Chapter 1
Simulation of Adsorption Processes

This chapter introduces four key concepts inherent to all adsorptive separations, before presenting how these concepts are applied in rigorous simulations. Sections 1.1 and 1.2 provide a high-level overview of adsorption covering the history and driving forces involved. Section 1.3 discusses adsorption equilibrium and summarizes the theoretical assumptions behind the various mathematical models that have been used to describe it. Section 1.4 explains a number of terms and concepts inherent to working with packed beds. Section 1.5 covers the “classic” industrial adsorber configurations, along with commonly used industrial adsorbents. Section 1.6 onward discusses how to apply these concepts in Aspen Adsorption, specifically to pressure swing adsorption (PSA) for oxygen isolation from air (Section 1.7) and hydrogen separation from light hydrocarbons (Sections 1.8 and 1.9), and temperature swing adsorption (TSA) for air drying (Section 1.10). Section 1.11 provides the conclusions of the chapter. Section 1.12 presents practice problems to allow readers to apply the concepts described in this chapter. Section 1.13 includes the nomenclature, and Section 1.14 gives the bibliography.

1.1 Introduction to Gas-phase Adsorption Technologies

Gas-solid separations are incredibly important industrial problems, but have a short history compared to processes such as distillation. The difficulties associated with handling solid adsorbents require both creative process design and detailed understanding of the adsorptive properties of various solids. The investigation of solid-gas absorptivity began in the late 1700s, but it was not until the early 1900s that any industrial application was found. By the end of the 1950s, engineers had already filed patents on the major gas-adsorptive separations we know today, such as hydrogen sulfide removal [1], oxygen/nitrogen separation [2], and some drying applications [3, 4] as well as numerous short-chain hydrocarbon separations [5–7].

Over the years, refinements to these technologies have appeared, and numerous authoritative textbooks have consolidated the scientific knowledge of the subject. It is fair to say that at this point, adsorption technologies are fairly well understood, and there are a variety of resources available for the interested reader.
