GT Advanced Technologies - Hydrochlorination and TCS Purification Plants
Existing Designs Fast-Track Project and Reduce Expense. GT Advanced Technologies offers unrivaled industry-specific experience and technical resources for the design, construction, commissioning, start-up and operation of hydrochlorination and TCS purification production facilities. Operational experience and use analysis with over twenty hydrochlorination plants demonstrates a record of achievement in safety, quality and consistency. When plant owners and investors want to develop best-in-class hydro-chlorination and purification systems, GT Advanced Technologies is well qualified as their single-point contact for reliable integration. Existing optimized plant designs reduce capital expense, improving cost control and start-up.
Thermal Heating (ATH) System generates the optimal temperature within a hydrochlorination fluid bed reactor (FBR) by heating the process gas prior to FBR entry. The ATH system is extremely flexible and can be designed to easily integrate into a customer’s existing hydrochlorination operation helping to debottleneck the TCS production process or it can be designed to completely replace the existing electrical heaters in construction of a new hydrochlorination facility. GT’s ATH system incorporates several novel design enhancements of the vessel and internal components that offer a significant upgrade in reliability and on-line time over traditional in-line heaters.
After the hydrochlorination process generates TCS, resulting impurities such as boron, phosphorous, and metals are removed to the sub-part-per-billion impurity level in the TCS Purification Process, allowing for electronics grade TCS. GT Advanced Technologies’ Purification Process also converts >95 percent of the dichlorosilane (DCS) produced in the hydrochlorination process to TCS, which can be easily separated from the BCl3. Unreacted TCS is recycled into the process for purification, while the BCl3 and residual DCS are vented to maintain product quality.
