Meifeng ammonia plant continuous operation record refresh

On February 19, Sichuan Meifeng Chemical Industry Co., Ltd. officially released the news. As of February 12, the company's annual output of 200,000 tons of synthetic ammonia plant has been running for 377 days, creating a new record for the operation of similar domestic devices, reaching the international advanced level. .

Chen Run, deputy secretary of Sichuan Meifeng Party Committee, told the reporter that the device has been operating continuously for 377 days, relying on more than 20 new technologies independently developed by the company in recent years. It has continuously optimized the production process and equipment through technological transformation to make the ammonia plant To achieve "safe, stable, long, full, excellent" operation.

According to reports, the company studied and established a low-energy production process model, through the material and heat balance and chemical balance analysis, independently developed the 2011 annual national scientific and technological progress second prize of large-scale ammonia synthesis gas device technology and energy optimization technology The process flow with the best technical and economic indicators, and the large-scale production of large-scale ammonia plants with low energy consumption, excellent performance, and stable operation made the integrated energy consumption per ton of ammonia reduced from 1467 kg of standard coal to 1,054 kg of standard coal.

The shortage of natural gas is a common problem encountered in the long-term operation of production facilities of gas-headed enterprises in recent years. In order to solve the problem that the pressure drop is less than 0.5 MPa, the natural gas compressor cannot play its due role. After analyzing and validating the technical parameters of the natural gas compressor and the production start-up mode, the company reconstructs a section of the natural gas compressor to make the natural gas pressure. In the case of 0.45-0.55 MPa, the load can be increased by more than 1000 kg/h, and when the amount of ammonia produced is 2.2 tons/hour, the annual profit increase is 13 million yuan.

In order to solve the problem of the high temperature of the joint compressor and the lack of process air in the summer, the company’s engineers and technicians boldly innovated and repeated experiments to implement the water jacketing of the outlet of the four compressors. Technological reforms have achieved immediate results: the temperature of a section of the joint compressor air is directly reduced by 10°C, and there is no need to increase air compressors in the summer, which reduces the energy consumption. What is more important is that the equipment operates more safely and the device's production capacity is fully utilized.

The predecessor of Sichuan Meifeng was a small nitrogenous fertilizer company in the county. The original equipment was the conventional technology of atmospheric pressure batch gasification, high-pressure ammonia synthesis, and aqueous solution full-cycle urea using natural gas as raw materials in the 1970s. The production scale was small and the technology was behind. , Low equipment efficiency, poor economic efficiency, lack of market competitiveness. After more than 30 years of development, the company has continuously improved the scientific and technological innovation system. At present, it has set up state-level postdoctoral scientific research stations, national agrochemical service centers, and provincial-level enterprise technology centers, and continues to use advanced technologies to transform and upgrade traditional industries.

 Hongsei Industrial Oil Cooler uses the principle of evaporation and absorption of cold coal to perform cooling work. The oil pump draws oil from the machine's oil tank to the refrigeration system for heat exchange. The cooled hydraulic oil is then cooled by oil.

The machine oil return line is returned to the machine oil tank, and the oil temperature of the entire oil continues to decrease through the continuous circulation of the oil.
