Propylene

From GAWDAwiki

Propylene is a fuel gas. It is a member of the olefins family made of a hydrocarbon molecule comprising three carbon atoms and six hydrogen atoms, C₃H₆. Two of the carbon atoms form a double covalent bond in which two pairs of electrons are shared. ^[1]

The propylene molecule is produced as a co-product of ethylene production through the steam cracking of ethane to naphtha and gas oils. Propylene is also produced as a by-product of petroleum refining.

The main use of propylene is as a monomer, mostly for the production of polypropylene. Propylene is used mainly to produce plastics for injection molding and fibers. Propylene is also used as a fuel gas for various heating and cutting processes. It has a similar calorific value to propane, but it has a higher flame temperature. Polymer-grade Propylene is the most dominant fuel gas used in the U.S metal working market.

Propylene High vapor pressure required 4BW260 cylinder (33.2 psi @ 0 F., 67 psi @ 30 F. Excellent economics for fabricating industry.^[2]
