RESPONSIBLE PRODUCTION IS OUR PRIORITY, TAKING THE NECESSARY ACTIONS TO HAVE INCREASINGLY SUSTAINABLE PROCESSES AND FACILITIES.
Our production process is continuous, so responsible management of natural resources, especially non-renewable resources, is essential for operations. Natural gas and water are basic inputs necessary for the development of our activities.
Air, which provides nitrogen (N), natural gas (CH4) and water (H2O) are the raw materials for producing ammonia (NH3) and carbon dioxide (CO2). From the reaction of these two products, a solution of Urea is obtained which is later thus achieving our final product: Granulated Urea.
(*) The gas consumption corresponds to its use as raw material and fuel.
(**) The decrease in Sodium Hypochlorite and Urea Formaldehyde is due to the two months of Plant Turnaround. The increase in Nitrogen is due to the fact that it was used to inert equipment during the plant shutdown.
The non-potable water (internally referred to as “raw”), which is fed to the complex, is sent to the Utilities Plant to be filtered in the filtration unit. From there, a portion is sent to the cooling tower system, a semi-closed system where it is recirculated, and another portion is sent to the Demineralization Plant to meet strict process requirements for boiler water and process steam. Steam is conditioned to fulfill two main functions: as motive power to drive the turbines of large machines, and as a raw material for the reforming system together with natural gas.
Through heating and the intervention of catalysts, the feedstocks are transformed into carbon and hydrogen oxides, then air is added to obtain nitrogen and oxygen to complete the reaction to carbon dioxide. Subsequently, the carbon dioxide is separated to be sent to the Urea Plant, the hydrogen with the nitrogen provided by compressed air is sent to the synthesis section to produce ammonia. Part of the Ammonia is sent to the Urea Plant to be combined with carbon dioxide, previously separated, to form Urea under certain temperature and pressure conditions
Through separation and concentration processes, a 96% Urea solution is obtained, a condition required for the subsequent granulation process. In the granulators, the Urea is transformed into granules (small spheres of 3 millimeters in diameter), which constitute the final product. The Ammonia not used in the Urea Plant (main product of the Industrial Division of Profertil) is sold as a coolant and raw material in the cosmetics and cleaning industries.
