Main facilities of the first stage of the Complex-16 project were put into service. Complex began to output the first products: methanol made from coal and sulfuric acid made by hydrosulfuric processes of vapor-phase hydrogenation.

1953

First stage facilities are put into service

Complex-16 was conversed, since the process used to produce gasolines from coal could not ensure high productivity of the plants put into operation and required high expenses while return is low, which made gasoline production unprofitable. The complex should be transferred to fuel and chemical sector based on oil processing.

1955

Conversion to oil processing

In order to observe the directives of the CPSU Central Committee meeting, new oil processing and chemistry section—petrochemistry—was created at Complex-16.

1958

First ammonia is produced

In the shop No. 41 of Hydrogenation Plant, first ammonia was produced based on zero block process flow. A decision was made to use 25% aqueous ammonia as fertilizers. First batches of nitrogen fertilizers were sent to the fields of Irkutsk region. However, the first 25 KTPA Ammonia Plant could not meet the fertilizer demands even of Irkutsk region alone. The next step in this direction was the construction of Urea Plant in this year.

History of the Compound Nitrogen Fertilizer Plant begins with the Resolution of the USSR Council of Ministers on construction as a part of the Complex-16. Directorate of the plant under construction is arranged under the Direction of Irkutsk Sovnarkhoz.

In accordance with the Order of Director of Complex-16, Compound Nitrogen Fertilizer Plant No. 8 was established in May, that included plant No. 35 (crystalline urea production) and plant No. 86 (sulfuric acid production), and the facilities being currently retrofitted and constructed: production of ammonia, weak nitric acid, ammonium nitrate, formalin, urea-formaldehyde resins, and strong nitric acid.

1960

Plant formation and urea production

In august, Urea Plant was put into operation. But the capacity of one fertilizer plant was not enough. The two erected columns could produce about 70,000 tons of urea. Production of the first urea was accompanied with substantial waste. In addition, capacity was too small and there were serious process drawbacks.

1961

Ammonia Synthesis Plant is put into service

In December, Ammonia Synthesis Plant No. 34 was put into service.

Plant No. 34's ammonia start-up shift

In January, first tons of liquid ammonia were produced.

1962

1968

First tons of granular urea are produced

In the early January, the first tons of granular urea are produced using complete process flow chart.

Cuprammonium gas purification plant No. 46/48 and sulfuric acid plant No. 86 were put into service.

Storage for ammonium nitrate solution is put into service at the plant. In this relation, the plant personnel became the first in the country. This enabled increasing of product quality and improving operation of interconnected plant workshops.

1969

Storage for ammonium nitrate solution is built

Retrofitting of ammonium nitrate plant is completed. Three final ammonium nitrate melt concentration units are put into operation. These measures resulted in production of ammonium nitrate with improved caking performance. In order to improve grain size distribution of ammonium nitrate, new granulators were installed at the plant. This resulted in improved grain size distribution of ammonium nitrate.

1970

Retrofitting of ammonium nitrate plant

In accordance with the Order of the USSR Petrochemical Industry Ministry dated June 30, 1976, the Angara Petrochemical Complex was reorganized into ANOS PO. Reorganization of production plants has started. As a result, plants No. 46 and No. 34 became a part of Compound Nitrogen Fertilizer Plant. Plants No. 35 and 88 were merged into a single plant No. 35/88. Plants No. 86 and 29 are removed from the plant.

1976

The complex is renamed to ANOS PO

A decision is made to build new large capacity production plants: 450 KTPA Ammonia Plant and 330 KTPA Urea Plant. An order for ANOS PO was issued to make arrangements for Mineral Fertilizer Plant. Since the Mineral Fertilizer Plant was formed, the Compound Nitrogen Fertilizer Plant was named as old site, and the future large capacity Ammonia and Urea Plants were called as new site. Since then, the both mineral fertilizer plants started parallel operation.

1978

Construction of new large capacity production plants

Urea Plant No. 83 was removed from the Compound Nitrogen Fertilizer Plant and included in the Mineral Fertilizer Plant.

1981

Rotation of Plant No. 83

Large capacity Ammonia Plant was put into operation.

1983

Large capacity Ammonia Plant is put into operation

In September, first ammonia was produced from gasoline. The old ammonia process, obsolete and non-environment-friendly, was shut down.

Large capacity Urea Plant is started.

1984

Large capacity Urea Plant is started

In July, Compound Nitrogen Fertilizer Plant and Mineral Fertilizer Plant were merged into a single plant—Nitrogen Fertilizer Plant. This was related, first of all, with the need to reduce the number of workplaces and constant mess in product accounting documentation between the two plants.

1985

Plants are merged

The first stage of automatic control system of the plant was put into service. This system was created for plant No. 85 by specialists of Experimental Automation Design Office managed by E. M. Shlikhter.

1987

After 18 year shutdown, Weak Nitric Acid Unit No. 8 is repaired and put into operation, which allowed to increase ammonium nitrate capacity to 270 KTPA.

A complicated process of transfer to Sibur-Minudobreniya OAO holding has begun. 300 persons were employed by the plant. With the new owner, mass personnel rotation didn’t take place, and key staff could be kept. By this time, two production facilities were in operation at the plant: weak nitric acid and ammonium nitrate.

2007

Transfer to Sibur-Minudobreniya OAO holding

In the first half-year, the plant managed to exceed design capacity and produced 214,000 tons of products. For the entire year, retrofitting and replacement of old equipment took place at the plant. Ammonium nitrate packing system that uses 500/1,000 ton containers was completely automated. Automatic Process Control Systems were introduced at each acid unit, at ammonium nitrate plant, at liquid ammonia drainage and storage section. The fleet of car-lift trucks was completely renewed at the shipping section.
