gas absorption的意思|示意

The term \"gas absorption\" refers to the process of gas molecules being dissolved into a liquid. This can be done through either chemical or physical means, depending on the need of the application.

In chemical absorption, the gas molecules interact with a chemical species present in the liquid, leading to the formation of a chemical compound, and the dissolved gas. Examples of this include the absorption of carbon dioxide in water, forming carbonic acid and bicarbonate ions. An example relevant to air conditioning is the absorption of ammonia gas in water, producing ammonium ions.

In physical absorption, the gas molecules simply dissolve into the liquid medium. This typically happens when the gas molecules are smaller than the liquid molecules, such as in the case of oxygen gas being dissolved in water. The technical term for this phenomenon is Henry's Law, which states that the solubility of a gas in a given liquid is determined by the pressure of the gas over the liquid, and its solubility coefficient.

Gas absorption is an important process in various applications, such as in air conditioning, water purification and wastewater treatment systems. In these systems, gases such as carbon dioxide, ammonia, chlorine and ozone are used to treat the water, and absorbed into the liquid in order to achieve the desired effect.
