China began the production of superphosphate
and fused calcium-magnesium phosphate in 1950s. From 1960s,
a certain number of small-sized ammonium phosphate plants
and associated phosphoric acid plants had been built up in
succession, which mainly produced mono-ammonium phosphate.
Since 1980s, in order to accelerate the development of ammonium
phosphate, by introducing advanced western technology and
utilizing domestic technology, 15 large and medium-sized plants
producing high-concentration phosphate compound fertilizers
and more than 80 medium and small-sized ammonium phosphate
plants using slurry process and associated phosphoric acid
plants have been built up, forming a considerable scale. At
present, the total production capacity for ammonium phosphate
has been above 8.5 million tons, and the production capacity
for NPK has been approximately 9 million tons. In 2002, the
phosphate fertilizer output of China reached 8.06 million
tons (as 100% P2O5), which accounts for 24% of the phosphate
fertilizer output of the world and took the second position
in the world.
ECEC is one of the earliest engineering companies
engaged in developing technology and constructing projects
for phosphate compound fertilizer, and has in succession undertaken
the construction of dozens of large and medium-sized phosphate
compound fertilizer bases or plants. The variety of the products
includes SSP, MAP, DAP and NP/NPK. Examples of these bases
or plants include the phosphate compound fertilizer base of
Anhui Liuguo Chemical Industry Co., Ltd. for 200kt/a of phosphoric
acid (as 100% P2O5), 400kt/a of DAP
and 100kt/a of NPK; the phosphate compound fertilizer base
of Yunnan Honglin Chemical Industry Co., Ltd. for 160kt/a
of phosphoric acid (as 100% P2O5), 240kt/a
of DAP and 150kt/a of NPK; the plants of Fuling Chemical Industry
Co., Ltd. for 120kt/a of phosphoric acid (as 100% P2O5)
and 240kt/a of DAP; the 800MTPD DAP project of BCIC, Bangladesh;
the plants of Yunnan Phosphate Compound Fertilizer Base for
300kt/a of phosphoric acid (as 100% P2O5)
and 600kt/a of DAP; and the 600kt/a NPK plant of Sino-Arab
Fertilizers Co., Ltd., etc. With dozens of years' continuous
development of engineering technology and uninterrupted engineering
experiences, ECEC has been in the leading position in the
construction of phosphate compound fertilizer projects in
China.
In order to provide customers with phosphate
compound fertilizer plants that are advanced in technology
and reliable in operation, ECEC maintains long-term and good
cooperative relations with a wide range of well-known foreign
licensers, such as Rhone-Poulenc, Pryon, GP, Hydro, Incro,
etc. in addition to independently developing process technology
and proprietary equipment.
Sample projects:
240kt/a Di-Ammonium Phosphate Project
Customer: Anhui Liuguo Chemical Industry Co., Ltd.
Plant capacity: 120kt/a of phosphoric acid, 240kt/a of DAP
Source of technology: ECEC's process technology
Process route: Phosphoric acid is produced by the di-hydrate
process, double-tank reaction technology, which uses a tilting-disk
filter for filtration, forced circulating and vacuum concentration,
with which DAP is produced by a pre-neutralization, ammoniation
& granulation process and quality DAP product is obtained
through the process steps of neutralization, granulation,
drying, screening, crushing, cooling, off-gas scrubbing, etc.
ECEC's scope of work: Provision of process technology, engineering
design, technical service, supervision on construction, installation,
commissioning and start-up.
Construction time: 1999~2001.
Qinhuangdao 600kt/a NPK Compound Fertilizers
Project
Customer: Sino-Arab Chemical Fertilizers Co., Ltd.
Plant capacity: 600kt/a of NPK
Source of technology: License and process package from GP,
France.
Process route: Phosphoric acid, potassium salt, nitrogen salt
and ammonia are used as raw materials with a pipe-reactor
technology, which go through reaction and granulation, drying,
screening, crushing, cooling and off-gases scrubbing to get
high-quality NPK product.
ECEC's scope of work: Turnkey.
Construction time: 2000~2001. |
