Petrochemicals and gas conversion

Adsorbtion is widely used in raw materials treatment processes for petrochemical and gas processing productions.

Adsorbents of Salavat Catalyst Plant are highly effective in dehydration and purification of operating enviroments disposed to separation and polymerization: pyrolysis gas, ethan-ethylene fraction, propane-propylene fraction and others. The using of Salavat Catalyst Plant aluminium oxide sorbents and modified mole sieves allows to obtain high quality final products during process of demercaptanisation of carbon hydrate liquid fluides, natural gas liquides, liquefied hydrocarbon gases and others.

Adsorption method allows to solve the following tasks:

  • Dehydration of saturated hydrocarbon spreads;
  • Dehydration of unsaturated hydrocarbon spreads;
  • Dehydration of isomerization and catalytic reforming gases (HBG, CO2, Nitrogen);
  • Dehydration of pyrolized species (pyrolysis gas, propane-propylene fraction, butane-butylene fraction, ethan-ethylene fraction);
  • Dehydration of catalytic cracking gas;
  • Purification of unsaturated hydrocarbon spreads from polar compounds;
  • Purification of unsaturated hydrocarbon spreads from sulfur containing compounds (H2S, COS, RSH);
  • Purification of unsaturated hydrocarbon spreads from oxygenate and sulfur containing compounds;
  • Dehydration and purification of liquid hydrocarbones.
