What are the applications of gas absorption-adsorption in industry?
Gas absorption-adsorption is used in industries such as petrochemical, pharmaceutical, and environmental for removing contaminants from gas streams, purifying gases, and capturing valuable components. It is also used in gas storage, gas separation, and catalysis processes. Additionally, it plays a critical role in air purification systems and in the production of high-purity gases for various industrial applications.
What is the favorable condition for liquefaction of gases?
The temperature must be below the critical point and the phase can change to liquid by cooling the gas. If the gas is at conditions of temp and pressure below the triple point, the gas will instead be converted to a solid.
Why adsorption occur?
Adsorption occurs due to the attractive forces between molecules of a solid surface and molecules or ions in a fluid or gas. These attractive forces lead to the accumulation of the molecules or ions on the surface of the solid, creating a thin layer. Adsorption can be influenced by factors such as the surface area and nature of the adsorbent and the concentration and properties of the adsorbate.
What would happen if the volume of gas decreased and then increased?
The temp of the gas would first rise, then drop. If the final volume of the gas is lower than the volume at the start, the temp will be higher than at the start. If the final volume is greater than at the start, then the temp of the gas will be lower than at the start.
Why can gasses be easily liquefied?
easily liquifiable gases like Cl2, NH3,SO2,HCl are readily adsorbed because the critical temp of these gases are more. so it is easily liquified and adsorbed more readily.[critical temp is the minimum temp above which a gas cannot be liquified]easily liq. gases possess greater vanderwaals forces ,so they are adsorbed readily.these are the 2 reasons why these gases are readily adsorbed than permanent gases like H2, O2.N2 . etc
Highest temp of a gas?
Critical temperature
What refers to the temperature above which a gas cannot be liquefied by an increase in pressure?
This is known as the "Critical Temperature". For example, CO2 has a critical temp of 31.2 degrees C and NH3 has a critical temp of 132 degrees C

What is the critical temperature of dimethyl sulphoxide?
447_c is the critical temp of dimethyl sulphoxide
Is ammonia a gas temp?
gas at room temp
What is adsorption site?
An adsorption site is a location on a surface where molecules or particles can adhere or bind due to attractive forces. It is where adsorption occurs, where a substance accumulates on the surface of another material. Adsorption sites are important in processes like catalysis, gas separation, and water treatment.
How does adsorption work in reality?
In reality, adsorption is a process where molecules in a gas or liquid adhere to the surface of a solid. This occurs due to the attractive forces between the molecules and the solid surface. Adsorption is used in various applications such as purifying gases, wastewater treatment, and catalysts.
What is a gas at room temp?
a gas.
What is the different between desorption and adsorption?
desorption-changing from an adsorbed state on a surface to a gaseous or liquid state and adsorption-the accumulation of molecules of a gas to form a thin film on the surface of a solid
What is the favorable condition for liquefaction of gases?
The temperature must be below the critical point and the phase can change to liquid by cooling the gas. If the gas is at conditions of temp and pressure below the triple point, the gas will instead be converted to a solid.
What is difference between critical temperature and boiling point?
The critical temperature is the highest temperature at which a substance can exist in a distinct liquid and gas phase, above which the substance becomes a supercritical fluid. The boiling point is the temperature at which the vapor pressure of a liquid is equal to the external pressure, causing the liquid to transition into a gas phase.
