Title: Innovations by Robert A. Lengemann
Introduction
Robert A. Lengemann is a notable inventor based in Arlington Heights, IL (US). He has made significant contributions to the field of fluid catalytic cracking, holding a total of 3 patents. His work focuses on improving processes within the petrochemical industry, particularly in enhancing the efficiency and effectiveness of catalytic cracking units.
Latest Patents
One of his latest patents is the "FCC process with dual function catalyst cooling." This invention provides a unique arrangement for an FCC reactor and regenerator, allowing for independent control of temperature on both sides of the process. The design enables the withdrawal of cooled regenerated catalyst for transfer to a reactor riser, as well as cooled regenerator catalyst for return to the regeneration zone. This process can operate with a single cooler that supplies catalyst to both the reaction and regeneration sides.
Another significant patent is the "Method for reducing the temperature in a regeneration zone of a fluid." This method allows for the operation of a fluid catalytic cracking unit with a reduced temperature in the regeneration zone while processing hydrocarbon feedstock. It involves contacting the feedstock in a reaction zone with a mixture of regenerated fluidizable cracking catalyst and low coke make solid particles. This innovative approach maintains a lower temperature in the regeneration zone without affecting the reaction zone's operation.
