Social effect from the project implementation

Prerequisites for the creation of a Gas chemical complex based on MTO

  • The creation of the GCC opens the way for diversifying the economy — exporting not only gas but also finished chemical products with high added value.
  • Contribution to the country’s economy growth through tax payments — total amount of taxes for the entire project life (20 years) approximately equals to 2 bln USD.
  • GCC products can be a feedstock for adjoined industries.

Creation of more than 1,300 new vacancies

New specializations in universities and professional colleges

Environment for the revitalization of related sectors of the economy

Multiplicative effect

Scheme of production

start of production in 2024

Gas synthesis and methanol production unit (Syngas & MeOH)

Methanol unit (Syngas, MeOH) is designed for the production of raw methanol, one of the most important organic products in terms of value and scale of production, which, in particular, shall serve as the raw material for the olefin production unit. The GCC configuration includes the Haldor Topsoe’s licensed technology of methanol production by catalytic hydrogenation of carbon oxide and dioxide (synthesis gas).

start of production in 2024

Air Separation unit (ASU)

Air separation unit is designed for separation of atmospheric air into components, namely oxygen and nitrogen. The basis of the process is cryogenic rectification that results in the production of goods in gaseous or liquid form with a high degree of purity.

start of production in 2024

Low density polyethylene (LDPE) and Ethylene vinyl acetate (EVA) unit

LDPE and EVA are produced using gas phase polymerization technology, licensed by the Italian company Versalis. Capability to vary the physicochemical and rheological parameters of polyethylene using the high-pressure mode in a tubular reactor is the main advantage of the technology. This allows to get LDPE and EVA of various types in one processing line.

start of production in 2024

Monoethylene glycol (MEG) unit

Ethylene glycol is produced from ethylene through the oxidation of ethylene, using Scientific Design’s technology. Ethylene oxide reacts with water to form ethylene glycol.

start of production in 2024

MTO unit (methanol to olefins)

Methanol obtained at the MeOH unit is used as a feedstock for olefins productions at the MTO unit licensed by the Chinese company Sinopec TECH. The technology of converting methanol to olefins using a fluidization process via continuous regeneration reaction in a fluidized bed, is applied.

start of production in 2024

Polypropylene (PP) unit

The UNIPOL® PP process plant from Grace is notable for being easy to operate and maintain. The UNIPOL® PP, fully gas phase technology based on a reactor system with fluidized bed, is designed to have fewer moving parts and less equipment than any competing technology.

start of production in 2024
start of production in 2024

Polyethylene terephthalate (PET) unit

PET production is based on the patented INVISTA and UOP technology for continuous polymerization (CP) unit and solid state polycondensation (SSP) units, respectively.
