STC to TCS Conversion
KMPS’ process technologies convert silicon tetrachloride (STC) to trichlorosilane (TCS) and purify it to industry or PV grade TCS with > 100% yield based on inlet weight of STC. The electrical consumption is less than 0.25 kW/kg of STC processed.
Low Energy Purification Techniques
Our designs incorporate low energy membrane and crystallization processes to remove impurities from TCS, which reduce energy demand and produce a purer product that is less susceptible to impurity spikes.
KMPS designed and supplied all process modules of a commercial silane plant in 2012 that was successfully commissioned in 2013. The system converts metallurgical grade silicon into trichlorosilane . The trichlorosilane is then redistributed and purified to silane.
KMPS is actively pursuing projects to alleviate the STC accumulation problem, particularly prevalent in China. These projects focus on the hydrogenation of the surplus STC with MGS and hydrogen to produce TCS. The operating cost of these recovery systems, including depreciation, is less than the raw material cost for making TCS from purchased MGS, chlorine, and hydrogen.
