Title: Innovations by Richard P. DeFilippi

Introduction

Richard P. DeFilippi is an accomplished inventor based in Cambridge, MA. He has made significant contributions to the field of chemical engineering, particularly in the area of separating organic liquid solutes from their solvent mixtures. With a total of 2 patents to his name, his work has the potential to revolutionize conventional distillation techniques.

Latest Patents

DeFilippi's latest patents include an "Apparatus for separating organic liquid solutes from their solvent" and a "Process for separating organic liquid solutes from their solvent mixtures." Both patents describe a method where a mixture is contacted with a fluid extractant at specific temperature and pressure conditions. This allows the extractant to act as a solvent for the solute but not for the solvent. The resulting fluid extract is then depressurized to produce a still feed, which is distilled to form still overhead vapors and liquid still bottoms. The enthalpy required for this distillation is generated by compressing the still overhead vapors, which indirectly heats the still feed. This innovative process is particularly effective for separating mixtures that form azeotropes, such as oxygenated hydrocarbon/water mixtures, and requires significantly less energy than traditional distillation methods.
