Evaluation of Hydrodynamics and Absorption Efficiency to Capture CO2

Greenhouse gas emissions have increased exponentially since the start of the industrial revolution. The main dominant gas is carbon dioxide which is mainly released from fuel combustion processes. Developing a process to capture the carbon dioxide emissions is crucial to avoid dramatic climate change. The absorption column is a widely used separation unit for gas emissions treatment. This book explores a wide range of carbon dioxide absorbents and the internal design options of the column to minimise the capture cost. The internal design affects the hydrodynamics of the column which has been evaluated to maintain the operation at the optimum level. The pressure drop and flooding velocities were the main hydrodynamics properties to be analysed. Series of experiments were conducted in a pilot plant absorption column mainly to investigate the hydrodynamics of the column and its capture efficiency. The column has double packing beds of a total height of 2.8 m and a diameter of 0.3 m. The beds are equally divided into glass structured packing and plastic pall ring random packing.
