petrochemiai
Petrochemiai (petrochemicals) are chemical products derived from petroleum and natural gas. The field, sometimes called petrochemistry, covers the transformation of hydrocarbon feedstocks into basic chemicals, intermediates, polymers, and finished materials used across modern industry.
Core processing routes include steam cracking of naphtha or gas oil to yield ethylene and propylene; catalytic
Major product groups include olefins (ethylene, propylene, butadiene), aromatics (benzene, toluene, xylenes), oxygenates (methanol, ethylene oxide
Industry structure: large complexes are frequently integrated with refining and gas processing, enabling shared feedstocks, energy,
Environmental and economic considerations: the petrochemical industry is energy-intensive and associated with greenhouse gas emissions and
