Pipeline construction area from the boundary of GTL complex to the SGCC expansion area is located in the Guzar district of Kashkadarya region in the Republic of Uzbekistan. Geographically located 60 km to the south-west of Karshi city.
The project provides for the construction of pipelines for supplying naphtha, propane-butane mixture,
Shurtan Gas Chemical Complex (SGCC) as its main product uses natural gas resources for separation of ethane and producing 140 kt/a of ethylene, which is then converted to production of up to 125 kt/a of linear low density polyethylene.
Future evaluation of natural gas revealed increase in ethane concentration of up to 60%, which can be further processed to produce an additional 80 kt/a of ethylene. Therefore the project provides for the expansion of SGCC.
Naphtha is transported via naphtha pipeline from the GTL plant to the SGCC in the amount of 430 kt/a, with further processing in cracking unit to produce 285 kt/a of ethylene and 100 kt/a of propylene.
New bimodal polyethylene and polypropylene unit will be installed at SGCC to produce an additional 280 kt/a of HDPE product and 100 kt/a of polypropylene product in order to use excess amount of ethylene and propylene.
New
Imported fuel gas entering the complex will be used as fuel gas for the initial start-up until the gas separation unit and ethylene/naphtha cracking unit are brought back on-line. Fuel gas supply is then will be switched to the hydrogen-rich offgas from the naphtha cracker and make-up natural gas.
The project provides for the following pipeline technical data:
- Naphtha pipeline — 6″
- Nitrogen pipeline — 8″
- High pressure steam pipeline — 14″
- Hexene pipeline — 4″
- Propane-butane fractions pipeline (PBF) — 3″
- Steam condensate return pipeline — 8″
- Industrial waste pipeline — 6″
Project also provides for the installation of propane-butane fraction metering station and linear/block valve stations.
