What is flooding velocity in absorption column?
Flooding velocity in an absorption column refers to the gas or liquid flow rate at which the column becomes saturated with liquid, leading to excessive liquid accumulation and reduced mass transfer efficiency. Beyond this velocity, the liquid can no longer effectively contact the gas, causing a decline in performance and potentially leading to operational issues. Understanding and calculating the flooding velocity is essential for designing and operating absorption columns to ensure optimal separation and absorption processes.
Heat exchanger for ammonia absorption refrigeration system?
there are two type of heat exchanger in absorption refrigeration, first is liquid heat exchanger and other is gas heat exchanger.both heat exchanger function is same, to transfer heat (hot medium to cold medium) without violate second newton law of thermodynamics. liquids heat exchanger is between boiler and absorber vessel mean while gas heat exchanger between evaporator and absorber.
How do you describe Wet corrosion by evolution of hydrogen and absorption of oxygen?
Wet corrosion involving the evolution of hydrogen and absorption of oxygen typically occurs in aqueous environments where metals are exposed to moisture. In this process, the metal oxidizes, leading to the release of electrons and hydrogen ions, which can result in the evolution of hydrogen gas. Concurrently, oxygen from the environment is absorbed, facilitating further electrochemical reactions that accelerate the corrosion process. This interplay between hydrogen evolution and oxygen absorption is crucial in understanding and mitigating corrosion in various applications.
How do you calculate the efficiency of vapour absorption machine?
how to calculate the vapour absorption mechine efficiency and per TR steam consumption
What is absorption refrigeration?
absorption refrigeration is when ice is put in a compartment above a warmer compartment and absorbs rising warm air thus making it colder.
What is the Importance of gas absorption is pharmacy?
It is a mass transfer process involving the absorption of gas by a liquid.devices available for gas absorption are packed towers.
What are the different types of absorption column?
Major types of Absorption columns are liquid-liquid absorption columns, Gas-liquid absorption columns.
Is it true that a low density gas must be hot in order to produce an absorption line?
No, a low-density gas does not need to be hot in order to produce an absorption line. Absorption lines are formed when atoms in a gas absorb specific wavelengths of light. The presence of these lines does not depend on the temperature of the gas, but rather on the composition and energy levels of the atoms within the gas.
What is hydration and fluid absorption?
As the name suggests,hydra refers to water and hence hydration means absorption of water and fluid absorption means absorption of any liquid or gas. lol
What is a gas turning to a liquid?
Ammonia (it tranforms into ammonium hydroxide by Gas-absorption refrigerator).
What is the effect of pressure on absorption?
Increasing pressure can enhance the absorption process by forcing more gas molecules into the absorbing material. This is due to the increased concentration of gas molecules that can be dissolved or trapped in the absorbent. However, the effect of pressure on absorption efficiency can vary depending on the specific gas-liquid system and the absorbent material used.
How does absorption refrigeration work and what are its key principles?
Absorption refrigeration works by using a refrigerant that is absorbed into a liquid solution, which is then heated to release the refrigerant as a gas. The key principles of absorption refrigeration include the use of heat to drive the refrigeration cycle, the absorption of the refrigerant into a liquid solution, and the release of the refrigerant as a gas through heating.
What is the process of absorption?
Adsorption is the process by which a gas dissolves into the surface of a solid, which will normally be metal. There are actually two types of absorption. Adsorption and Absorption ABsorption actually happens in the digestive process.
Can you know how the ionic absorption takes place?
yes, you can because during ionic absorption it causes gas in your abdonminal area. The absorption of minerals normally takes place in the small intestines.
What is the process of absorbing gas through the skin?
The process of absorbing gas through the skin is called dermal absorption. It occurs when gas molecules pass through the skin barrier and into the bloodstream. Factors such as concentration of the gas, duration of exposure, skin health, and temperature can affect the rate of absorption.
What is the difference between absorption and stripping?
An absorption is a separation process where a gas is absorbed to a liquid. For example, an aqueous gas that has a tendency to leave solution can be forced to stay in solution through the addition of an absorbent. Stripping is the reverse separation reaction. A stripping process is the removal of solute from a liquid phase to a gas phase.
Are The absorption lines for a cool thin gas identical in color and energy to the emission lines of the same gas if hot enough to glow?
No, the absorption lines of a cool thin gas are not identical in color and energy to the emission lines of the same gas when hot enough to glow. Absorption lines are produced when certain wavelengths of light are absorbed by the gas, while emission lines are produced when the gas emits light at specific wavelengths. The emission lines will be at different wavelengths compared to the absorbed wavelengths.
