Design of mini-refineries (including projects for the construction of mini-refineries, reconstruction of mini-refineries and modernization of mini-refineries) - is one of the main activities of our Design Institute of Oil and Gas Industry.
The project on mini-refineries referred to construction projects, reconstruction and modernization of small-capacity plants (mini-refinery) of crude oil or recycled oil products (fuel oil, bitumen, gas oil), with little capacity to 500 000 tonnes / year.
Design of mini-refineries (mini-refinery) runs the institute, LLC "PrivolzhskNIPIneft" taking into account customer requirements and conditions on the object.
Mini-refinery project consists of the design documentation (Stage II) - which runs the state or non-state examination of project documentation, as well as working documents (RD stage) and the special sections:
UPN - installation of oil refining (standard equipment UPN: reactor furnace heating materials, a recuperative heat exchanger, distillation column, gas-liquid separator, heat exchanger, air cooler, condenser pump working (raw, pumping products), pump a reserve capacity of raw materials, container for the bottoms, the capacity of reflux, the receiver cracking gases, circulating compressor) and other infrastructural facilities: a drain rack for receiving crude oil by railway transport, tank farm storage of crude oil tank farm storage of finished products (storage tanks of gasoline storage tanks of diesel fuel storage tanks of fuel oil and bitumen and other by-products), car loading dock and rail loading dock for loading processed on a mini-refinery oil.
Biorekc Ltd. for its customers offers a variety of processing plants, allowing the fuel to produce according to GOST or regulations EURO 3,4,5.
To comply with the current regulations in the Russian fuel (it should be the quality of not less than EURO-4) our Institute in designing a mini refinery uses crude oil processing plant (OTP) with recycling.
Introducing a standard number of mini refinery productivity thousand. Tonnes per year:
Mini-refinery for production of motor fuels (oil) are fully equipped modular units (factories) suitable for immediate installation on site and designed to be fully operable within three weeks after the arrival of the equipment to the prepared construction site.
PRODUCT YIELT WITH A MINI REFINERYNAFTA (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.

DESIGN OTHER MINI Refinery
Oil refiningThe 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 ProcessesPrimary 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 .
Oil treatmentOil 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 distillationOil 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.
Material balance of atmospheric distillation of West Siberian oil
Vacuum distillationVacuum 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 processesThe 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:
ReformingCatalytic 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 . 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.
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.
