Title: Innovations of Steven S. Lowenthal
Introduction
Steven S. Lowenthal is a notable inventor based in Flanders, NJ (US). He has made significant contributions to the field of chemical engineering, particularly in the area of refining processes. With a total of 4 patents to his name, Lowenthal's work has had a substantial impact on the industry.
Latest Patents
One of his latest patents is focused on the removal of nitrogen compounds from FCC distillate. This method involves using formaldehyde to selectively couple organic heterocyclic nitrogen species in the FCC feed or distillate. The resulting higher boiling coupling products fall outside the boiling range of FCC distillate, thereby improving the operation of subsequent hydrodesulfurization steps. This innovation is crucial for ensuring that the distillate fraction meets low sulfur standards. The formaldehyde is preferably utilized in the form of paraformaldehyde, and the reaction is conveniently conducted in the cycle oil pumparound circuit of the FCC main column.
Another significant patent by Lowenthal is a process for flexible vacuum gas oil conversion using divided wall fractionation. This invention describes a two-step process for the selective conversion of vacuum gas oil, which includes thermal conversion followed by catalytic cracking of the thermal conversion products. The conditions in both steps can be adjusted to vary the product slate, and the combined products are separated in a divided wall fractionator.
