What is the production capacity of Jilin Petrochemical Fertilizer Plant? Should it be imported equipment or domestically produced ones?

It was an old, outdated production line; I wonder what’s become of it now. There’s probably no improvement. The product range is diverse; initially it was synthetic ammonia for fertilizers, and later urea. Too old. I don’t know what’s going on now.

Is Ning referring to the production line that’s 50 years old? That would be considered a cultural relic

The old synthesis gas unit at Jilin Petrochemical Fertilizer Plant was put into operation in May 1982 and has been in use for 39 years; it is primarily responsible for supplying the carbonylation feed gas needed by the butyl octanol production facility. As the total sulfur content in the feed gas continues to increase, the purification efficiency of desulfurization and decarbonization technologies declines. The high sulfur content in the feed gas not only poses safety and environmental hazards to the equipment, but also leads to rising operating costs for the facilities over time. To address this issue, the plant turned its focus inward and concentrated on self-innovation, carrying out modifications to the methanol washing unit of its existing ammonia synthesis facility. It added methanol washing purification equipment for syngas, and upgraded the syngas purification technology in order to reduce costs and increase efficiency in the butyl octyl alcohol production process. At the same time, advanced low-temperature methanol washing technology has replaced outdated desulfurization and decarbonization methods, eliminating potential risks such as aging, corrosion, and leaks in the equipment used in syngas production. This allows for the release of 35 human resources, significantly reducing the costs associated with syngas purification; it is estimated that this will result in annual savings of 28 million yuan.

The old compressors have been placed in the factory courtyard as decorations.

There should also be a granulation tower; it’s considered a cultural relic

The granulation tower and the urea tower are still there.
