Cymbopogon Winterianus

The main objective of this study is to improve the mathematical modelling of Cymbopogon winterianus essential oil extraction by steam distillation proposed by Cassel and Vargas by minimum 5% error reduction. Two process variable of steam distillation which are extraction time and raw material state (dry or natural) has been optimized by using factorial experimental planning to obtain high yields of citronella essential oil from twig and leaves of lemongrass species Cymbopogon winterianus (C.winterianus). The optimal condition for maximum yield (0.942%) were found to be an extraction time, 4 hr, state, natural plant. The study of Cassel and Vargas was subsequently continued with five proposed kinetics model of the extraction process. The modelling of the extraction process is optimized by using one adjustable parameter of the model and the adequacy of the fit of the models to the experimental data are analyzed by using three statistical criteria that are correlation coefficient (r) ,the root mean square error (RMSE) and the mean relative deviation modulus (E). The result has shown that the mathematical model developed by Ana based on mass transfer fundamentals is the optimum mathematical model for the extraction of Cymbopogon winterianus essential oil by steam distillation.

Introduction. Common basil (Ocimum basilicum L.) is one of the most valued and widely used spice plants. The highly valued raw material requires properly prepared soil, mainly rich in nutritions. Traditional use of single-component fertilizers, such as nitrochalk, superphosphate and potassium salt does not guarantee its uniform sowing in the field. The multi-component fertilizer is a safer option. Aim. The investigation was performer in order to assess the impact of multi-component fertilizers on the size and some quality features of the yield of common basil in experimental nutrient works. Material and methods. Three experimental nutrient works were performed in 2013-2015 in the cold greenhouse of the Institute of Natural Fibres and Medicinal Plants (Plewiska, Poland) with use of common basil cvar. ”Wala” seedlings. Fresh and dry mass of herb (after drying in a thermal dryer to a constant weight) and the content of essential oil (by steam distillation in the Deryng apparatus). The outcomes were statistically analyzed (analysis of variance). Results. The increase in dry matter of herb was noted with use of Salmag S fertilizer, as compared to the combination with traditional one-component fertilizers, regardless of the level of fertilization. The content of essential oil in the raw material did not depend on the type and size of the fertilizer used. Conclusions. The research results justify the use of specific multicomponent fertilizers in the cultivation of basil and will be implemented into practice (training, consulting) as a part of the introduction of rational fertilization principles.

Pomelo Peel

Pomelo peel-derived essential oils have been gaining popularity due to greater demand for stress relief therapy or hair care therapy. In this study, we first performed optimization of parameters in the pomelo essential oil extraction process on a pilot scale to gain better insights for application in larger scale production. Then extraction kinetics, activation energy, thermodynamics, and essential oil quality during the extraction process were investigated during the steam distillation process. Three experimental conditions including material mass, steam flow rate, and extraction time were taken into consideration in response surface methodology (RSM) optimization. The optimal conditions were found as follows: sample weight of 422 g for one distillation batch, steam flow rate of 2.16 mL/min and extraction time of 106 min with the coefficient of determination R2 of 0.9812. The nonlinear kinetics demonstrated the compatibility of the kinetic model with simultaneous washing and unhindered diffusion with a washing rate constant of 0.1515 min−1 and a diffusion rate constant of 0.0236 min−1. The activation energy of the washing and diffusion process was 167.43 kJ.mol−1 and 96.25 kJ.mol−1, respectively. The thermodynamic value obtained at the ΔG° value was −35.02 kJ.mol−1. The quality of pomelo peel essential oil obtained by steam distillation was characterized by its high limonene content (96.996%), determined by GC-MS.

Introduction. Marigold (Calendula officinalis L.) is an annual plants belongs to Asteraceae family. The species is widespread in the world and have a long tradition of medicinal use with multidirectional action. Aim. The field experiments were carried out to assess the impact of genetic (cultivar) and environmental factors on yielding variability and biosynthesis of essential oil in conditions of conventional cultivation of marigold after using different methods of plantation weeding. Material and methods. The research material were two cultivars of marigold such as Orange King and Indian Prince. The following activity were tested: 1) spraying of Fusilade Forte 150 EC (1 l • ha-1), 2) spraying Fusilade Forte 150 EC (1 l • ha-1) + manual weeding, 3) manual weeding, 4) no weeding – control. The scope of the research included assessment of marigold yield (inflorescence) and determination of the essential oil contents in dry mass of raw material. Results. Regardless of the cultivar, a non-chemical methods (mechanical weeding in interrows and manual in rows) gave the highest efficiency of weed control. Similar results observed after using chemical weeding with manual weeding. In these cases the yields were at least 2.5 times higher than obtained from the control. The total yield of dry mass of inflorescence for the above methods was 6.35 and 5.53 q • ha-1 for Orange King cultivars, slightly lower result obtained for cultivar of Indian Prince (4.81 and 4.12 q • ha-1). It was also shown that the content of essential oil in the raw material ranged from 0.25 to 0.37% and was independent from the cultivar. Conclusions. The Orange King cultivar of marigold yielded better than Indian Prince in analogous methods of plantation weeding. The highest effectiveness of weed plantation was found using a non-chemical method (mechanical weeding in interrows and manual weeding in rows) and using chemical weeding with manual weeding. It was shown that the content of essential oil in the inflorescences of both examined cultivars was similar.

The Impact

The results of calculation of energy efficiency of the variant of technology of converter smelting with preliminary heating of scrap metal in the unit due to burning of solid fuels in modern raw material conditions of the metallurgical enterprise of Ukraine are presented. A critical analysis of the variant of converter smelting technology with the use of preheating of an increased amount of scrap metal in the charge containing briquettes of steel chips in the unit, before pouring processing iron. According to the results of the calculation of the efficiency of use of different types of fuel used for preheating of scrap metal in the unit, the rational type and technology of its use in converter smelting are determined. A direct connection between the chemical composition of briquettes, the level of their preheating and the share in the metal charge on the energy efficiency of the converter process and their chemical heat content has been established. The nature of the temperature distribution in the volume of briquettes from steel shavings, which are a part of the metal charge, is taken into account when they are preheated by oxidation of coal with oxygen supplied through the nozzles of the standard lance. A method for calculating the change in energy consumption of scrap metal during its preheating, taking into account the content of elements in the briquettes and the level of heating. The energy consumption of the converter process with preheating of the metal charge increases in proportion to the level of contamination of briquettes from steel chips with non-metallic inclusions. According to the calculations when heating briquettes by 100—800 degrees in the converter, the increase in energy consumption of the converter process is from 60 to 630 MJ / t and from 445 to 1000 MJ/t for contamination of briquettes with non-metallic inclusions of 2.47 and 7.87 % by weight in accordance. With the reduction of briquette contamination, the efficiency of preheating of the metal charge increases. The share of the impact of the level of briquette contamination on the overall energy efficiency of the converter process is on average 0.3 % of the total energy savings of 1.91—1.92 GJ / t, which is achieved by increasing the share of scrap metal in the charge.

Developing countries are facing population growth, which leads, on the one hand, to increased requirements for buildings and, on the other hand, to the depletion of fossil fuels along with exposure, of people living in those areas, to some detrimental consequences of climate change. Because of these factors, we propose approaches to control energy consumption in buildings. In some countries, the architectures adopted are not adequate to the environment and climate, resulting in discomfort in those buildings, in such circumstances, residents resort to the use of energy systems, such as heating, ventilation, and air conditioning, which leads to exorbitant electricity bills. Housing consumes 40% of the world's energy and is responsible for a third of greenhouse gas emissions. Optimizing energy needs in buildings is a solution to overcome these problems. For this purpose, there are solutions such as: the design of the building characterized by its shape and envelope, while using less energy-consuming equipment. For several years, the building materials sector has been developing with a particular focus on bio-source materials, which are generally materials with good thermal performance. In order to highlight the thermal performance of bio-source materials, we will study the case of Typha Australis which is a plant of the Typhaceae family that grows abundantly in an aquatic environment mainly in the Senegal River valley.Recent studies showed that Typha Australis has good thermal insulation properties. In order to determine the impact of Typha Australis on a building, a dynamic thermal simulation was carried out using the Trnsys software according to specific scenarios, the Typha was mixed with other local materials and used as a wall insulation panel, the result of the study shows that this fiber has allowed us to optimize energy consumption in a building. Mixing Typha with other materials (e. g. clay) is a promising solution for energy efficiency in buildings.

Rosmarinus officinalis is among the most abundant medicinal and aromatic plants in Morocco. There are several factors that influence the yield of quality and quantity of essential oils of this plant. This work focuses on the study, characterization and comparison of the chemical composition of essential oils of Rosmarinus officinalis. The raw material studied is originally from the central part of northern Morocco (Skoura M'Daz region, Eastern Middle Atlas). The essential oils of rosemary were obtained by three different extraction methods : DA: Artisanal distillation, the essential oils were obtained directly from small cooperatives using a very traditional (nonindustrial) method and based on the technique of Steam distillation ; DI: Industrial distillation which is also based on Steam distillation; DC: hydrodistillation by clevenger apparatus Laboratory. The physicochemical characterization of essential oils focuses on the search for the yield of % essential oil with regard to the dry rosemary biomass, density, refractive index and rotatory power. The chemical analyzes were carried out by gas chromatography (GC), they identified 11 components representing more than 99.64% of the essential oil and indicate that the chemotype is 1.8 cineole and is varied according to the method (DI: 48.83%, DA: 41.28% and DC: 51.77%). In conclusion we have shown a quantitative and qualitative loss of essential oils due to the extraction method of essential oils, which has direct repercussions on the economy of rural Morocco and consequently on their sustainable development.
