Definitions

  • This invention relates to the petroleum industry and may find application in the petroleum refining and petroleum chemistry industries, particularly in processes for the purification and regeneration of oils, including waste oils.
  • Regeneration is a very flexible process. It consists of independent blocks that can be easily varied according to the specific case. A different allocation of the stages of the regeneration processes makes it possible to exploit the combinations of these blocks depending on the origin of the waste oil, the content of water and the mechanical and other admixtures.
  • a method for the purification of waste oils by means of coagulation is through the WO 8704455, 30.07.1987 , SJU, M (C10M), 175/02.
  • the disadvantage of this invention This is because in this procedure, only the process of coagulation has been treated. The solutions regarding other purification stages of waste oils are missing.
  • the object of the present invention is the regeneration of oils, in the recovery of environmentally harmful waste and in the recovery of purified base oils of appropriate quality and in the simplification of the technological process and hardware equipment, in the use of existing equipment, in the possibility of revising a wide Range of oils including waste oils (automotive, industrial, diesel, energy oils, etc.), in ecological safety and in achieving a high yield of the target products.
  • waste oils automotive, industrial, diesel, energy oils, etc.
  • base oils are obtained in which virtually metals, water and mechanical impurities are missing.
  • the oils have a high viscosity index and a higher oxidation stability compared to those made from petroleum Oils according to the standard technologies.
  • this method uses inexpensive reagents without the use of high pressure equipment.
  • the following complex is used in the oil regeneration process: a group (1) for taking over the raw material, a block (2) for chemical processing and coagulation, an intermediate group (3), a group (7) for Preparation of the raw material for vacuum acceleration, a block (4) for vacuum drying, a block (10) for evaporating the outflows, a block (8) for vacuum acceleration with a furnace (9), a petroleum collecting device (11), a block (5) for contact cleaning and filtration, a group (6) for the vacuum drains, a group (12) for purified oil, a block (13) for mixing and dispensing finished oils.
  • the acquisition of the raw material in the group takes place to take over the raw material. There is the possibility of the shared takeover of the raw material of different quality.
  • the raw material is forwarded to the chemical processing and coagulation block after removal of a primary sediment of water and mechanical admixtures. Therein, a design amount of the water solution is passed by coagulant and chemical reagents. The mixture of the used oil and the solution of the coagulant is mixed with air and clarified until stratification. Then, depending on the quality, the cleaned oil is forwarded to the intermediate group in the self-run and then to the vacuum drying block or to the group preparing the raw material for the vacuum acceleration. The dried oil is added to the block
  • the purified oil is fed to the group of purified oil.
  • the effluents from the chemical processing and coagulation block are directed to the oil recovery device.
  • the mixture of waste oils subjected to coagulation or not subjected to the chemical treatment or not and subjected to vacuum drying or not is sent to the group for preparing the raw material for the vacuum acceleration. There is the necessary mixing for the production of a similar raw material of constant quality.
  • there is a vacuum acceleration in which the light fractions (B) are separated, which are used as fuel in the furnace.
  • the fuel gases (A) are used for evaporating the alkaline effluents (E). It is also a bubble residue ( ⁇ ) singled out.
  • the target oil fractions are drawn off into the group of vacuum fractions with a subsequent contact cleaning and filtering.
  • the finished oil fractions are collected in the purified oil group and then passed to a required recipe for mixing with additives.
  • the takeover of the used raw material takes place in railway and motor vehicle cisterns and in 200-liter-tons.
  • the takeover of the raw material from the car cisterns takes place by means of the process of different quality oils in a 3-section container with recess.
  • the extracted oil is analyzed.
  • the criterion for deciding the direction of pumping out is the similarity of the new oil batch with the previously accepted batches according to physicochemical characteristics, as the properties of the oils change when petroleum oils are used in engines, machinery and other equipment. The character and size of these changes depend on the working conditions.
  • the first stage of regeneration of the waste oils begins in the course of settling in the raw material containers equipped with a heating system in which the precipitation of the weighed mechanical particles from the oil and the micro-water droplets takes place under the action of gravitational forces.
  • the effluents produced in the course of settling with admixtures of petroleum products reach the oil collecting device.
  • the mixture of the waste oil and the solution of the coagulant are mixed with air, which in the lower part of the coagulation device from a fan over a special nozzle comes at a temperature of 80 - 85 ° C within 0.5 - 1.5 hours.
  • the solution in the coagulation device is stratified into two layers.
  • the lower layer consists mainly of water and waste from the coagulation process, while the upper layer consists mainly of oil with a small amount (up to 5%) of water.
  • the purified oil from the coagulation device is routed in the self-run in the intermediate group or in the product group.
  • the raw material passes directly to the block for vacuum drying from the intermediate group. Under vacuum, the separation of water vapor at elevated temperature takes place.
  • the dried oil passing through the coagulation device is passed, depending on the quality of the product, for vacuum rectification (group for preparing the raw material for the vacuum acceleration) and / or for the subsequent contact cleaning by means of a bleaching clay.
  • the main factors on which the effectiveness of the process of adsorption depends are the temperature and the contact time.
  • the process of mixing the oil with the bleaching clay takes place at a temperature of 60-150 ° C with a subsequent filtration through a frame filter. After cleaning, the products meet the quality requirements of the base oils and can be used for the further preparation of the product oils.
  • a rectification of the oil in a vacuum column (acceleration, rectification) is provided.
  • a raw material for the vacuum acceleration can serve both the purified oil, as well as the base oils, which come from the group to take over the raw material.
  • From the lower part of the vacuum column separate the heavy oil fractions with which resinous compounds, overoxidized products and decomposition products of the additives depart.
  • the construction of the vacuum column become a dressingstoff
  • All base oils obtained are analyzed according to the main values of quality: density, color, kinematic viscosity, conventional viscosity, ignition temperature, water and mechanical admixtures, acidity and alkalinity, pour point, ash value, sulfur content, etc.
