    NAFTA (straight-run gasoline mini refineries) - A typical final boiling point naphtha - from 110 ° C to 185 ° C. This hydrocarbon fraction UMT is divided into two components - naphtha and Nefras. Naphtha is then used as the basic component in the production of high-octane gasoline. Diesel fractions (distillate MINI refinery) - Typical boiling temperature range of the product is in the range from about 185 ° C to 340 ° C. The product was further subjected to distillation to separate the kerosene (naphtha) and diesel fuel. Depending on the customer's requirements can be produced arctic, winter or summer diesel fuel.
    Residual fraction (straight-run fuel oil from refineries MINI) - a fraction of the primary distillation after which heavy distillates, with an initial boiling point of about 320 ° C. This product is commonly used in the production of various grades of naval fuel and fuel oil.
    During the processing of the conventional crude oil refinery with a small specific gravity to 0.865 unit will operate at rated power, and there will be approximately 20% by volume. light naphtha and gasoline (Nefras), 30% by volume. middle distillate (kerosene and diesel fraction) and 50% of the residual fraction (virgin oil). The actual production capacity of mini refinery product yields as a percentage and their boiling points vary depending on the specific characteristics of the crude oil used is supplied on a mini refinery. After receiving the data on the composition of crude oil is necessary to provide the yields of products that can be produced on the mini refineries and carry out a mini refinery modifications to meet the specific needs and requirements of the design.
    Design BIOREKC OOO is ready to provide the design of any additional equipment for further processing of the product streams, such as middle distillate hydrotreater, catalytic reforming, vacuum distillation and stabilization of naphtha.

  • Oil refining

    The purpose of refining (refining) - production of petroleum products, especially various types of fuel (automotive, aviation, boiler and so on. D.) And raw materials for further chemical processing.
    Primary Processes
    Primary treatment processes do not involve changes in chemical and oil are its physical separation into fractions. First, fishing oil passes the primary cleaning process oil produced from the gas, water and solids - this process is called primary oil separation [1].
    Oil treatment
    Oil is supplied to the refinery in the form prepared for transport. At the plant it is subjected to further purification from mechanical impurities, removal of dissolved light hydrocarbons (C1-C4) and dehydration electric desalting plant (CDU).
    Atmospheric distillation
    Oil enters the distillation column for atmospheric distillation (distillation under atmospheric pressure), where it is separated into several fractions: the light and heavy gasoline fractions, kerosene fraction, a diesel fraction and an atmospheric distillation residue - oil. The quality of the fractions does not meet the requirements of commercial oil, so the fraction is further (secondary) processing.

  • Gasoline fraction
  • Kerosene
  • Diesel fuel

  • Losses
    Vacuum distillation
    Vacuum distillation - the process of distillation of oil (atmospheric distillation residue) fractions suitable for processing into motor fuel, oils, waxes and ceresins and other refined products and petrochemical synthesis. The remaining residue was then called the heavy tar. It can serve as raw material for production of bitumen.
    Secondary processes
    The purpose of the secondary process is to increase the amount of produced motor fuels, they are associated with the chemical modification of hydrocarbon molecules that make up the oil, usually to their conversion to more convenient forms for oxidation.
    According to its directions, all secondary processes can be divided into 3 types:
  • Deepens: catalytic cracking, thermal cracking, visbreaking, delayed coking, hydrocracking, the production of bitumen, etc.
  • Ennobling: reforming, hydrotreating, isomerization, etc.
  • Other: Processes for the production of oils, MTBE, alkylation, aromatic hydrocarbons production, etc.
  • Reforming

    Catalytic reforming - catalytic aromatization of petroleum products (increase in the content arena as a result of the reaction of formation of aromatic hydrocarbons). Reformed gasoline fraction are subjected to boiling range 85-180 ° C [2]. As a result, the reforming gasoline fraction enriched with aromatic compounds and the octane number is increased to about 85. The resulting product (reformate) is used as a component for the production of gasoline and as raw material for extracting aromatics.
  • Hydrotreating
  • Catalytic Cracking
  • Catalytic cracking - catalytic thermal refining process of petroleum fractions to produce high octane gasoline component and unsaturated fatty gases. The raw material for catalytic cracking unit are atmospheric and light vacuum gas oil, an object of the process is the splitting of heavy hydrocarbon molecules, which would use them for the production of fuel.
    During cracking, a large amount of fatty (propane-butane) gases are separated into individual fractions, and are mostly used in tertiary processes at the refinery. The main cracking products are pentane-hexane fraction (ie. N. Natural gasoline) and naphtha cracking which are used as components of gasoline. The residue cracking unit is a component of fuel oil.
