Rajesh Rajappan is a notable inventor based in Buffalo Grove, IL (US). He has made significant contributions to the field of hydrocarbon separation, holding 2 patents that showcase his innovative approaches to complex chemical processes.

Latest Patents

Rajesh's latest patents include "Processes and apparatuses for separating aromatic and non-aromatic hydrocarbons" and "Process and apparatus for controlling anti-foam injection using a differential pressure transmitter." The first patent describes a method where a solvent is mixed with aromatic and non-aromatic hydrocarbons. A first separation column is utilized to separate non-aromatic hydrocarbons from the solvent and the aromatic hydrocarbons. A second separation column further separates the aromatic hydrocarbons and the solvent. Additionally, a side draw stream from the second separation column is employed to heat the feed stream to the first separation column, while a bottom stream from the second separation column may be used to heat the liquid in the first separation column. A stab-in reboiler is also mentioned as a means to transfer heat from the bottoms stream to the liquid in the first separation column. The second patent focuses on controlling antifoam injection based on the pressure differential of an aromatics extraction unit using an intelligent differential pressure transmitter. This innovative controller communicates with the antifoam injection system to ensure that antifoam is injected only when necessary.
