Title: Innovations of James R. Sweet

Introduction

James R. Sweet is a notable inventor based in Clearwater, California. He has made significant contributions to the field of engineering, particularly through his innovative patents. With a total of 3 patents to his name, Sweet has focused on processes that enhance the efficiency and quality of chemical production.

Latest Patents

One of his latest patents is the "Membrane process for increasing conversion of catalytic cracking." This process improves the yield and quality of products obtained from cracking units by subjecting the product stream to a selective aromatics removal process. The recovered aromatics lean stream is then recycled back to the cracking unit, allowing for increased conversion to higher-value products.

Another significant patent is the "Membrane assisted settling process." This method separates mixtures into two fractions using a combination of settling, ultrafiltration, and permeate/retentate recycling. The process allows a multi-component feed stream to separate into two major phases, with an intermediate zone where the concentration of components is relatively equal. A slip stream is drawn from this zone and processed through a membrane separation unit, resulting in two recovered streams: a bottoms stream rich in one component and a top stream rich in another.
