Propylene FCC

General Characteristics
Propylene is manufactured by pyrolysis of oil fractions. It is a colourless, non-toxic, extremely combustible, easily inflammable gas.

CAS: 115-07-01

Propylene is used as a monomer for the production of polymers (polypropylene and its copolymers), intermediate product for the production of chemical substances (oxoalcohols, acrylic acid) and as a technical gas for welding, cutting, etc.

The product is classified as hazardous pursuant to Act No. 350/20011 Coll. and corresponding EU legal regulations (Regulation (EC) No 1272/2008 CLP, Directive No 67/548/EHS or Directive No 1999/45/EC.

Packaging, Storage, Transportation
Liquid propylene is stored in tightly closed tanks and is transported in railway tanks. Both the railway and storage tanks are made from low-temperature steel, cooled bellow propylene boiling point or pressurized.
