RE: PROven coke technology


Hello again, Donna Lee.  Hope your recovery from surgery is going well.

I'm following up regarding your December 20 inquiry regarding "pressure regulated oven" (PROven) technology.  I sent your inquiry to USS and the other COETF member companies for review.

Based on the feedback I have received, the only known application of this technology in the US is on Battery C at USS-Clairton.  It was possible to construct Battery C with PROven technology because the technology was included as part of the original design prior to the battery starting up in November 2012.  The cost of the technology was included in the original battery construction cost; however, USS lacks any information regarding the itemized cost of the PROven technology separate from the other components of the battery.  All of the other USS-Clairton batteries were constructed before Battery C.

COETF members are not aware of any applications of PROven technology - either the original generation or the "next generation" of the technology described in the vendor's presentation materials you sent (attached) - to existing batteries in the US.  Hence, we have no information on the feasibility, efficacy, or cost of trying to retrofit PROven on existing coke ovens.

Contact me if you have additional questions.  Thanks, DCA

Subject: PROven coke technology

Hi David. Hope you are well and ready for a holiday. I had a question that I may have asked you before. I had received information about the PROven technology for coke ovens. It seems to regulate oven pressure and reduce emissions during charging. The company would not/could not provide costs nor emission reductions. I will be including this technology in the "technology review" memo for the coke RTR. The coke facility using this technology cited in the information provided by the company is US Steel Clairton (pg. 23 of the pdf attached). Can you inquire as to the costs and reductions, and why a facility would use the technology for only some batteries and not all? And also confirm that its benefit is only for charging.
