Title: J Francis Steadman: Innovator in Spent Acid Purification
Introduction
J Francis Steadman is a notable inventor based in Orangeburg, SC (US). He has made significant contributions to the field of chemical engineering, particularly in the purification of spent acids. His innovative approach has led to the development of a patented process that addresses environmental concerns associated with spent acid disposal.
Latest Patents
Steadman holds a patent for a spent acid purification process. This process involves removing contaminants from spent nitric-sulfuric nitration acid by mixing it with urea and heating it to temperatures between 75°C and 150°C. The off-gas produced from this reaction is treated with a catalyst containing metals from Groups IB, VB, VIB, or VIII to decompose nitrous oxides. The treated off-gas is then absorbed by spent acid, denitrated spent acid, or fresh sulfuric acid, optionally in the presence of air, to effectively absorb oxides of nitrogen. The spent acid scrubbing fluid undergoes the same process for contaminant removal.
