摘　　要：在西门子法多晶硅生产中,降低精馏能耗和提高精馏产品质量的方向主要是优化的工艺流程和高效的分离技术。通过应用预热进料、优化塔组排列顺序、差压热耦合精馏技术及高效规整填料等方法。Process optimization and efficient separation technology are the main direction of reducing en- ergy consumption and improving distillation product quality in Siemens poly-silicon production. By pre- heating the feed material, optimizing the order of the tower column group, employing differential thermal coupling distillation technology and efficient packing column methods and others, the operational stability and product quality is improved, and the energy consumption is reduced.
