Analysis of the Nan-ching Phosphorous Fertilizer Plant in China on high-
resolution photography shows that the primary products of the plant are super-
phosphate and probably triple superphosphate fertilizers. Secondary products
include sulfuric acid, and probably phosphoric acid and gypsum. A limited
quantity of elemental phosphorus is probably produced. Also, phosphorus-based
compounds such as?insecticides are possibly produced in limited quantities.
This study covers the period-from Ground 25X1D
photography of revealed cons-ruc on activity in the phosphate
rock storage area. By he major production facilities were com-
pleted in the phosphate fertilizer area, the sulfuric acid area, the possible 25X1D
insecticide area, and the probable elemental phosphorus production area.
Between and support facilities were added in all the
areas. The plant was o serve In operation on photography of and
on all subsequent photographic coverage.
This report includes a photograph and a detailed line drawing of the
plant and a chronological summary of construction and operational status.

The Nan-ching Phosphorous Fertilizer Plant
is
located along the Yangtze
River, approximately II nautical miles north of the
Kiangsu Province (see Figure I). It is adjacent to
center of Nan-ching,
the Nan-ching Chemical
Plant Yung-li Chemical Industry
by the Nan-ching Heat and Power an
Electric power is provided 25X1A
a-chang-chen 25X1A
The plant occupies an area approximately 2,300 feet square
which
con-
tains about 120 acres (see Figures 2
and 3). It is served by a
rail
spur
from the Nan-ching to Chu-hsien rail
line. A controlled-access
road
enters
the northwest corner of the plant. A main wharf and two auxiliary wharves
on the Yangtze River serve the plant.
The primary function of the plant is the production of superphosphate
and probably triple superphosphate fertilizers. Secondary products include
sulfuric acid, and probably phosphoric acid and calcium sulfate (gypsum). A
limited quantity of elemental phosphorus is probably produced. Also, phosphorus-
based compounds such as insecticides are possibly produced in limited quantities.
The production flow at the plant is shown in Figure 4.
25X1 D
Ground photography shows that the storage facility in the phosphate rock
storage area was under construction in The first overhead 25X1D
photography of the plant in s ows a the major facilities in the
plant were completed and operational. Between
minor support buildings were constructed. The c rono ogy of construction is
shown in Figure 3.
The plant was observed in operation on photography of and on 25X1D
all subsequent photography as evidenced by emissions of smoke, acid mist, and
vapors, and by the variation in the number of rail cars and barges.
