Advances in Carbon Capture reviews major implementations of CO2 capture, including absorption, adsorption, permeation and biological techniques. For each approach, key benefits and drawbacks of separation methods and technologies, perspectives on CO2 reuse and conversion, and pathways for future CO2 capture research are explored in depth. The work presents a comprehensive comparison of capture technologies. In addition, the alternatives for CO2 separation from various feeds are investigated based on process economics, flexibility, industrial aspects, purification level and environmental viewpoints.

• Explores key CO2 separation and compare technologies in terms of provable advantages and limitations
• Analyzes all critical CO2 capture methods in tandem with related technologies
• Introduces a panorama of various applications of CO2 capture

Abstract

This chapter summarizes previous studies on CO₂ absorption with a special focus on amine scrubbing technology. First, an overview of carbon capture technologies is presented, including postcombustion, precombustion, and oxy-combustion capture. This subject is expounded by introducing different types of common solvents used in carbon absorption processes along with their specifications and disadvantages. In the next stage, various experimental methods and techniques of vapor-liquid equilibrium measurement, as well as different thermodynamic models for amine-H₂O-CO₂ systems presented in the literature, are discussed. Furthermore, the various mechanisms for CO₂ absorption reaction kinetics based on the zwitterion, termolecular, and base-catalyzed hydration are described. Finally, mass transfer phenomena for CO₂ absorption by amine solutions, amine regeneration, and amine degradation are investigated.

3.1: Introduction

Gas-liquid absorption is a unit process to separate a specific gas from the gas mixture by using an appropriate solvent. Absorption is usually used to reduce impurities to enhance process efficiency, eliminating toxic gaseous from a gas mixture, etc. [1]. Such useful applications for this process are recovery alcohol vapor, acid gas removal, and separation of hydrocarbons by water, alkaline aqueous solution, and hydrocarbon oil, respectively [2]. Besides various usages of gas-liquid absorption, CO₂ capture in industry, nature, and also the energy sector by common solvents known as an effective method for this CO₂ removal from gas streams [3, 4].
