Interview with Bill Stry of Harper International

Ahead of his presentation at GOCarbonFibre 2017 we spoke to Bill Stry, Process Technology Lead at Harper International, about distinguishing features of a carbonisation line designed for heavy tows, why this is an important topic to discuss, what effect it could have on the industry and more.

Q1. Your presentation looks at distinguishing features of a carbonisation line designed for heavy tows, can you briefly explain what it will be covering? 

Compared to 12K lines, heavy tow lines have higher instantaneous throughput. This requires more heating power, more air and nitrogen velocity, and efficient methods of purging and cooling. It also means higher rates of exhaust bi-products that must be continously abated. Another aspect of heavy tows is greater catenary that creates specific design challenges for thermal equipment. Also, heavy tow precursor packages tend to have shorter run times, so achieving rapid feedstock turnover is essential for economic production. 

Q2. Why is this an important topic to discuss, and what effect could it have on the industry?

There are a number of applications for heavy tows that are forecast to have growth in demand, including ground and marine transportation, wind energy, and infrastructure. Expanded heavy tow capacity and lowering costs will be critical factors in achieving the more optimistic features.

Q3. What are you most looking forward to at the GOCarbonFibre 2017 conference?

The Tuesday workshop should be informative and maybe even lively. It is always interesting to me to gather with a group of peers and see what people are up to. 

Bill will be presenting as part of the Emerging Technologies and New Developments session at the conference. Other speakers in the session include Suragus, Michelman, Astris Carbon and SGL Group.
