Carbon Dioxide Removal from Flue Gases by Absorption/Desorption in Aqueous Diethanolamine Solutions

In this work a review of the currently available methods for carbon dioxide removal from flue gasses is given. Some of them are commercially available, while others are still under development. Special attention is given to detailed description of the methods based on hemi sorption by aqueous solutions of alkanol amines, which found wide commercial use in industry. Selection of appropriate absorbent, process equipment, methods, working parameters, combustion process etc. are some of key points that will be reviewed within this work in order to present advantages and limitations of carbon dioxide removal methods. In the experimental section density, viscosity and refractive index of insufficiently investigated carbon dioxide removal agents, such as monoisopropanolamine (MIPA), diisopropanolamine (DIPA), triisopropanolamine (TIPA) and currently widely used dietanolamine (DEA) are provided. The data obtained are crucial for the equipment design and process optimization.

Phase Dispersion

Whenever possible, neutralization of alkaline wastewater should involve low-cost acid. It is conventional to make use of carbonic acid produced via the reaction of carbon dioxide (contained in flue gases) with water according to the following equation: Carbon dioxide content in the flue gas stream varies from 10% to 15%. The flue gas stream may either be passed to the wastewater contained in the recarbonizers, or. enter the scrubbers (which are continually sprayed with wastewater) from the bottom in oountercurrent. The reactors, in which recarbonation occurs, have the ability to expand the contact surface between gaseous and liquid phase. This can be achieved by gas phase dispersion in the liquid phase (bubbling), by liquid phase dispersion in the gas phase (spraying), or by bubbling and spraying, and mixing. These concurrent operations are carried out during motion of the disk aerator (which is a patent claim). The authors describe the functioning of the disk aerator, the composition of the wastewater produced during wet gasification of carbide, the chemistry of recarbonation and decarbonation, and the concept of applying the disk aerator so as to make the wastewater fit for reuse (after suitable neutralization) as feeding water in acetylene generators.
