Process of selective clearing of hydrocarbonic fractions by manufacture of oils is considered. It is shown that its basic appointment is removal of resinous substances and polycyclic aromatic hydrocarbons for the purpose of increase of an index of viscosity of oils, decrease of coking, content of sulphurous compounds, and also simplification of the subsequent dewaxing. The technological scheme of installation of selective clearing is given, the basic directions of perfection and feature of its operation are presented. The characteristic of hydrocarbonic composition of the oil fractions is offered. Ways of improvement of quality of oils and increase of efficiency of their manufacture are considered.
Рассмотрен процесс селективной очистки углеводородных фракций при производстве масел. Показано, что основное его назначение удаление смолистых веществ и полициклических ароматических углеводородов с целью повышения индекса вязкости масел, снижения коксуемости, содержания сернистых соединений, а также облегчения последующего процесса депарафинизации. Дана технологическая схема установки селективной очистки, представлены основные направления совершенствования, особенности ее эксплуатации. Предложена характеристика углеводородного состава масляных фракций. Рассмотрены пути улучшения качества масел и повышения эффективности их производства.
