Title: Innovations and Contributions of John J. Bowser

Introduction

John J. Bowser, based in Newark, DE, has made significant strides in the field of membrane technology through his innovative inventions. With a total of nine patents to his name, Bowser has effectively contributed to the advancement of methods for separating components of liquid mixtures and controlling emissions in storage operations.

Latest Patents

Among his latest patents is a groundbreaking method for organic fluid permeation through fluoropolymer membranes. This invention allows for the separation of components in liquid mixtures by using a nonporous membrane. The selectively permeable layer works effectively when a pressure gradient is applied, achieving unusually high transmembrane flux under specific pre-treatment conditions. These conditions include maintaining some residual membrane casting solvent and saturating the membrane with a component of the mixture prior to separation.

Additionally, Bowser has developed a cyclic membrane separation process aimed at controlling volatile organic compounds (VOC) emissions. This cyclic process operates by maintaining a vacuum in the storage tank ullage and includes two phases. In the first phase, ullage vapor is discharged through a vapor recovery system where VOCs are stripped from vented gas using a selectively gas permeable membrane. The second phase involves allowing gas pressure to rise in the ullage while the membrane is inoperative, charging ambient air to the separation unit during this part of the cycle.

Career Highlights

Throughout his career, Bowser has been associated with prominent companies such as W. L. Gore & Associates, Inc. and Cps Technology Holdings LLC.
