Dynamic Engineering (DEI) has formed a strategic alliance with Polycrystalline Silicon Technology (PST). DEI now offers PST’s advanced hydrochlorination technology as well as its fully closed-loop chlorosilane and silane technology.

Prior to this agreement, the majority of DEI’s TCS reactor licenses were based on chlorination technology. While both technologies are broadly used in the polysilicon industry, in some cases hydrochlorination can offer lower capital investment and operating costs due to the more efficient chemical conversion of STC versus thermal conversion.

“By creating an alliance between PST and DEI, we have effectively given the polysilicon market the best of either chlorosilane or hydrochlorination solutions for poly production,” said Kevin Drumm, vice president of business development at DEI.

“The full plant integration by DEI and PST provides for the optimization of state-of-the-art polysilicon plant design to minimize installed costs, maximize yields and minimize waste streams,” said Leo Rogers, president of PST.

“Dynamic Engineering has a 25-year history of bringing the most-effective processes to leading chemical companies and is pleased to join with PST’s 45 year history of polysilicon experience. With the combined DEI and PST experience and technologies, we anticipate accelerated growth in both existing and adjacent market segments over the coming years. At this time, we are also exploring synergistic technologies that can bring further process improvements to the polysilicon industry while minimizing capital investment,” remarked Joseph Ausikaitis, president/CEO of DEI.
