Title: Thomas A Vivian: Innovator in Metal Recovery and Stripping Compositions
Introduction
Thomas A Vivian is a notable inventor based in Midland, MI (US), recognized for his contributions to the field of metal recovery and environmentally friendly stripping compositions. With a total of 7 patents to his name, Vivian has made significant strides in developing innovative processes that enhance efficiency and sustainability in industrial applications.
Latest Patents
One of Vivian's latest patents focuses on a process for separating and recovering metal values from a waste stream. This method involves providing an aqueous waste stream containing metal values, including chromium, and subjecting it to an oxidation process to convert chromium (III) to chromium (VI). The process further includes adjusting the pH of the stream to precipitate other metal values and separately recovering chromium (VI) from the remaining metal values. This innovative approach is particularly relevant for waste streams from electroplating or electroless processes, where metals such as iron, cobalt, zinc, cadmium, nickel, copper, silver, aluminum, and chromium are present.
Another significant patent involves a composition for stripping paint and varnish from substrates. This composition combines conventional industrial chlorinated solvents, such as methylene chloride, with a wax, like paraffin wax. The addition of a novel class of evaporation retarding chemicals enhances the effectiveness of the stripping action while improving environmental safety by reducing the concentration of methylene chloride in the surrounding atmosphere.
