Title: Curt Schneider: Innovator in Maleic Anhydride Recovery
Introduction
Curt Schneider is a notable inventor based in Kirchheim, Germany. He has made significant contributions to the field of chemical engineering, particularly in the recovery of maleic anhydride. His innovative approach has implications for both efficiency and environmental sustainability in chemical production.
Latest Patents
Curt Schneider holds a patent for a method of recovering maleic anhydride from the effluent produced during the manufacturing of phthalic anhydride. The process involves evaporating the effluent at temperatures ranging from 40°C to 150°C and pressures between 50 to 760 mm, reducing the water content to less than 10% by weight. The concentrate is then heated in a thin-film or falling-film evaporator at pressures from 100 to 600 mm and temperatures between 120°C to 180°C, followed by distillation in a column. The pure maleic anhydride is extracted laterally, while the aqueous condensate is recycled to the offgas scrubber. This innovative method not only enhances recovery rates but also minimizes waste.
