This document discusses various mass transfer separation processes used in chemical industries. It describes core separation processes like distillation, gas absorption, liquid-liquid extraction, drying, adsorption, crystallization and membrane separation. These processes are classified based on the phases involved (gas, liquid, solid) and the mechanism of separation - contact of immiscible phases, indirect contact of miscible phases through a membrane, direct contact of miscible phases, or use of surface phenomena. Examples of typical applications and separation processes are provided for different combinations of phases.

The processing technique employing a suspension or fluidization of small solid particles in a vertically rising stream of fluid usually gas so that fluid and solid come into intimate contact. This is a tool with many applications in the petroleum and chemical process industries. Suspensions of solid particles by vertically rising liquid streams are of lesser interest in modern processing, but have been shown to be of use, particularly in liquid contacting of ion-exchange resins. However, they come in this same classification and their use involves techniques of liquid settling, both free and hindered (sedimentation), classification, and density flotation.
This presentation related to molecular diffusion of molecules in gases and liquids. Also includes inter-phase mass transfer and various theories related to it like two film theory, penetration theory and surface renewal theory.

Molecular sieve is a moisture adsorbent having same-sized pores, which are less than 10 angstrom in diameter. This gives the moisture absorbent considerable surface area and thus increases its adsorption capacity. If we take a look at their composition, molecular sieves are also called zeolites.

How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

Classification of
mass transfer
processes
2. Mass transfer separation processes
• In mass transfer separation processes, the mixture of substances is
transformed into two or more products differing in composition.
• Core separation processes in chemical industry are:
• distillation
• gas absorption and stripping
• liquid-liquid and liquid-solid extraction
• drying of a wet solid
• adsorption
• crystallization
• membrane separation
• separation of multicomponent mixtures
• There are also several other processes that are not discussed in this course.
3. Typical applications
Separation process Typical applications
Distillation Fractionation of crude oil
Gas absorption Removal of CO2 from synthesis gas
Stripping (desorption) Stripping volatile substances from wastewater by steam
Adsorption Drying of air
Drying Drying of fruits
Crystallization Production of salt and sugar
Liquid-liquid extraction Removal of benzene from gasoline
Membrane extraction Concentration of milk
Solid-liquid extraction Extraction of caffein from coffee
4. Principle mechanisms
• There are three phases encountered in
practice: gas, liquid and solid. If mass transfer
occurs between two phases, there are total
nine possible combinations of operations.
If the direction is not concidered, there are
six combinations (bolded in the table).
• The mass transfer operations can also be
classified in four mechanisms:
1. Contact of two immiscible phases
2. Indirect contact of miscible phases
3. Direct contact of miscible phases
4. Use of surface phenomena
• Let’s take a closer look at these.
Phase undergoing
treatment
Phase performing
treatment
1 Gas Gas
2 Gas Liquid
3 Gas Solid
4 Liquid Gas
5 Liquid Liquid
6 Liquid Solid
7 Solid Gas
8 Solid Liquid
9 Solid Solid
5. Contact of two immiscible phases
• When to immiscible phases are in contact, mass transfer or diffusion may
occur through the interphase between the phases. Most of the real-world
industrial mass transfer processes include in this category.
Category Examples of separation processes
Gas-gas Cannot be realized, because all gases are soluble in each other.
Gas-liquid Distillation, gas absorption, desorption/stripping, humidification
Gas-solid Fractional sublimation, drying, desorption, adsorption
Liquid-liquid Liquid-liquid extraction, fractional extraction
Liquid-solid Fractional solidification, crystallization, leaching
Solid-solid No industrial separation operations (so slow rate of diffusion)
6. Indirect contact of miscible phases
• In this category, the phases are separated with diffusion through a
permeable or semi-permeable membrane. The membrane is necessary to
prevent the mixing of the phases. It also selectively separates materials.
• Membranes can be organic or inorganic.
• There are three possible combinations within phases shown in the table
below. There is no phase change associated with the separation.
Category Examples of separation processes
Gas-gas Gaseous diffusion, gas permeation, effusion
Gas-liquid Permeation separation
Liquid-liquid Dialysis, electrodialysis, osmosis, reverse osmosis
Solid-solid No practical applications in the chemical process industry
7. Others
• When miscible phases has a direct contact, it is difficult to maintain the
concentration gradient.
• These operations have only a few industrial applications: Thermal diffusion,
sweep diffusion, atmolysis and centrifugation of a gas mixture.
• Foam separation is an example of use of surface phenomena. It should
not be confused with the flotation process, where insoluble soplid particles
are removed from slurries.
• In foam separation, a foam is formed by bubbling air through the solution.
The foam is collected and the solute can be concentrated.
• This classification into four groups categorizes all the major mass transfer
operations. Although, new operations continue to be developed.
