DIRECTIONS IN ENERGY SAVING AND REDUCTION OF THE "CARBON FOOTPRINT" IN THE PRODUCTION OF MINERAL PHOSPHORUS-CONTAINING FERTILIZERS

This article discusses technical measures aimed at improving the energy efficiency of the production of granular fertilizers, and relate to one of the two key approaches to the organization of the technological process. The first key approach implies a more complete use of the heat of exothermic reactions. The second key approach implies the use of a set of measures aimed at using (recovering) heat from internal and external heat flows of the installation. The activities of each key approach make it possible to solve the issues of energy saving, reducing natural gas consumption and reducing the "carbon footprint" in the production of mineral phosphorus-containing fertilizers. Examples of technical measures that were carried out or are planned to be implemented at the chemical enterprises with the direct participation of specialists of JSC NIUF at the stage of pre-design study, development of project documentation, start-up and development of design production indicators are given. The most dynamic development of production capacities for the production of mineral phosphorus-containing fertilizers at the chemical enterprises has occurred since the beginning of the tenth years of this century due to the reconstruction of existing systems and the construction of new installations. When developing the organization of production, developing technologies and designing technical re-equipment and new construction, the principles of the best available technologies (BAT) were applied, including the implementation of energy saving measures. The use of energy- and resource-saving approaches in the production of mineral phosphorus-containing fertilizers, the introduction of modern equipment and aggregates into production makes it possible to reduce the specific consumption of natural gas per unit of production, reduce energy consumption, as well as reduce the negative impact on the environment, including reducing the "carbon footprint" in fertilizer production to zero.
