Pressure swing adsorption vessels fatigue analysis

The hydrogen (H2) plant in a refinery produces high-purity (99.9+ vol%) H2 products using a licensed pressure swing adsorption (PSA) purification process to fulfill the H2 makeup needs of refinery hydroprocessing facilities.

The hydrogen (H2) plant in a refinery produces high-purity (99.9+ vol%) H2 products using a licensed pressure swing adsorption (PSA) purification process to fulfill the H2 makeup needs of refinery hydroprocessing facilities, as shown in FIG. 1. The H2 recovery/purification process consists of two trains. The PSA process purifies H2 by filtering heavier gases/impurities from the process stream as it passes through an adsorber vessel. Each train has 12 identical adsorbers in four groups of three vessels. Each vessel goes through four stages in a cycle: adsorption, depressurization, desorption (regeneration) and repressurization. Adsorption at high pressure pulls all the heavier gases/impuritie
