximum yield...
