Title: The Innovative Contributions of Donald H. Renfro
Introduction
Donald H. Renfro is a notable inventor based in Bartlesville, OK (US). He has made significant contributions to the field of chemical engineering, particularly in the area of alkylation processes. His work focuses on improving the efficiency and accuracy of on-line analysis in industrial applications.
Latest Patents
Renfro holds a patent for a method titled "On-line analysis of acid catalyst in an alkylation process." This innovative approach involves a computer-implemented method for the on-line determination of concentrations in an HF alkylation process catalyst stream. The catalyst stream contains HF acid, ASO, water, and optionally an additive that suppresses the vapor pressure of HF acid. The method utilizes near-infrared spectroscopy coupled with chemometric data analysis. Specifically, it employs a partial least squares regression technique to determine unknown concentrations based on spectral calibration data. In practice, an absorbance spectrum of the material is obtained from a slipstream taken from the process alkylation catalyst stream. The detected spectrum is then mathematically analyzed with the aid of a computer to simultaneously predict the concentrations of HF acid, ASO, water, and the optional additive.
