An investigation of oils from new wells of Manavi oil deposit was carried out. Physical and chemical and geochemical parameters, as well as functional groups were determined by IR spectrometry. Using simulative chromatographic distillation of oil from the #12 well naphtha 35-180 °C and diesel fractions were obtained. Individual paraffinic, naphthenic and aromatic hydrocarbons were identified in naphtha by gas chromatographic method and distribution of individual n-paraffinic hydrocarbons in urea concentrate was determined in diesel fraction. The results of the investigation show that due to low content of sulfur, tar- asphaltenic compounds and high yield of light fractions the Manavi oil can be recognized as a high quality paraffinic type of oil. Physical and chemical characteristics, chemical nature and high yield of light fractions outline a good perspective for usage of Manavi deposit oil as a raw material for production of commodity petroleum products like high quality organic solvents, aviation and diesel fuels and various petroleum oils.

Investigation of new wells of Satskhenisi oil (#7, #11, #12, #13, #14) and Manavi oil (#11, #12) was carried out. By IR spectroscopy it was established that Satskhenisi oil belonged to naphtheno-aromatic type and Manavi oil – to paraffinic type of oils. According to distribution of trace elements V, Fe, Ni, Co, Mo, Cu, Pb, Sn, Zn, Sr, Ba, Ti and the ratio V/Ni <1, these oils refer to tertiary types of oils, which is explained by conditions of accumulation and geochemical transformation of the original organic compounds.Using simulation chromatographic distillation of Manavi oil from the #12 well were obtained naphtha and diesel fractions. In naphtha by method of gas-liquid chromatography were identified individual paraffinic, naphthenic and aromatic hydrocarbons and in diesel fraction – individual n-paraffinic hydrocarbons.By low content of sulfur, tar-asphaltene compounds and high yield of light fractions, Satskhensi and Manavi crude oils are high-quality raw material for production of commercial oil products for energy purposes.

The article analyses the candied fruit market in Ukraine and describes the main technological operations pertainingto processing of non-traditional candied products – celery and parsnip roots. Darkening of the roots surface caused bythe enzyme oxidation is one of the problems arising when processing white roots, which leads to worse marketable conditionof the product. To prevent darkening, the developed technology provides for soaking raw material in 1% citric acid solutionimmediately after peeling. To improve the diffusion and osmotic processes and to soften roots before boiling in sugar syrup,the steam blanching has been applied. The constructed Gantt diagram proves that the developed technology can shorten thecandied fruit cooking period. The biochemical indicators of the obtained new products have been studied. It was establishedthat the candied fruit possess the appropriate physical and chemical indicators and original organoleptic properties resulting ina demand by consumers. The results of the taste evaluation of the experimental specimen confirmed a high quality of the products.

And Chemical Properties

The fundamental objectives of this study is to analyzed and compare the physical and chemical properties of pyrolysis products (biochar and bio-oil) derived from two oil palm wastes. Empty fruit bunch (EFB) and mesocarp fibre (MF) were subjected to pyrolysis at a temperature of 400 °C for 2 hours holding time at 10 °C/min heating rate and with nitrogen flow rate of 2 L/min. The result obtained from raw material showed that MF contains a high quantity of hemicellulose and lignin which led to a high yield of bio-oil and biochar respectively, whereby, EFB contained a high content of cellulose. The high content of cellulose in EFB resulted in a high yield of gas compared to fibre. The higher heating value (HHV) of biochar and bio-oil were found to be 28.76 and 19.45 MJkg-1 for MF and, 24.33 and 19.98 MJkg-1 for EFB, respectively. Comparatively, the biochar obtained from MF material has high HHV than EFB material. However, all the biochars derived can be used for briquettes production as coal replacement in the future due to significantly high calorific value as compared to Malaysian sub-bituminous coal which has 24.6 MJkg-1. Furthermore, pyrolysis of any wastes encourages proper sanitation and lead to a healthy environment. It can also serve as a potential solution to the energy crisis in developing countries, Nigeria in particular if bio-oil can be improved to power electricity generation facilities in replacement to diesel.

The apricot is considered as one of the most delicious temperate fruit, a highly appreciated stone fruit and a valuable raw material for processing. The Republic of Serbia is one of the leading apricot producers in Southeast Europe, but the assortment is limited by a small number of cultivars harvested, mostly in the ripening season of ?Magyar kajszi?. In order to introduce the most suitable cultivars in the production, having high yield and high quality for consumption and various forms of processing, introduced and domestic cultivars have been intensively studied. In Serbia, apricots are mostly marketed fresh and processed for jams and spirits, but demand for high-quality dried fruits is increasing. To preserve the nutritional and sensory quality of fresh apricots, choosing the best drying technique is significant, and the most preferred technique is the reduction of moisture through convective drying. The aim of the paper was to compare the potential of the apricot cultivars ?Magyar kajszi?, ?Novosadska rodna?, ?NS-4? and ?NS-6? for dried fruit production by two-phase technology - combined osmotic and convective drying, as well as the profitability of apricot drying on small family farms. Cultivars ?NS-4? and ?Novosadska rodna? were found to be suitable for combined drying technology. The highest score in the sensory evaluation of the dried apricots was given to ?NS-4?, and then to ?Novosadska rodna?. The results indicate that the combined osmotic and convective drying of apricot rather than selling fresh fruits can be a profitable and important added value tool for small family farms.

The conditions for the formation of technological losses of oil and petroleum products during transportation through the main pipelines are considered and it is established that the main sources of these losses are large and small airflows of reservoirs. The value of technological losses from evaporation from tanks depends on a large number of factors, in particular: storage temperatures, pumping rates, tank filling heights, physical and chemical properties of the transported liquid, tanks turnover. Until now, a unified approach to the procedure for determining the qualitative and quantitative composition of technological losses from the evaporation of hydrocarbons during storage has not been developed, which leads to disagreements in assessing the actual losses of energy carriers. According to the analysis, it was found that the best is the calculation method for determining the actual irrecoverable losses of hydrocarbons. Its application involves the use of mathematical relationships that describe the dynamics of evaporation of oil and petroleum products in real conditions. To establish such relationships, it is proposed to develop and implement a unit that enables simulation of the process of evaporation from tanks under various conditions and obtaining experimental data taking into account a combination of a variety of factors that affect the amount of the technological losses.

  The article is devoted to the study of the chemical composition, physical and thermal-pfysical characteristics of damp apple pomaces and the identifying patterns of influence of drying temperature the functional composition and gel-forming ability of pectin. The research is aimed at obtaining initial data for the subsequent calculation of the main technological, hydro-mechanical, thermal, structural and economic characteristics of devices for drying the plant raw materials, ensuring the environmental safety and high quality of pectin-containing raw materials, the reducing heat and energy costs. As a result of the study of the thermal characteristics of apple pomaces, the critical points (temperature conductivity – 16.5 x 10-8 m2/s, thermal conductivity – 0.28 W/m K, heat capacity – 1627 j/(kg K)) at a humidity of 56 % are determined, which characterizing the transition from the extraction of weakly bound moisture to the extraction of moisture with strong bonds (colloidal, adsorption). It was found that the pomaces obtained from apples of late ripening have a higher content of solids (21-23 %), soluble pectin and protopectin (2.5-4.5 %). Dried pomaces obtained from apple varieties of late ripening contain up to 25 % pectin, which allow us to recommend them as a source of raw materials for the production of pectin. The optimum modes of preliminary washing of raw materials are offered, allowing to the remove the ballast substances as much as possible. It is established that when the drying temperature increases, the destructive processes are catalyzed: the strength of the pectin jelly and the uronide component and the degree of pectin esterification are reduced. The optimum drying temperature of damp apple pomaces is 80 0C, at which the quality of pectin extracted from the dried raw materials is maintained as much as possible. It is shown that the most effective for the pectin production is a fraction with a particle size of 3-5 mm, which allow us to extract up to 71 % of pectin from raw materials.
