ETHYLENE PROPYLENE PROPANE MIXED-C4 HYDROGEN PYROLYSIS GASOLINE

PROPYLENE

Propylene is produced through the cracking of hydrocarbons (naphtha, ethane, LPG, Gasoil, etc.)
such as petroleum or natural gas, and then the fractionation and purification with the difference
in boiling points of ethylene and mixed C4 Raffinate.
It is an olefinic hydrocarbon containing 3 carbon atoms and a colorless gas lighter than
air at the ambient temperature and pressure.

CAS number : 115-07-1 / Molecular formula : C3H6

Plant processes

This plant cracking naphtha with steam into the light hydrocarbon compound at a high temperature in excess of 800℃, and quenches, compresses and fractionate it to produce ethylene, propylene, mixed C4, pyrolysis gasoline (PG), etc.

  • Cracking Heater Unit
    This unit cracking naphtha with steam in a cracking furnace into the hydrocarbon compound with less carbon at a high temperature in excess of 800℃, produces high-pressure steam with the heat of the high-temperature cracked gas and sends it to the quenching unit.
  • Quenching Unit
    This unit cools down the high-temperature cracked gas from the cracking furnace with quench oil, fractionates heavy fuel oil (PFO, PGO), and cools it down with quench water. the quenched substance is sent to the compression unit.
  • Compression Unit
    To economically fractionate and refine the quenched cracked gas, this unit uses the compressor to raise the pressure to about 38 kg/㎠G.
  • Fractionation Unit
    This unit cools down the gas compressed by high pressure at a super-low temperature (-165℃), and uses the differences in boiling points to fractionate hydrogen, ethylene , propylene , propane, mixed C4 and pyrolysis gasoline (PG), etc.
Product uses

Utilized as the raw material for various derivatives of synthetic resins as well as Polypropylene(pp).

  • Polypropylene(PP)
