WUCHING CHEMICAL FERTILIZER PLANT
SHANG-HAI, CHINA
A nitrogenous fertilizer plant is located in an industrial chemical
complex in the southern outskirts of Shang-hai. This installation is
situated on the west bank of the Huang-p'u River approximately five
nautical miles south of Lung-hua Airfield at 31 O4N - 121 28E.
The identification of major processing units and an analysis of
changes within the installation since 1963 are included within this
report, which is based on interpretation of overflight photography
obtained between The following descriptions
are keyed to annotations on Figure .
1. Gas Production Section
Gas to be used in the synthesis of ammonia is produced
in five probable water gas retorts (Item a). Coke, the major raw
material, is conveyed to the retorts from the coke chemicals plant,
directly north of this installation. Sulphur compounds and other
impurities are removed in the purification units (Item b) and
hydrogen enrichment occurs in the probable contact ovens (Item c).
Three gas retorts appear complete on photography,
and construction was in progress on two additional retorts which
were completed by The adjacent gas processing
facilities in thi n were a so expanded during this period.
No additional construction was in progress in
2. Ammonia Production Section
Ammonia is synthesized in this section in the tall converter
towers attached to the large compressor building (Item d). The
0 and an expansion of these facilities was in progress at
that time. By I this construction, which included an
addition to the compressor building, a second converter tower, and
above ground pipelines connecting the new facilities, was nearing
completion. These new facilities, which may approximately double
the previous ammonia producing capacity, appear to be complete by
and no new construction was in progress.
3. Sulfuric Acid Section
Sulfuric acid is produced in the converter and tower units
(Item e) from sulphur dioxide generated in the roaster building
(Item f). The sulphur source is a sulfide ore, probably pyrite, which

is stored and processed in the large conveyor served buildings
(Item g). The production facilities of this section were complete
and operating in Changes between this date and
include construction on the sulfide ore processing
and storage area and on a conveyor served shipping area for the solid
residue from the roasting section. Construction was continuing, on
these support facilities in
4. Fertilizer Section
Sulfuric acid and ammonia, produced in the adjacent sections,
are used in the manufacture of ammonium sulfate fertilizer in this
area. The reactor building (Item h) is connected by conveyor to the
processing, packaging, and shipping building (Item i). Only very
minor changes have taken place in this area between
Two small tanks and one medium size tank are now
located on the river bank adjacent to the conveyor, where a small
building previously stood; and a small processing section, possibly
for the recovery of unreacted ammonia from the nearby urea. plant
(Section 5) has been built near the ammonium sulfate reactor
building. Both of these changes have occurred since
5. Urea Section
This large new section is for the production of urea. Carbon
dioxide is recovered and processed in the tower units (Item j),
immediately south of the ammonia synthesis section. Ammonia and
carbon dioxide are combined under controlled temperature and pressure
in special corrosion resistant reactors (Item k) to form ammonium
carbamate which decomposes into urea and water. The product is
dried and then conveyed to the final processing, packaging, and
shipping building (Item 1). The entire urea section was in the
early stages of construction in
excellent progress had been made, witti theT approximately 15%
complete. The urea ection appears to be in operation on coverage
6. An additional treatment pond has been built in this water
treatment section between
7. Administration and other support facilities for this
installation are located west of the above described production
facilities. During this same period of time, expansion was also
continuing in this area. Several shops and administration buildings
were erected.
Steam and power are supplied by the Shang-hai Thermal Power
Plant, Wuching, located a short distance south of this installation.

The major products of Wuching Chemical Plant are ammonium
sulfate and urea; produced from ammonia, carbon dioxide and sulfuric
acid, all of which are manufactured at this site. The first stage
development of this plant appeared to be well advanced by
and some progress was already evident on an expansion of the
gas generator facilities. By ammonia, sulfuric
acid, and ammonium sulfate were being produced. At this date, a
major addition to the ammonia synthesis section was in progress
and the urea section was in the early stages of construction. By
expansion of the ammonia synthesis section appeared
to be nearing completion and significant progress had been made on
the urea section. On photography from all production
sections of the plant appear to be in operation an he major
expansion of this plant, between 1963 and 1965, appears complete.
Only minor units are still under construction and significant new
expansion is not evident.
