Title: **L Graydon Carpenter: Innovator in Aluminum Chloride Processing**
Introduction
L Graydon Carpenter, an accomplished inventor based in Lower Burrell, Pennsylvania, has made significant contributions to the field of chemical engineering. With a focus on advancements related to aluminum chloride production, Carpenter holds two patents that showcase his innovative approach to environmental management and efficiency.
Latest Patents
Carpenter's latest patents reveal his expertise in treating offgas produced during aluminum chloride processing. One notable patent describes a comprehensive process for treating aluminum chloride production offgas, which contains various components such as Cl2, CO, CO2, HCl, COCl2, COS, SO2, N2, SiCl4, and metal chlorides. This innovative method utilizes water vapor in the presence of an alumina or low iron sand catalyst to convert SiCl4 and metal chlorides to their corresponding oxides and HCl. Additionally, the process involves the subsequent reaction of COCl2 with water vapor using an activated carbon catalyst, effectively producing CO2 and HCl, while removing HCl by contacting the offgas with liquid water.
Another significant invention of Carpenter's is the Fume Flare method, which focuses on the effective burning of fume, including combustible gases and gas-borne particles. This method involves moving fume through a tube with a blind end and slits, ensuring that the fume remains at ignition temperatures. The design of the tube, including the width and total area of the slits, is meticulously calculated to achieve optimal fume velocity that exceeds the flame velocity, enhancing combustion efficiency.
