Pressure Swing Adsorption refers to the process of purification of Hydrogen gas which is manufactured in a plant like rfinery. Hydrogen which is formed as a by-product in process like Reforming is also used as a raw material within the refinery process like Hydrotreating and Isomerization. So it has to be made impurities free for use. So Hydrogen is purified by the process known as pressure swing adsorption in which impurities are adsorbed on the surface and Hydrogen becomes clean.

What is centrifuge swing-out rotor?
A Centrifuge Swing-out Rotor is a part of a centrifuge which attaches to the motor and holds the sample tubes. A swing-out, as opposed to a Fixed Angle rotor, has holders that move from vertical to horizontal as the centrifuge speeds up.
What is meant by zero tail swing excavators?
Zero swing excavators are excavators that the rear/counterweight part of the machine do not extend further than the tracks. So the operator doesn't have to worry about allowing a swing radius for the rear.
What are the types of pressure?
They're 5 Kinds of Peer Pressure These are it ~ Negative Peer Pressure , Positive Peer Pressure , Heavy Peer Pressure , Indirect Peer Pressure , and Friendly Peer Pressure
Difference between set pressure and blow-off pressure?
The set pressure is the pressure at which a relief valve starts to open. When the valve is open and relieving, the pressure will be higher or lower than the set pressure, depending on the system and the valve design. That is the blow-off pressure.
What is ferrostatic pressure?
The pressure exerted by the pressure head of liquid steel in a container at bottom surface of the container is known as ferro static pressure.

How do you separate hydrogen from mixture of hydrogen and carbon monoxide?
Hydrogen can be separated from a mixture of hydrogen and carbon monoxide using techniques such as pressure swing adsorption or membrane separation. In pressure swing adsorption, the components are separated based on their ability to be adsorbed onto a solid surface under different pressures. Membrane separation exploits the difference in size and permeability of the molecules to pass through a membrane.

Why physical adsorption is reversible process?
adsorption is processs of accumulation of liquid/gases on solid surface. reversible adsorption is seen in physical adsorption where increase in pressure increases the adsorption and decrease in pressure decrease adsorption of molecules to surface that is desorption takes place
How is oxygen concentrated and put in a tank?
Oxygen is concentrated through a process called pressure swing adsorption or cryogenic distillation. The concentrated oxygen is then filled into tanks under pressure to keep it in its gaseous form. The tanks have a valve and regulator to control the flow of oxygen to the user.
What is Freundlich adsorption isotherm and Langmuir isotherm?
At a given temperature, the extent of adsorption will increase with the increase of pressure of the gas. The extent of adsorption is measured as x/m, where mi= is the mass of adsorbent and x that of adsorbate. At low pressure, x/m varies linearly with p. As per Freundlich adsorption equation Taking log both sides of the equation, we get, At low pressure, x/m=kP At high pressure, x/m=kPo This is called Freundlich adsorption isotherm at a constant temperature. Freundlich isotherm fails at high pressure and is only for physical adsorption. Langmuir isotherm is represented as x/m=ap/(1+bp) (a and b are constants) At very high pressure,(bp>>1) x/m=a/b At very low pressure,(bp<<1) x/m=ap
How is oxygen produced commercially?
Various methods have been used for the large scale production of oxygen, but at present the two mostly used are the electrolysis of an aqueous solution of dilute sulphuric acid, and the fractional distillation of Liquid Air.
Where are the gases that make up the solution we breathe separated?
An air separation plant separates atmospheric air into its primary components, typically nitrogen and oxygen, and sometimes also argon and other rare inert gases.The most common method for air separation is cryogenic distillation. Cryogenic air separation units (ASUs) are built to provide nitrogen or oxygen and often co-produce argon.Other methods such as Membrane, pressure swing adsorption (PSA) and Vacuum Pressure Swing Adsorption (VPSA), are commercially used to separate a single component from ordinary air.
Why freundlich adsorption isotherm is not applicable at high pressure?
Freundlich adsorption isotherm assumes a homogeneous surface with a finite number of adsorption sites, making it unsuitable for high pressures where interactions between adsorbate molecules become significant. At high pressures, multilayer adsorption occurs, violating the assumptions of the Freundlich isotherm which fails to account for these complex interactions. As a result, Freundlich isotherm is not applicable in conditions where multilayer adsorption dominates.
