Title: Innovations of John C. McIntyre
Introduction
John C. McIntyre is a notable inventor based in Hackettstown, NJ (US). He has made significant contributions to the field of chemical engineering, particularly in the recovery of valuable compounds from various mixtures. With a total of two patents to his name, McIntyre's work showcases his expertise and innovative thinking.
Latest Patents
One of McIntyre's latest patents is a process to recover benzene from mixed hydrocarbons by extractive distillation. This method involves separating benzene and other aromatics from a stream of mixed hydrocarbons using a solvent system that includes dimethyl sulfoxide and optionally a co-solvent, preferably water. The process is followed by distillation stripping of the aromatics from the enriched solvent system, allowing for the recycling of the lean solvent back to the extractive distillation step.
Another significant patent is a method for recovering carboxylic acids from aqueous solutions. This method focuses on acids with one to ten carbon atoms, particularly formic acid and acetic acid. The process involves contacting the aqueous solution with a solvent made of mixed trialkylphosphine oxides in a counter-current liquid-liquid extraction flow. This technique effectively transfers the acids from the aqueous solution to the solvent, producing a raffinate low in acid content and a rich solvent. The rich solvent is then dehydrated to separate water, and the acids are stripped from it, allowing for the lean solvent to be returned to the extraction step.
