Title: Hugh Lavery - Innovator in Flotation Deinking Process
Introduction
Hugh Lavery is a notable inventor based in Pennington, NJ (US). He has made significant contributions to the field of pulp and paper processing, particularly through his innovative flotation deinking process. His work focuses on improving the efficiency of ink removal from pulp fiber slurries, which is crucial for recycling paper products.
Latest Patents
Hugh Lavery holds one patent for his flotation deinking process. This patent describes a method for removing inks from a pulp fiber slurry using a combination of three key components. The first component is a polyester obtained through the reaction of di and/or tricarboxylic acids and/or their anhydrides with a polyalkylene glycol or one or more alkylene oxides. The second component is a first deinking agent, which is an alkoxylated hydrophobic base, such as an alcohol, amine, acid, or dimer acid. The third component is a second deinking agent, which is another alkoxylated hydrophobic base with a cloud point that is 2 to 20 degrees lower than that of the first deinking agent. This innovative combination allows for an improved foam profile, enabling longer continuous operation and reducing total chemical demand, optical bleach demand, and stickies.
