Ningmei ammonia synthesis plant exceeded the design capacity for the first time

As of November 2, the ammonia synthesis plant of Ningxia Coal Industry Olefin No.
2 Company has produced a total of 150,200 tons of liquid ammonia products this year, completing the annual production task target
58 days ahead of schedule.
This is also the first time since the plant was put into operation, it has reached and exceeded the design capacity
of 150,000 tons/year.

The company's ammonia synthesis plant undertakes the supply
task of liquid ammonia required for desulfurization and denitrification of boilers in the Ningmei coal chemical plate.
It is understood that since it was put into operation in 2017, the ammonia synthesis plant has maintained a low-load operation
of about 50% under the premise of ensuring the completion of production tasks.
Since 2021, as the sales price of liquid ammonia products continues to rise and the market situation improves, the company has changed the ammonia synthesis plant from the original smooth operation mode that only meets the park's own supply to safe and full-load operation
.
In September and October this year, the production of liquid ammonia exceeded 15,400 tons for two consecutive months, repeatedly refreshing the record of production in history
.

In order to ensure the safe operation of the plant during the load lifting period, the company thoroughly sorted out the operating procedures and various unforeseen risk factors, organized a research meeting to evaluate, and compiled the "Load Adjustment Plan for Ammonia Synthesis Plant" in detail to ensure that the load lifting process was carried out
in a safe, phased and orderly manner.
At the same time, they continue to optimize the liquid ammonia production system, by increasing the alarm value of methane at the outlet of pressure swing adsorption (PSA), reducing the internal gas cycle time of the PSA unit, the hydrogen recovery rate has increased from 94.
4% to 95.
6%, saving about 350,000 yuan throughout the year, ensuring the stability
of the feed gas from the source.
In addition, they also sent the PSA unit analysis gas to the fuel gas pipeline network, and as of October 31, a total of 10.
38 million standard cubic meters of analytical gas was recovered, increasing efficiency by 15.
57 million yuan
