DISTILLATION OF FUEL OIL KURMANGALIEV A. S. Master’s student, Toraighyrov University, Pavlodar The article discusses options for improving the process of vacuum distillation of fuel oil. Various variants of the process are analyzed. Keywords: vacuum distillation, AUTH, improvement, nozzles, mechanical activation. Currently, due to the modernization and construction of new catalytic cracking plants, it is possible to process vacuum gas oil with a boiling point of up to 360 °C. This, in turn, increases the resource of vacuum gas oil raw materials, as well as increases the viscosity of tar and allows it to be used in a larger composition of road bitumen without oxidation [1, p. 12]. An important task is also to increase the productivity of already built ELOU-AVT installations, including when changing the composition of raw materials, for example, in the direction of increasing the content of light and heavy vacuum gas oil in it. The aim of the work is to find ways to improve the process of vacuum distillation of industrial analog fuel oil at the ELOU-AVT-1 unit with a fuel oil capacity of 2.8 million tons/year. The process is carried out under vacuum in a column equipped with a regular nozzle QtY. The analysis of the production method showed that the main problems arise when providing a high proportion of distillation without noticeable decomposition of hydrocarbons with minimal liquid entrainment to the lower plate, as well as the use of contact devices with low mass transfer efficiency and high hydraulic resistance. To achieve the purpose of the work, we will consider the main directions of modernization of the process of vacuum distillation of fuel oil. The increase in the selection and improvement of the quality of vacuum gas oil in new and upgraded AVT installations is determined by the capabilities of the equipment of the vacuum unit of these installations, as well as through the introduction of a set of measures: |
