2021年2月19日 · There are two types of gas absorption: chemical and physical absorption. Chemical gas absorption- reaction between the absorbent and solute. Examples include using NaOH as an absorbent to dissolve acid gas, dissolving CO2 and H2S in aqueous solution of MEA. Physical absorption- No significant chemical reactions between the absorbent and solute.

In absorption (also known as gas scrubbing, gas absorption, or gas washing), one or more species transfer from the gas phase to a liquid solvent. Solutes or absorbates are the species that are transferred to the liquid phase.

2022年10月24日 · Chemical gas absorption focuses on the reaction between the solvent and the gas (solute) where the solute is selectively dissolved. The solute-rich solution is sent to a stripping column to recover the solvent, while the desorbed gas is compressed to a …

In gas absorption, soluble vapors are more or less absorbed in the solvent from its mixture with inert gas. The purpose of such gas scrubbing operations may be any of the following; a) For Separation of component having the economic value. b) …

2022年3月19日 · Gas-liquid absorption columns are primarily used to clean gas streams from chemicals that should not be released into the environment. Sulfur dioxide (SO 2), carbon dioxide (CO 2) and other gases are found in industrial waste streams and contribute to …

Acetone is being absorbed by water in a packed tower having a cross-sectional area of 0.186 m2 at 293 K and 101.32 kPa (1 atm). The inlet air contains 1 = 2.6 % acetone and outlet 2 = 0.5 %.

Put an adiabatic flash first. if the feed is not two phase at the desired pressure, use an isothermal flash. Change the temperature until you get some separation in the direction you want. To do this list the components in increasing boiling point and determine key components. Light key goes mostly to the top. Heavy key goes mostly to bottom.
