Key production processes

  1. GAS PROCESSING
  2. GAS FRACTIONATION
  3. CRACKING
  4. POLYMERISATION
  5. POLYMERS AROUND US

GAS PROCESSING

Associated petroleum gas (APG)

is obtained in the process of oil extraction. At a gas processing facility, it is separated into dry gas, NGLs
and SGN (stable natural gasoline that is used in further petrochemical processing).

Natural gas liquids (NGLs)

are a mixture of gases used as the main feedstock
for polymer production.

Alternatively, APG may be flared,
which is not environmentally friendly

GAS FRACTIONATION

Natural gas liquids (NGLs)

at this stage are separated into individual hydrocarbons and their mixtures: propane, butane and isobutane.

Liquefied petroleum gases (LPGs)

are considerably intended for further processing, with some of them also used for heating and as motor fuel.

CRACKING

Liquefied petroleum gases (LPGs)

are exposed to high-temperature. As a result of this cracking process, parent elements are transformed
into substances with new properties called monomers.

Ethylene, propylene and benzene

generated from cracking are the main feedstock
for polymer production.

POLYMERISATION

Monomer molecules

at this stage are combined in a chain to form a polymer.

Polyethylene, polypropylene, polyvinyl chloride and polystyrene

are basic polymers processed into end products using various methods.

POLYMERS AROUND US

Polymeric materials

are irreplaceable today. Light, strong, heat-resistant and easy to process, they are widely used in the production
of cars, home appliances, packaging, furniture, clothing and other goods.
