Urea production plant and process
The patent US12060313B2 outlines a comprehensive design for a plant dedicated to producing urea-containing products. The core of the plant features a high-pressure (HP) synthesis section that includes essential components such as a reactor for synthesizing urea from ammonia (NH3) and carbon dioxide (CO2), a high-pressure stripper, and a high-pressure carbamate condenser. The design incorporates a medium-pressure (MP) treatment unit and an MP dissociator, which operate in parallel to enhance efficiency. The urea synthesis solution from the reactor is split into two flow lines: one directed to the HP stripper and the other bypassing it to the MP dissociator. This configuration allows for effective management of gas and liquid streams, facilitating the production of urea while optimizing resource use.
Additionally, the patent describes methods for integrating an ammonium nitrate section into the plant, which includes a neutralization process that combines nitric acid with ammonia. The design also features a low-pressure (LP) dissociator and various flow lines that connect the different sections of the plant, ensuring a seamless transition of materials. The process emphasizes the importance of maintaining specific molar ratios of NH3 to CO2 during treatment and highlights the potential for modifying existing plants to incorporate these advanced features. Overall, the patent presents a detailed framework aimed at improving the efficiency and output of urea production facilities.
