Title: Innovations of Carlos G. Casillas in Membrane Technology

Introduction

Carlos G. Casillas is a notable inventor based in San Jose, CA, who has made significant contributions to the field of membrane technology. With a total of 2 patents, his work focuses on innovative processes and materials that enhance the separation of hydrocarbons.

Latest Patents

One of his latest patents is the "Olefin separation membrane and process." This invention involves a membrane and process designed for separating unsaturated hydrocarbons from fluid mixtures. The unique aspect of this membrane is that both the feed and permeate streams can be dry, and it does not require water or solvent swelling. The membrane exhibits a selectivity for unsaturated hydrocarbons over saturated hydrocarbons with the same number of carbon atoms, achieving a pressure-normalized flux of at least about 5 × 10⁻⁶ cm³ (STP)/cm²·s·cmHg. This performance is measured in a substantially dry environment.

Another significant patent is the "Process for restoring membrane permeation properties." This process aims to restore the selectivity of high-free-volume, glassy polymer membranes for condensable components over less-condensable or non-condensable components in a gas mixture. By exposing the membrane to suitable sorbent vapor, such as propane or butane, the microvoids that constitute the free volume can be reopened. This process can restore the selectivity of an aged membrane to 70-100% of its original value, ensuring longevity and efficiency.
