Oxygen Production and PSA Process

The video explains the importance of oxygen cylinders during the coronavirus pandemic and details the process of oxygen production using Pressure Swing Adsorption (PSA). It covers the composition of air, the role of zeolites in separating nitrogen from oxygen, and the continuous production of oxygen. The video also discusses methods for storing and supplying oxygen, emphasizing the efficiency of the PSA process in generating high-purity oxygen.

Why has the manufacturing of oxygen cylinders increased recently?

• For agricultural purposes

• To support space exploration

• Because of the coronavirus pandemic

• Due to a rise in industrial demand

What percentage of the air we breathe is composed of oxygen?

• 78%

• 21%

• 0.9%

• 0.1%

What is the primary method used to generate oxygen in manufacturing plants?

• Membrane separation

• Electrolysis

• Pressure Swing Adsorption (PSA)

• Cryogenic distillation

What is the first step in the PSA process for oxygen production?

• Purifying the air

• Capturing air from the atmosphere

• Filtering dust and polyp

• Compressing the air

What is the role of the purification unit in the PSA process?

• To separate nitrogen from oxygen

• To store the oxygen

• To compress the air

• To remove water, carbon dioxide, and hydrocarbons

How do zeolites function in the PSA process?

• They compress the air

• They absorb oxygen

• They absorb nitrogen

• They store the oxygen

What happens when the zeolite becomes saturated with nitrogen?

• The pressure is increased

• It is replaced with new zeolite

• The oxygen is released

• The pressure is reduced to atmospheric levels

What is the output concentration of oxygen produced by the PSA process?

• 100%

• 75%

• 95%

• 85%

In what forms can oxygen be stored after production?

• In liquid form only

• In solid form

• In gaseous form only

• In cylinders, vacuum insulated evaporators, or manifold cylinder banks

How is oxygen typically supplied to required areas after production?

• Through railways

• By air transport

• Via pipeline or cylinders

• Through trucks
