The technical upgrades at Henan Jinkai’s project have yielded results; the daily ammonia production has reached a new high. Author/Source: Henan Jinkai Chemical Investment. Date: August 16, 2019. Click-through rate: 85. Recently, good news came from the Enterprise Management Department of the Second Branch. Since the completion of the company’s major maintenance and the implementation of the energy-saving conversion project, the ammonia production at the Second Branch has been increasing day by day, reaching 3,876 tons per day. This figure represents a record high for summer-time ammonia production since the plant began operations, thereby fully demonstrating the crucial role played by the Second Branch as a “stabilizing force” within the company. You don’t know the difficulty until you go through it. Current product market prices are falling, and the pressure from an economic downturn is unprecedented. As a key technical improvement project this year, figuring out how to increase production and save energy by reducing the overall resistance of the conversion system is a tough challenge that the company needs to overcome urgently. During the major overhaul, the Second Branch organized its staff to work under the scorching sun and intense heat, working overtime to remove, screen, and reinstall the filler in the converter, thereby effectively reducing the resistance in the converter’s bed layer. To reduce the resistance of the heat exchangers, the company mobilized its maintenance resources to increase the diameter of five heat exchanger tubes, and changed the configuration of two heat exchangers from series to parallel, thereby making thorough preparations for integrating the isothermal conversion upgrade project into the system. At 11:00 on August 11, the isothermal conversion unit was officially connected to the system. The cadres and employees of the Second Branch are focused on achieving stable and high yields; they work together hard, seeking solutions in the face of pressures, formulating measures to address existing problems, and taking responsibility to ensure implementation. Company leaders and workshop managers went to the site to work together with the employees to overcome the problem of numerous manual valves at the installation, which made it difficult to operate them ； The control room operators practiced the new procedures over and over again, worked closely with the staff on site, and carefully fine-tuned each piece of data ； Electrical and instrumentation technicians remain on site to address any issues that arise promptly. After 9 hours of hard work, at 20:00 that day, the system was finally stabilized, marking the successful completion of the first-phase transformation and energy-saving renovation project. This resolved the issues of high resistance in the first-phase transformation and high levels of carbon monoxide, thereby laying a solid foundation for the ammonia synthesis system to reach its highest operational load ever.
