Process Technology International, Inc. (PTI) is pleased to announce the successful start-up and commissioning of PTI's patented JetBOx^TM Technology at the following facilities in the US.

The systems are described as follows:

Two (2) JetBOx Systems consisting of four (4) JetBOxes^TM each were installed on the twin shell 160 ton EAF at IPSCO Steel Alabama. Each JetBOx^TM will have the capability of injecting 1500 scfm of supersonic oxygen as well as carbon for slag foaming.

The JetBOx^TM system at CMC Steel, Seguin, Texas, replaced an existing combustion system on their 125 ton AC EAF and includes three (3) JetBOxes^TM for introduction and control of chemical energy. Each JetBOx^TM can deliver 1500 scfm of supersonic oxygen to the steel bath as well as carbon for slag foaming.

Each of these systems includes multiple JetBOxes^TM capable of introducing shrouded supersonic oxygen and injected carbon, flow control train, and integrated automation and control systems.

The ability of the JetBOx^TM injectors to operate submerged in the foamy slag layer significantly improves the efficiency of oxygen, carbon and natural gas inputs and helps reduce energy losses to the furnace off gas and sidewalls. Natural gas for oxygen jet shrouding can also be reduced due to the close proximity to the metal bath.

PTI's JetBOx^TM technology has now been adopted by over 60 steel plants in 18 countries with more than 250 JetBOxes^TM in operation.
