The first collaboration between Zhengyuan Tower Equipment and Wuhuan Company / Author/Source: Lu’an Zhengyuan Group / Date: 2021-12-22 / Clicks: 12. In November 2021, Zhengyuan Tower Equipment and Wuhuan Company officially signed a contract for the internal components of DN3000 ammonia synthesis towers; these devices will be used in the construction of the second phase of Zhengyuan’s hydrogen energy project. This contract was the first agreement reached between the two companies regarding the second phase of the hydrogen energy project, after numerous discussions. The total value of the contract is 7.75 million yuan. The internal components of this DN3000 ammonia synthesis tower utilize the patented ammonia synthesis technology developed by Zhengyuan Group. The advantage of this technology is that it enables an increase in the production capacity of ammonia synthesis plants, reduces the operating pressure of the system, and simultaneously helps to lower the energy consumption per unit of product produced. The JR-type large-scale low-pressure ammonia synthesis energy-saving technology is the result of the scaling up of Zhengyuan Group’s JR-type ammonia synthesis tower internals and the one-in-one-out temperature-raising ammonia synthesis energy-saving process technology. This technology takes into account the current conditions of China’s nitrogen fertilizer industry; it continues to utilize the direct connection technology between the synthesis tower and the waste heat boiler, which was first adopted by Zhengyuan Group in China. Innovations and improvements have been made on the basis of the original process, resulting in an optimized process flow and more significant energy-saving effects. The JR-type ammonia synthesis reactor internals are a new type of multi-stage adiabatic, inter-stage heat-exchange design developed independently by Zhengyuan Group. In line with the trends in the development of reactor internals both domestically and internationally, these internals optimize the distribution of catalysts across various stages, as well as the heat-exchange processes and the structure of the heat exchangers, thereby significantly improving the utilization rate of the high-pressure space. This approach achieves an optimal balance between the conditions required for the ammonia synthesis reaction and the efficient use of catalysts. Combined with the optimized energy-saving process flow for ammonia synthesis that features one inlet and one outlet for temperature elevation, along with continuous improvements in control technologies, these internals deliver excellent performance. They offer significant technical advantages in terms of catalyst production capacity, the flexibility and effectiveness of production control, catalyst lifespan, and heat recovery efficiency.
