Title: Lora G Toy: Innovator in Membrane Technology
Introduction
Lora G Toy is a prominent inventor based in San Francisco, CA, known for her significant contributions to membrane technology. With a total of six patents to her name, she has made remarkable advancements in the field of separating hydrocarbons and restoring membrane properties.
Latest Patents
One of her latest patents is the "Olefin separation membrane and process." This invention involves a membrane and process designed for separating unsaturated hydrocarbons from fluid mixtures. Unlike previously known membranes, this innovation allows both the feed and permeate streams to be dry. The membrane is characterized by its selectivity for unsaturated hydrocarbons over saturated hydrocarbons, achieving a pressure-normalized flux of at least about 5.times.10.sup.-6 cm.sup.3 (STP)/cm.sup.2 .multidot.s.multidot.cmHg. This selectivity and flux are measured in a substantially dry environment.
Another notable 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.
Career Highlights
Lora G Toy is currently employed at Membrane Technology and Research, Inc., where she continues to innovate and develop new technologies. Her work has significantly impacted the field of membrane technology, particularly in the separation and restoration processes.
