Naftas produktu tranzīta stacija “Ilūkste” (turpmāk TS) nodrošina naftas produkta (turpmāk NP) dīzeļdegvielas plūsmu cauruļvadā no Baltkrievijas līdz Ventspilij. No 1970. gada līdz 1996. gadam TS veica arī NP iepildīšanu dzelzceļa cisternās. Tad notika NP noplūdes zem un pie dzelzceļa estakādes. Izveidojās pazemes ūdens piesārņojums ar NP, kas kā peldošs slānis (turpmāk NPPS) sasniedza Ilūkstes upes stāvo krastu. Lai novērstu NP iekļūšanu upē, te tika izrakts NP savākšanas dīķis, no kura varēja aizvākt NP. Piesārņotās teritorijas sanācija sākās 1996. gadā, un tā turpinās arī šobrīd. Kā īpašnieks šos darbus finansē un uzrauga SIA “LatRosTrans”. Kopš 2000. gada sanācijas darbus veic a/s “VentEko”. Šobrīd, pateicoties abu organizāciju sekmīgai ilgstošai sadarbībai un efektīvu NP savākšanas ierīču izmantošanai, piesārņotajā teritorijā praktiski nav NPPS. Diemžēl vēl ilgu laiku piesārņojumu, šķīstot ūdenī, radīs nekustīgā NP daļa gruntī. Rīgas Tehniskās universitātes (RTU) zinātnieki 1997. gadā izveidoja piesārņotās teritorijas hidroģeoloģisko modeli. Izmantojot šo modeli un programmatūru “ARMOS”, izdevās atrast galvenās NP noplūdes avotu. Modelēšana prognozēja, ka pašnotecē 25 gadu laikā NP var ieplūst savākšanas dīķī. RTU 2018. gadā novērtēja sanācijas rezultātus un konstatēja, ka tie visumā atbilst 1997. gada prognozei. Galvenās atšķirības skaidrojamas ar atkārtotām NP noplūdēm. Pieredze, kas iegūta TS “Ilūkste” teritorijas sanācijas gaitā, apstiprina modelēšanas metožu izmantošanas lietderību, uzsākot vides atveseļošanas pasākumu īstenošanu. The Ilukste oil transit station pipelines ensure the flow of diesel fuel from Belarus to the town Ventspils in Latvia. In 1970–1996, the station also filled fuel (oil) in railway tanks, which resulted in oil leakages. Due to this, the groundwater under the railway terminal routes was contaminated. The groundwater flow enters the nearby Ilukste river. Fortunately, oil discharged over the ground from a steep bank before the river. To prevent the oil inflow into the river, a special pond was dug for its intercepting. Later, in order to divert the oil discharge underground, the horizontal drain for catching oil was installed before the pond.In 1996, remediation of the oil-contaminated station area started, which is followed up until now. The work was supervised and financed by the station owner “LatRosTrans” Ltd. Since 2000, the site sanitation was performed by the company “VentEko”.

In this study, the atomization of heavy fuel oil (Mazut) and diesel fuel at different pressures is compared experimentally. Also, the effects of temperature on the Mazut fuel atomization are investigated experimentally. Mass flow rate, discharge coefficient, wavelength, liquid film thickness, ligament diameter, spray angle, breakup length, and sature mean diameter are obtained for the Mazut and diesel fuel. Fuels spray images at different pressures and temperatures are recorded using the shadowgraphy method and analyzed by the image processing technique. Error analysis is performed for the experiments, and the percentage of uncertainty for each parameter is reported. The experimental results are compared with the theoretical results. Also, Curves are proposed and plotted to predict changes in the behavior of atomization parameters. Diesel fuel has less viscosity than Mazut fuel. Diesel fuel has shorter breakup length, wavelength, liquid film thickness, and sature mean diameter than Mazut fuel at the same pressure. Diesel fuel has a larger spray angle and a larger discharge coefficient than Mazut fuel at the same pressure. As the pressure and temperature increase, fuel atomization improves. The viscosity of Mazut fuel is decreased by temperature increase. As the fuel injection pressure and temperature increase, breakup length, wavelength, liquid film thickness, and sature mean diameter decrease; also, spray angle increases.

The Oil Refinery of Heydar Aliyev was created in July 1953 as a new oil refining plant Baki. The combined atmospheric vacuum plant is the main plant at the oil refining factory and its starting capacity produces 6 million tons of crude oil. In 2010, 43,000 tons A-98, 1.18 tons of A-92 and 19,700 tons of gasoline A-80. At the same time, 600 400t kerosene, 214,000 diesel fuels, 214,000 tons. Liquid gas, 267 500t coke and 220 600t. With this investigation, the history of the oil refinery and the details of modernization were considered. 21 out of 24 types of Azerbaijani oil are processed at the Baku Oil Refinery named after Heydar Aliyev, of which 15 types of oil products, including gasoline, aviation kerosene, diesel fuel, fuel oil, petroleum coke, etc. are produced. The plant fully meets the needs of the republic in oil products. In addition, 45% of oil products are exported to foreign countries. Key words: Azerbaijani, oil, recycling, factory, modernization

The heat values of waste mineral oils are equal to the heat value of the fuel oil. However, heat value alone is not sufficient for the use of waste mineral oils. as fuel. However, the critical physical properties of fuels such as density and viscosity need to be adapted to the system in order to be used. In this study, the engine oils used in the first 10,000 km of the vehicles were used as waste mineral oil. An organic-based Mn additive was synthesized to improve the properties of the waste mineral oil. It was observed that mixing the Mn additive with the waste mineral oil at different doses (4, 8, 12 and 16 ppm) improves the viscosity of the waste oil and the flash point. The resulting fuel was evaluated for emission using different loads in a 5 kW capacity generator to compare the fuel with standard diesel fuel and to determine the effect of Mn addition. In the experimental study, it was observed that the emission characteristics of the fuel obtained from waste mineral oil were worse than diesel fuel, but some improvement with Mn addition. As a result, we found that the use of waste mineral oils in engines in fuel standards was not appropriate, but may be improved with additives.

Papaya Seed

Fuel oil is one of the important parts to support daily activities. The demand for fuel oil is increasing every year. Therefore, the search for the latest energy source is continuously conducted. Carica papaya L. seed oil is investigated as a renewable energy source replacement part of petroleum diesel fuel. C. papaya seed oil obtained through the extraction process using soxhlet method with n-hexane solvent. Then produce methylester by means of transesterification using 1 % NaOH catalyst and 20 % methanol of the weight of the oil and stirred at 400 rpm for 1 h. A mixture consisting of 10 % C. papaya seed biodiesel and 90 % petroleum diesel fuel, called CPSB-10, produces fuel properties that meet the specified standards by the Indonesian Directorate General of Oil and Gas. From the result of the performance test in a diesel test engine, the maximum brake power and brake thermal are consecutively 30.6 kW and 140.23 N m, the lowest sfc is 268 g kW–1 h–1, and the highest brake thermal efficiency is 32 %.
