How to distinguish between small, medium, and large-scale ammonia synthesis? What is the annual production volume considered to be large-scale ammonia synthesis?
An annual production capacity of less than 100,000 tons of synthetic ammonia is considered small-scale; 100,000–300,000 tons falls under medium-scale, while over 300,000 tons is classified as large-scale. This includes plants with production capacities in the ranges of 300,000–520,000 tons, 460,000–800,000 tons, and 600,000–1,040,000 tons.
According to past classifications, a plant with an annual production of 300,000 tons of synthetic ammonia and 520,000 tons of urea was considered a large-scale synthetic ammonia plant.
100,000 tons is considered medium-sized? I rarely go to small ones then.
During the planned economy era, enterprises with a single production unit capable of producing 300,000 tons of ammonia per year were considered large nitrogen fertilizer manufacturers and were directly under the jurisdiction of the former Ministry of Chemical Industry. The production processes and equipment used in these enterprises were largely imported from abroad, resulting in a high degree of automation, advanced process equipment, and large production capacities； These devices are on a similar level to those from abroad in the 1960s and 1970s, and some domestic companies that have purchased used devices in recent years have devices of a similar nature.
