Editorial Fourth issue of Algerian Journal of Engineering Research: From vegetable cooking oil wastes to biodiesel
Twelve papers were retained for the fourth issue of the Algerian Journal of Engineering Research (AJER) and as usual different process engineering topics were presented. The adopted slogan for this present issue is: ‘From vegetable cooking oil wastes to biodiesel’ due to the ecological impact of green chemistry based processes on many social and economical institutions like university campuses, hospitals, schools, hotels, etc.
The first set of papers dealt with the advanced oxidation processes (AOP) where the first one considered the synthesis and optimization of layered double hydroxide (LDH) and their derivatives containing two transition metals, namely iron and copper, which have an important effect in heterogeneous Fenton oxidation by a classical method of a co-precipitation followed by a calcination. As a model system the degradation of a synthetic dye patent blue v was considered investigating effects of different parameters such as pH, dye initial concentration, H2O2 dose and photocatalyst loading. The results demonstrated the catalyst performance to be in the treatment of wastewaters (Manaa et al).
The second paper dealt with a numerical assessment of chemical reactions occurring in an O2-bubble oscillating in water irradiated by an ultrasonic wave based on simulations for diverse combinations of various parameters such as ultrasound frequency (20–1000 kHz),static pressure (0.5–2 atm) and liquid temperature (20–50 °C), to correlate the production of HO. and hydrogen to the temperature and pressure achieved in the bubble during the strong collapse to reach optimum values (Kerabchi et al).
The third paper considered a heterogeneous photocatalytic treatment of wastewater effluents charged by emergent contaminants such as salicylic acid which was taken as a model contaminant molecule. The process took place in a stirred photocatalytic reactor with TiO2 as the photocatalyst and the effects of catalyst mass, photodegradation time, salicylic acid concentration, pH, CuO content in TiO2 and ionic strength, were investigated (Rabhi et al).
The second set was devoted to innovative processes with the first paper dealing with a non conventional extraction technique based on a maceration assisted by ultrasound to enhance the enrichment of an olive oil with rosemary essential oil, in a clean manner. The advantage of this process was the reduction of processing time from hours or days to few minutes (Benmoussa et al).
The second paper dealt with the formulation and evaluation with respect to specific parameters such as hardness, friability, weight uniformity, drug content uniformity, and disintegration time and drug dissolution rate, of an orally disintegrating tablet containing Amoxicillin trihydrate using three types of Superdisintegrants, namely Croscarmellose sodium, crospovidone and sodium starch glycolate at three different concentrations (0.5, 1 and 2%) by direct compression method. A major result was that with Croscarmellose sodium at 0.5%, a reduced disintegration time of 26s and a very high release rate of 97% in 20 min were achieved (Lammari et al).
The third set of papers considered environmental issues where the first one dealt with the bleaching step of the refining process of crude edible oil which may generate solid materials called spent bleaching earth (SBE) which contained up to 40% (w/w) of oil associated with other impurities, and if not treated, they might cause several management, storage and environmental problems, beside the unpleasant odors that could be produced. The main objective of this study was to contribute to reduce the pollution risk generated by these industrial wastes using a regeneration method based on a heat treatment of the SBE. The material obtained was a mixture
of clay and coal adsorption capacities of the order of those of virgin bleaching earth (VBE) and of L27 activated carbon (Meziti et al).
The next paper considered the elimination by adsorption onto activated carbon prepared from a waste material (Albizzia Julibrissin Pods AJP), of an organic compound, namely Diethyl phthalate (DEP), which is characterized by its harmful effects on the human health and the ecological systems, since it is present in drinking water, mainly due to its widespread use as plasticizer and non-plasticizer and its characteristic not to bind to materials, hence its migration into various systems like surface marine water, freshwater, sediments, etc. ending up in the human (Bouhamidi et al).
The third paper concerned the development of Hydrogels as efficient drug delivery systems, focusing on their classification, preparation and alternatives as cross linking agents, particularly the synthesis of a non toxic hydrogel based on chitosan, examining the relationship between the hydrogel structure and the drug release mechanism (Bensouiki et al).
The fourth and last set dealt with a variety of processes with the objective to either improve the process performance or to valorize waste materials. The first paper considered an experimental study of the shrinkage phenomenon of apple slices during two types of drying, namely: static drying (in an electric regulated oven) and open sun drying (naturally, on one tray) under the meteorological conditions of Ouargla city in the south east of Algeria. The effect of the water content loss of the fruit samples on the dimensions (thickness and diameter) and on the volume were considered, during both the static and sun drying and the results showed that the volume decreased by 80% and 86% of its initial values, respectively. In addition, the drying of apple slices showed an anisotropic shrinkage independently of temperature and therefore a unique shrinkage equation was proposed for both types of drying (Khama et al).
The second paper considered the mixing performance in a batch torus reactor using computational fluid dynamics (CFD) where two impellers were applied and led to completely different flow patterns. The model reliability was assessed by comparison of the obtained results with reported experimental values and it provided an important tool for the study of the effect of the system geometry and operating conditions on the power consumption and mixing energy, indicating in the present case that the classical three-blade marine impeller had the best mixing performances (Bekrentchir et al).
The third paper presented an experimental work for the recycling of vegetable cooking oil wastes issuing from the local university campus kitchens to convert it into biodiesel, by means of a transesterification which is a reversible reaction, hence improving its yield with an excess of alcohol, such as Methanol, and Potassium Hydroxide as a basic catalyst. The oil conversions as well as the required heating were optimized by manipulating the reaction time taking also care to prevent any oil reformation which would affect the production yield.
The obtained results confirmed that this oil waste could be an interesting source for biodiesel production with the required characteristics standards (Kerras et al).
The last paper presented a method for the determination of water and salt permeability of nanofiltration (NF) and reverse osmosis (RO) membranes, basing on the Van der Meer algorithm which can be used for the calculation of transfers across NF and RO membranes for different types and geometries of modules, basing on a weighted calculation of permeability with respect to elementary membrane surface, transmembrane pressure, pressure drop and concentration gradient (Metaiche).
Finally the Chief Editor and his staff would like to thank Professor Bouras Ahmed, the head of University Constantine 3 for the efforts to promote the AJER, as well as the colleagues, the reviewers and the authors who have are contributed to the concretization of the present issue.
