Description and Use

 

Petroflo 20Y14 is a blend of chain terminators designed to inhibit free radical polymerization fouling in petrochemical

and refinery processing equipment.
Petroflo 20Y14 is specifically designed for treatment of free radical polymerization

in the presence or absence of oxygen.
Petroflo 20Y14 is extremely effective in chlorinated hydrocarbon systems.

 

Application

 

Petroflo 20Y14 is far superior to Tertiary Butyl Catechol (TBC) in peroxide inhibition (see Figure below).

 

Therefore, Petroflo 20Y14 is excellent in stabilizing reactive product streams during storage or shipment (i.e., crude

butadiene feedstocks).

 


Free radical stabilization protection is comparable to the common amine antioxidants. Petroflo 20Y14 can be used in

place of amine antioxidants
 if final product color requires improvement.

 

Petroflo 20Y14 is extremely effective in chlorinated hydrocarbon streams where the strong amines cannot be used and

a hindered phenol is not as effective.

 

In a Gulf Coast chlorinated hydrocarbon facility, the hindered phenol was replaced with Petroflo 20Y14. The chemical

requirement of
 Petroflo 20Y14 was half of the demand for the hindered phenol.

 

Fouling apparatus test data confirms Petroflo 20Y14 is far more effective than phenolic chemistries in preventing fouling

of olefinic feedstocks under high temperature conditions. This product should be appropriate for use in columns, reboilers,

and preheat systems.
