Title: The Innovations of Franz Schreieder
Introduction
Franz Schreieder is a notable inventor based in Tann, Germany. He has made significant contributions to the field of chemical engineering, particularly in the area of distillation and polysilicon production. With a total of five patents to his name, Schreieder's work has had a considerable impact on industrial processes.
Latest Patents
One of his latest patents is a method and apparatus for the separation by distillation of a three- or multi-component mixture. This innovative method involves feeding a mixture of three or more components into a first distillation column, where the high boiler is removed as a bottom fraction. The top fraction is then fed into a second distillation column, allowing for the removal of medium and low boilers through sidestream takeoff and top fraction removal, respectively. The reflux from the second column is fed back into the first column, optimizing the separation process.
Another significant patent is for dust-free and pore-free, high-purity granulated polysilicon. This invention produces polycrystalline granulated silicon with a density exceeding 99.9% of the theoretical solid density. The resulting particles have a pore content of less than 0.1% and a surface roughness of less than 150 nm, making them ideal for various high-tech applications.
