Title: Jack W. Roach: Innovator in Organic Solvent Recovery
Introduction
Jack W. Roach is a notable inventor based in Oklahoma City, OK (US). He has made significant contributions to the field of organic solvent recovery, holding a total of 3 patents. His work focuses on innovative methods for separating solvents from various materials, which has implications for industries such as refining and chemical processing.
Latest Patents
One of Roach's latest patents is titled "Recovery of Organic Solvents from Liquid Mixtures." This method involves recovering light organic solvents from a liquid mixture that contains both the solvent and a product material, such as asphaltenes or coal liquefaction products. The process treats the solvent-product material mixture to separate a first vapor phase rich in solvent and a first liquid phase rich in product material. The first liquid phase is then contacted with steam under shearing conditions, leading to the separation of a second vapor phase rich in steam and solvent, and a second liquid phase that is rich in product material and substantially depleted of solvent. The solvent is ultimately recovered from both vapor phases.
Another significant patent is the "Process for Separating Bituminous Materials." This process allows for the separation of a solvent from bituminous material through pressure reduction and steam stripping, without carry-over of entrained bituminous material. The fluid-like phase of bituminous material and solvent is reduced in pressure and introduced into a steam stripper. The solvent vaporizes upon pressure reduction, forming a mist of fine bituminous material particles that become dispersed in the vaporized solvent. The vaporized solvent and associated mist are then separated from the bituminous material in the stripper, leading to the recovery of the solvent.
