Title: METHODS OF PREPARING AN IMPURITY-DEPLETED HYDROGEN STREAM, METHODS OF ANALYZING CONTENT OF AN IMPURITY-DEPLETED HYDROGEN STREAM, AND PRESSURE SWING ADSORPTION APPARATUSES
Abstract:
Methods of preparing an impurity-depleted hydrogen stream, methods of analyzing content of an impurity-depleted hydrogen stream from a pressure swing adsorption process, and pressure swing adsorption apparatuses are provided herein. In an embodiment, a method of analyzing content of an impurity-depleted hydrogen stream from a pressure swing adsorption process includes providing a hydrogen-containing feed stream to a pressure swing adsorption zone. The hydrogen-containing feed stream further includes an impurity content including methane and carbon monoxide. Methane and carbon monoxide are adsorbed from the hydrogen-containing feed stream in the pressure swing adsorption zone. The impurity-depleted hydrogen stream is withdrawn from the pressure swing adsorption zone, with the impurity-depleted hydrogen stream having a residual methane content and a residual carbon monoxide content. The residual methane content of the impurity-depleted hydrogen stream is sensed.
