8. Hydrogen (H₂)
Hydrogen is a lightweight, non-toxic gas used in hydrogenation processes for producing various chemical compounds. It is also involved in petroleum refining, and the production of methanol and ammonia, and serves as a raw material in many chemical processes.
9. Chlorine (Cl₂)
Chlorine is a toxic, yellow-green gas used in the petrochemical industry for producing PVC (polyvinyl chloride) and disinfectants. It is also applied in producing hydrochloric acid and other chemical compounds.
10. Carbon Dioxide (CO₂)
Carbon dioxide is a colorless, odorless, non-flammable gas used in the petrochemical industry as a raw material for producing urea for agriculture, extracting natural gas, and other chemical processes.
Conclusion:
Petrochemical gases play a crucial role in producing various chemical products. These gases are used in processes like manufacturing plastics, fertilizers, synthetic rubber, and pharmaceuticals. Efficient utilization of these resources can lead to economic growth and higher productivity in the petrochemical industry.
