Oil processing units form the basis of Antipinsky Oil Refinery CJSC. The refinery comprises common facilities intended to produce oil, provide the processing units with energy sources, ensure quality control over processes, raw materials and finished products, provide the refinery with water, heat and electric energy. The refinery is connected to main oil pipelines of Transneft JSC at the oil pumping station Tyumen-3 and has a crude oil delivery and acceptance point with a LACT unit and oil metering station No.1006. There are 2 both-way railway tank filling racks, 3 oil and oil-stock discharging racks, 2 road tanker filling racks, a unified network-integrated automated control system, high-speed external telecommunication and mailbox channels.

Due to the fact that construction of a refinery with the maximum possible oil processing depth producing the complete range of high-quality engine fuels requires significant capital investments, refineries are constructed in several phases. Each phase implies organization of a complete production cycle for oil to be processed and a selection of oil products of predetermined quality to be shipped to consumers. That is the development mode chosen by Antipinsky Oil Refinery CJSC.

Its workflow phases are as follows:

Workflow Phase I:

Installations: ELOU-AT-1, storage unit 52,000 m3.
Processing depth: 55% - 57%.
Original crude oil throughput: over 400 thousand tons per year.

Crude oil throughput after re-equipment in 2008 was about 800 thousand tons per year.

Workflow Phase II (operated since May 2010):

Installations: ELOU-AT-2, gasoline stabilizer, storage unit 120,000 m3 (total capacity 172,000 m3).
Processing depth: 55% - 57%.
Crude oil throughput: 2.75 million tons per year in 2010. 3.3 million tons per year expected in 2011 (total refinery capacity is over 3.5 million tons per year, 4.1 million tons expected in 2011).

Workflow Phase III:

Workflow phase III is intended to increase capacity of the refinery in primary crude oil processing up to 4 million tons per year with the maximum processing depth and to enable production of Euro-5 oil products.

Phase III start-up is expected in 2012 - 2015.

The first stage of workflow phase III will be the start-up of ELOU-AT-3 unit with the capacity of 3 million tons per year which is going to increase the total refinery capacity up to 7 million tons per year. For diesel fuel quality to comply with Euro-5 standards and for the necessary freezing point to be ensured so that winter and polar diesel fuels can be produced, a diesel hydrotreating unit with a dewaxing module will be constructed which requires construction of hydrogen production units, gas amine treatment systems and sulphur production units as well. The project is to be implemented by 2013.

At the second stage of workflow phase III the main targets are deeper oil processing, increase in the outcome of light oil products and higher quality of the total production range. The targets will be achieved by commissioning of fuel oil vacuum distillation units, deferred tar carbonization units, reforming units, isomerization units and gas fractionation units to enable proper selection of light oil products and up to 94% deeper oil processing. The reforming unit will provide for compliance of gasoline quality with Euro-5 standards (for the range of gasolines: A-95, A-98). Another hydrogen and sulphur production unit will be introduced to ensure regular operation of the refinery. The project is to be implemented by 2015.
