Title: Innovations of Norman F Hessler

Introduction

Norman F Hessler is a notable inventor based in Wheeling, IL (US). He has made significant contributions to the field of hydrocarbon conversion processes. With a total of 2 patents, his work has advanced the efficiency and effectiveness of thermal processing in the oil industry.

Latest Patents

Hessler's latest patents include an integrated thermal cracking and visbreaking process. This innovative process involves thermally processing two different heavy oil feed streams. A vacuum gas oil is charged to a thermal cracking zone, while a reduced crude fraction is directed to a visbreaking heater. The effluent from each thermal operation is separated into vapor and liquid fractions, with the vapor fractions being fed to a product fractionator. The liquid fractions enter separate but interconnected subatmospheric pressure separation zones, including a vacuum column. Additionally, the bottoms of a product fractionator and distillate from the vacuum column are charged back to the thermal cracking zone.

Another significant patent by Hessler is the integrated heat exchange on crude oil and vacuum columns. This method reduces the heat input required for the sequential fractionation of crude oil in both a crude column and a vacuum column. The desalted crude oil is flashed, and the flash zone liquid is split into two streams. Each stream undergoes a series of heat exchanges before being recombined, heated, and passed into the crude column.
