What device is used to measure the percentage of CO2 and air in a column?
Flowmeter of CO2 and air.
Oxybaby.
pHmetry
Manometer.
The main features of a column of plates are:
Be used when working with moderate pressure.
They have a continuous contact with the gas.
Used when there are suspended solids.
They have a high degree of mechanical strength.
What is a manometer?
Provides a certain pressure inside the tank to remove CO2 from the water.
Transforms the mechanical energy supplied by the engine.
Serves to empty the reservoir and to take samples for analysis.
Used to measure the relative pressure that exists inside the column.
Mark the correct answer:
The columns filling provide a contact surface wider.
In a column plates, mass transfer is continuously.
The columns of plates are also called packed columns.
The columns filling works a very high pressures.
What we need to make the conversion of volumetric flow to mass flow of a gas mixture?
The density of the mixture and the molar masses of components.
The density of the mixture.
The molar mass
The volume of components.
The mumble bell plate ...
They have more ease of construction and are therefore cheaper.
Usually used to control the residence time optimal.
Are plates with holes that may be of different sizes.
The bells are placed under some pipes rising.
What is a rotameter?
It is a device used to regulate the flow of the stream.
Provide air inside the column.
Mark the pressure on what is inside the absorption column.
Used to measure the flow pipe.
To perform the analytical calculation of theoretical plates ...
To find the number of theoretical plates is made from the equation Kremser-Souders-Brown can only be used in the case of mixtures of gases and liquids that do not comply with the law of Henry.
The calculations start at the top of the column to reach the bottom.
The calculations start from the bottom of the column to reach the top.
Uses the principle of ideal plate, where liquid and gas streams are in equilibrium with respect to temperature and density.
What about absorption?
Unit operation of mass transfer where it contacts a gas mixture with a liquid solvent.
Physicochemical operation that involves the formation of a layer of gas, liquid or solid on the surface.
The absorption can be physical chemical, that depends on how the gas is dissolved in the liquid or how as giving react new chemicals.
It is a common phenomenon in the process of corrosion.
Mark the correct answer:
Before start the plant must ensure that the emergency switch is actuated.
The muffler serves to reduce noise that is outside the air out of the column.
The filling of a column must be chemically active for a good contact to occur between the currents.
The carbonic acid reacts reversibly with water to form bicarbonate ions and ion hydronym.
How is found the speed of flooding in a column?
From the Henry equation.
Making a comparison with the relationship HEPT.
From the graph Lobo.
Making the average speeds.
To determine the efficacy of plates and theoretical plates must be taken into account:
Conditions of temperature and velocity of the fluid.
Design and number of plates.
Flow model, temperature and design of plates.
Design, properties and fluid flow model.
Why is it important open the protect needle Oxybaby before measurement?
Because oxidized with air.
Because is polluted easily.
Because we can stick the needle.
Because it is very fragile.
What we know carbon dioxide?
Solid form can cause injuries skin and tissue.
It is a suffocating gas at concentrations of 30% or more.
It is a subproduct of combustion and respiration.
All forms of carbon dioxide are very immiscible on water.
Why use the equation of HEPT?
To calculate the equivalent height of a column of plates.
To make a comparison between a column of plates and a filling.
To calculate the equivalent height of a column filling.
To calculate the equivalent flow in a column of theoretical plates.
