Title: Innovations of Francisco Jose Freire
Introduction
Francisco Jose Freire is a notable inventor based in Wilmington, DE (US). He has made significant contributions to the field of chemical engineering, particularly in the production of isocyanates. With a total of 7 patents to his name, Freire's work has had a substantial impact on the industry.
Latest Patents
One of Freire's latest patents is focused on the production of isocyanate using chlorine recycle. This innovative process and system not only produce isocyanate but also convert anhydrous hydrogen chloride, a by-product of isocyanate production, into chlorine gas through an electrochemical cell. The chlorine is then recycled back into the isocyanate production process. This method effectively reduces the cost of producing isocyanate while minimizing the disposal issues associated with anhydrous hydrogen chloride by transforming it into a valuable starting material.
Another significant patent by Freire involves an electrochemical cell with split fluid and current feed. This invention allows for the cathode or anode inlet and outlet fluid to be fed from both ends of the electrolyzer, rather than just one. Additionally, the current can be fed to the anode or cathode side at one point and removed from the opposite end at two points. This design reduces internal shunt current and increases the active area of the electrolyzer without expanding the overall area of the current distributors. Consequently, the voltage required by the electrolyzer can be halved, enhancing efficiency.
Career Highlights
