Analysis of Yung-ching Nitrogen Fertilizer Plant on high-resolution
photography shows that the primary product will be urea fertilizer, with liquid
ammonia and probably aqueous ammonia as secondary products. We have not yet
confirmed that the plant has begun production.
The plant was under construction when it was first observed on photo-
graphy in September 1967. By August 1968 an unidentified processing building
and six support buildings had been constructed. Between August 1968 and
October 1970, a steam plant, coal gas retorts, gas purification equipment,
an ammonia synthesis building, and urea production facilities were added.
The plant was externally complete by October 1970. As of July 1971, it
has not been observed in operation.
This report includes a photograph, a process flow chart, a line drawing
of the plant, and a chronological summary of construction and operational
status.

Yung-ching Nitrogen Fertilizer. Plant is located 3 nautical miles (nm)
northwest of the center of Yung-ching, Kansu Province (see Figure 1).
Electric power is received from the regional grid system. The
Lied -cheng Dam,Hydroelectric Power Plant Lin-chia Gorge
s approximately 4 nm southeast of the plant.
The plant occupies about 19 acres in an irregular-shaped area measuring
approximately 1,'285 by 950 feet overall (see Figures 2 and 3). It is served
by a'spur from the Lan-chou to Yung-ching rail line.
The primary function of the plant is the production of prilled urea
fertilizer. Liquid ammonia and probably aqueous ammonia will be secondary
products. The plant i.s'designed to use coal gas as the source of hydrogen for
the synthesis of ammonia and as a source of carbon dioxide for the production
of urea. Nitrogen for the production of ammonia will be supplied by an air
separation plant. The process flow for the products is shown in Figure 4.
Initial construction activity for the plant was observed in September
1967. By August 1968 an unidentified production building and six support
buildings;.were"present. Between August 1968 and October 1970, a steam
plant,,coal. gas retorts, gas purification equipment, an ammonia synthesis
building; and':urea,.,production facilities were added. The plant was
externally complete by'.October 1970, and no additional construction has
been observed since that time.
As of Ju.ly.1.971,, the plant has not been observed in operation. Coal'
has been observed in'the.coal receiving and storage area since October 1970,
but it may have been' used only for the operation of the steam plant.
