The results of the analysis of the service life of equipment operating under excess pressure at the Belarusian oil refinery are presented, directions for improving industrial safety when working with this type of equipment are proposed in this study. It was established that fittings with conditional passage up to DN100, the base metal and metal of the welds of the equipment body are the most wearing parts during the service life. Frequent replacement of fittings with a small conditional passage is connected with a small margin between the executive and rejection thicknesses of fittings’ nozzles. The average service life of equipment operating under excessive pressure at the studied enterprise was established.
The article presents the results of work on determining the possibility of obtaining paraffin compounds for various purposes using domestic raw materials. The expediency of using high-molecular purified by-products of oil refineries (the process of dewaxing mineral oils) as components of the candle mass is shown. The proposed method for obtaining candle mass will reduce the burden on the environment, reduce the cost of the process of obtaining candles and expand the base of raw materials for their manufacture through the use of production waste.
The analysis of the state of accidents and injuries during the operation of hazardous production facilities of the Republic of Belarus has been carried out. It has been determined that a significant proportion of the reasons associated with the "human" factor necessitates the formation of behavioral attitudes of employees to comply with industrial safety requirements and the introduction of effective procedures for professional selection and behavioral audit of personnel to work at hazardous production facilities. The selection of methods for diagnosing professionally important qualities of personnel for work at hazardous production facilities of the oil refining industry of the Republic of Belarus was carried out using the example of the profession of an operator of technological installations. A model has been developed for assessing the professional suitability of personnel based on fuzzy inference systems. The architecture of an information system for assessing the professional suitability of personnel for work at hazardous production facilities of the oil refining industry of the Republic of Belarus is proposed.
The article presents the results of the analysis of the effectiveness of express tests for monitoring the current state of engine oil during the period of its operation in an internal combustion engine and determining the limit state of used engine oil. The results of diagnostics by physicochemical, rheological and optical methods of changing the state of fresh motor oil from the lubrication system of a diesel internal combustion engine at regular mileage intervals are presented. A software product project is proposed in the form of a mobile application for diagnosing the state of engine oil in the lubrication system of an internal combustion engine based on paper chromatography using a drop test, which will allow individual motorists to determine the need to replace used engine oil and, as a result, increase the period services of tribocouplings of a motor vehicle and will increase their overhaul period.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
