Differences in the applications of pressure swing adsorption and membrane separation

There are many in the forum; the original poster can take their time to look through them

Pressure swing adsorption: When gas molecules move to a solid surface, due to the residual attractive force of the atoms on that surface, some of the molecules in the gas remain temporarily on the solid surface. The concentration of these molecules on the solid surface increases, and this phenomenon is known as the adsorption of gas molecules on a solid surface. The solid that adsorbs substances is called an adsorbent, while the substance that is adsorbed is called the adsorbate. Based on the nature of the gravitational field between the adsorbate and the adsorbent, adsorption can be divided into chemical adsorption and physical adsorption. Membrane separation: The membrane separation process is an efficient and environmentally friendly separation method. It represents a high-tech approach that combines elements from multiple disciplines, and it exhibits a variety of properties in terms of physical, chemical, and biological characteristics, offering numerous advantages. Compared with traditional separation techniques such as distillation, adsorption, absorption, extraction, and cryogenic separation, membrane separation technology has the following characteristics. 1. Efficient separation process 2. Low energy consumption 3. Operating temperature close to room temperature 4. Good quality stability 5. Continuous operation 6. High flexibility 7. Purely physical process 8. Environmentally friendly
