2.2 Akchalak Gas Chemical Complex
Akchalak gas-chemical complex will be located on the territory of the Republic of
Karakalpakstan Kungrad district, 3 km north-east of the residential village Akchalak and
projected residential village MCC.
Processing facilities are located in the area of 72 hectares. In the area of construction
of MCC are high-voltage power lines 35 and 110 kV, the main gas pipeline Central Asia - a
compressor station Akchalak, road and railway Kungrad - Beineu, located Kungradskiy
soda factory, railway station Kyrkkiz with oil loading rack, open GCF Akchalak,
Kokchalak, Karachalak, West Barsakelmes that make up the UAE Ustyurtgaz "AK"
Uzneftegazdobycha "Uzbekneftegaz.
Raw materials for MCK Akchalak is natural gas condensate field Surgil. The average
for the field potential content (g/m3) in the formation gas is methane homologues: ethane
(C2) - 54.0; propane (C3) - 36,3; i butane (C4) - 8,33; n butane (C4 ) - 9.67; fractions C3 +
C4 - 54.33; C5 + higher - 44.24.
Natural gas deposits Surgil carbonate hydrocarbon, light hydrocarbon composition of
low-(moln.) of carbon dioxide - 0.79% and nitrogen - 1,12%, hydrogen sulfide is not
detected. The methane content - 90,2%.
As a result of gas processing trade get dehydrated natural gas. In the following
extract ethane from the gas for the production of polyethylene, propane and butane to
produce liquefied natural gas (PBF) and gas condensate - the raw material for production of
motor fuels in refineries.
In the production-based MCC is the process of extraction of natural gas of ethane,
ethylene production from him and further processing of ethylene in polyethylene, which has
wide application in the national economy. The project provides a set of clock work over
8000 hours per year, and reserve time for the annual preventive maintenance (similar
SHGHK).
In the production processes at the site Akchalak MCC presents different types of
equipment, chemical equipment, process piping, high pressure at high and subzero
temperatures. This - the vertical turrets (distillation columns, hardening, saturatornye
columns, etc.), reactors, absorbers, strippers, converters, absorbers, various tanks,
separators, filters, heat exchangers, tube furnaces, boilers, compressors, pumps, tanks and
gas tanks for the storage of products and used chemicals, flare system, etc.
All equipment and materials for construction Akchalak GCC foreign complete
delivery, ie have a high technical level. However, the production of this scale still can not do
without the allocation and release of harmful substances into the atmosphere, as well as
liquid and solid wastes.
A distinctive feature of these chemical plants is to use both low and high
temperatures in industrial processes, including at high pressures.
To ensure a higher level wastelessness most combustible emissions (exhaust gases,
liquid products vat of devices, etc..) Handled in a special fuel system and go to the burning
