Definitions

  • This invention relates to the oil industry and can be used from the refining and petrochemical fields, in particular, to methods for refining and regenerating oils, including used oils.
  • the regeneration process is very flexible, it consists of independent units, easily varying from one case to another.
  • a different combination of stages of the regeneration process allows the use of combinations of these blocks depending on the origin of the used oil, its water content, mechanical and other impurities.
  • the objective of the claimed invention is the regeneration of oils, the disposal of environmentally hazardous waste and the receipt of basic refined oils of the required quality, as well as the simplicity of the process and its hardware design, the use of domestic equipment, the possibility of processing a wide range of oils, including used (automobile, industrial, diesel, energy, etc.) environmental safety, obtaining a high yield of target products.
  • base oils are obtained with a practical lack of metals, water and mechanical impurities having a high viscosity index and higher oxidative stability compared to oils produced from oil using standard technologies.
  • this method uses inexpensive reagents without the use of high-pressure apparatuses.
  • the dried oil is fed to the contact cleaning unit for cleaning with adsorbent and filtration, after which the purified oil is sent to the purified oil park, and the wastewater from the chemical processing unit and coagulation is sent to an oil trap, a mixture of used oils that have passed or failed to coagulate, have passed or have not been chemically processed, have passed or have not gone through vacuum drying, are sent to a feed preparation park for vacuum distillation, the necessary mixing is carried out to obtain homogeneous raw materials of constant quality and fed to vacuum distillation, where light fractions (B) are extracted, which are used as fuel in the furnace, and fuel gases (A) are used to evaporate alkaline effluents (B), and bottoms (G) are isolated, the target oil fractions are pumped out to the vacuum overhead fleet, followed by contact cleaning and filtration, the finished oil fractions are collected in the refined oil fleet, and then sent for mixing with additives the desired
  • Reception of the spent raw materials is carried out in railway, automobile tanks and in two-hundred-barrel barrels.
  • Raw materials are received from automobile tanks by pouring oils of different quality into a three-section recessed tank.
  • an analysis of the resulting oil is performed.
  • the criterion for making a decision on the direction of pumping out is the similarity of a new batch of oil with previously accepted ones in terms of physical and chemical parameters, since changes in the properties of oils occur during the operation of petroleum oils in engines, machines and other equipment. The nature and depth of these changes depends on the working conditions.
  • rectification of oil in a vacuum column is provided.
  • Raw materials for vacuum distillation can serve as refined oil, and base oils coming from the park receiving raw materials.
  • Heavy oil fractions are separated from the bottom of the vacuum column, with which resinous compounds, peroxidized products, and also products of the decomposition of additives are removed.
  • the design of the vacuum column uses a new generation heat and mass transfer nozzle and two stripping columns, which ensures maximum yield of oil fractions of specified parameters (fractional composition, viscosity, flash point, etc.). All obtained base oils are analyzed by the main quality indicators: density, color, kinematic viscosity, conditional viscosity, flash point, water and solids content, acid and alkaline number, pour point, ash content, sulfur content, etc.

Abstract

La présente invention appartient au domaine de l'industrie pétrolière. Dans ce procédé de régénération d'huiles, la collecte des matières premières s'effectue dans un dépôt de collecte de matières premières. Il est possible de collecter séparément les matières premières de qualités différentes. Après une première décantation permettant d'évacuer l'eau et les impuretés mécaniques, les matières premières sont dirigées dans une unité de traitement chimique et de coagulation que l'on alimente avec une quantité prédéfinie d'une solution aqueuse d'un coagulant et de réactifs chimiques. Le mélange de l'huile usagée et de la solution de coagulant est mélangé avec de l'air puis décanté jusqu'à la stratification, après quoi l'huile usagée, en fonction de sa qualité, est écoulée par gravité dans un dépôt intermédiaire puis dans une unité de séchage à vide ou dans un dépôt de préparation de matières premières à la distillation à vide. L'huile déshydratée est acheminée dans une unité de nettoyage de contact à des fins de purification par un adsorbant et de filtrage, après quoi l'huile purifiée est dirigée dans un dépôt d'huile purifiée. Les eaux d'égout provenant de l'unité de traitement chimique et de coagulation sont dirigées dans un piège à pétrole; le mélange d'huiles usagées ayant subi ou n'ayant pas subi la coagulation, le traitement chimique ou le séchage à vide est envoyé dans un dépôt de préparation des matières premières à des fins de distillation à vide. On effectue le mélangeage nécessaire pour obtenir des matières premières homogènes de qualité régulière, et les matières premières sont soumises à une distillation à vide qui permet d'obtenir des fractions légères, utilisées en tant que combustible dans un four; les gaz combustibles sont utilisés pour évaporer les effluents alcalins. On extrait aussi le fond de cuve, on évacue par pompage les fractions d'huile entières à destination du dépôt d'évacuation à vide, et l'on effectue le nettoyage de contact et le filtrage; les fractions d'huile finies sont collectées dans le dépôt d'huile purifiée puis envoyées pour être mélangées avec des additifs.
