HEPA filters can be identified as choked by observing reduced airflow, increased noise, or visible dust accumulation.
Reduced airflow through the filter
Increased noise from the system
Visible dust accumulation on the filter surface
Nitrogen plants separate nitrogen from air to produce high-purity nitrogen gas for various industrial applications.
Nitrogen plants use a process called cryogenic distillation to separate nitrogen from air.
Air is compressed and cooled to very low temperatures to liquefy it.
The liquid air is then distilled to separate nitrogen from other gases like oxygen and argon.
The nitrogen gas is collected and purified to achieve th...

pH is a measure of acidity or alkalinity in a solution, ranging from 0 to 14.
pH stands for 'potential of hydrogen'
It measures the concentration of hydrogen ions in a solution
A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline
The pH scale is logarithmic, meaning each unit represents a tenfold difference in acidity or alkalinity
Examples: lemon juice has a pH of around 2, water has a pH of 7, and b
Titrations is a laboratory technique used to determine the concentration of a substance in a solution.
It involves adding a known amount of a solution of known concentration to a solution of unknown concentration until a reaction is complete.
The point at which the reaction is complete is called the endpoint.
The amount of the known solution added is used to calculate the concentration of the unknown solution.
Titrations c...
Acid and base are chemical substances that have opposite properties and can react with each other.
Acid: hydrochloric acid (HCl), sulfuric acid (H2SO4), acetic acid (CH3COOH)
Base: sodium hydroxide (NaOH), potassium hydroxide (KOH), calcium hydroxide (Ca(OH)2)

Distillation columns are classified based on their internal structure and operation.
Distillation columns can be classified as batch or continuous columns.
Common types of distillation columns include simple distillation columns, fractional distillation columns, and steam distillation columns.
The type of distillation column used depends on the specific separation requirements and properties of the components being separa
