Production of AB “Achema” consists of over 40 different products. The main raw-material used in the production of ammonia and fertilizers is natural gas. The production of other products includes 75 chemical substances and 18 auxiliary chemical substances not included in the composition of production.
AB "Achema" is continuously developing and modernizing its production technology; all technological processes in the Company are controlled by computer systems. Product formulas are also improved by applying humans and environment friendly substances. The Company is engaged in the continuous development of new high quality products for the present day demanding market.
The main activity of AB "Achema" is the production of fertilizers (urea, ammonium nitrate, liquid nitrogen fertilizers - UAN, calcium ammonium nitrate - CAN, nitrogen fertilizers with sulphur) and other chemical products (ammonia, nitric acid, "AdBlue", formalin, urea formaldehyde resins, etc.).
| Nitric acid is a product mostly used as a composite part of other products. The subject matter of the production process consists of catalytic oxidation of gaseous ammonia with oxygen to produce nitrogen monoxide which in the course of further process turns to nitrogen dioxide after binding with oxygen. The final product is obtained after cooling the obtained nitrogen oxides and absorbing them with chemically treated water. Capacity – 1.650 thousand tons per year. |
| Liquid nitrogen fertilizers (UAN) means liquid fertilizers produced in certain proportion by mixing urea and ammonium nitrate solutions (melts) and diluting them with chemically treated water. The obtained mix is cooled. Capacity – 1.336 thousand tons per year. |
| Ammonia is the most important raw-material for the production of fertilizers. It is obtained from natural gas and air. Some of gas is incinerated to obtain heat and chemical reactions, the other share is purified and turned into liquid and gaseous ammonia via multi-level conversion. Capacity – 1.117 thousand tons per year. |
| Urea – granular, bulk fertilizers produced of liquid ammonia and carbon dioxide. Urea is also used as an ingredient in the production of other products. Capacity – 785 thousand tons per year. |
| Ammonium nitrate (AN) refers to granular bulk fertilizers received by neutralizing nitrogen acid with gaseous ammonia and by adding magnesium nitrate as a stabilizing additive to improve physical properties of the product. Capacity – 651 thousand tons per year. |
| Calcium ammonium nitrate (CAN) is a granular bulk fertilizer. CAN is produced by grinding dolomite and mixing with ammonia nitrate solution. The mix is granulated, dried, sieved, cooled, and conditioned. Capacity – 540 thousand tons per year. |
| “AdBlue” is a liquid additive used in the fuel of diesel engines the production of which is based on the dilution of urea solution with salt-free water. Capacity – 160 thousand tons per year. |
| Urea formaldehyde resins (UFR) and urea melamine formaldehyde resins (UMFR) are produced of formalin, melamine, and urea in two stages. At the first stage, the resins are obtained by polycondensation reaction method, whereas during the second stage, their concentration is increased by using vacuum evaporation. Capacity – 125 thousand tons per year. |
| Formalin is produced of a mix of air, water and methanol in contact apparatus where formaldehyde is produced under high temperature and catalyzers. It is later absorbed with water and results in the formation of formalin. This product is also used as an ingredient in the production of other products. Capacity – 100 thousand tons per year. |
| Basic aluminum sulphate solution - used as a coagulant in natural waters for industrial and human consumption, clarification, wastewater treatment, paper industry. The BAST-M modification uses a Fe2O3 additive that accelerates the above mentioned processes. |
