公司采用硅氢氯化法生产三氯氢硅,自主设计并成功建设国内第一套成规模的“三氯氢硅加压合成系统”,改变国内三氯氢硅合成采用常压法合成工艺,自主设计三氯氢硅反应沸腾床,使三氯氢硅转化率处于行业领先水平。原料消耗及能耗指标相对较低,生产过程中的副产品可循环利用,具有清洁生产环境友好的特点。公司在传统的工艺基础上不断进行完善,目前已基本实现了物料的闭路循环,提高了三氯氢硅的转化率及设备运行的安全性。

   We use “silicon - hydrogen chloride” method to produce trichlorosilane and has constructed the first set of large-scale “trichlorosilane synthesis pressurization system” in China by independent design, which changed the atmospheric synthesis process commonly used. We have also independently designed trichlorosilane boiling bed reactor, putting trichlorosilane conversion rate ahead of industry-leading level. The low consumption of raw materials and energy makes it available to recycle the byproducts generated in production process, which is clean and environment-friendly. We have continuously improved the traditional production process so that closed cycle of materials has been basically achieved, which improves the conversion rate of trichlorosilane and the safety of equipment.
