Mechanism of Distillation,simple distillation steam &fractional distillation...
Distillation is a technique used to separate liquids based on their boiling points. It involves heating a liquid mixture so that the more volatile components vaporize and pass into a condenser where they condense. Simple distillation can separate two liquids with a boiling point difference of at least 70°C, while fractional distillation uses a column with multiple plates to separate very similar boiling points. Vacuum distillation uses reduced pressure to lower the boiling point of components. Steam distillation is used for heat-sensitive materials and allows distillation at lower temperatures.

CLIMBING FILM EVAPORATOR.pptx
The climbing film evaporator uses long, narrow steam-jacketed tubes to heat and evaporate liquid. As the preheated liquid rises through the tubes, bubbles form and coalesce into larger bubbles that trap liquid and rise as well. This forms a liquid film on the tube walls that rapidly vaporizes. The mixture of vapor and entrained liquid is then separated by an entrainment separator at the top, with vapor exiting and concentrated liquid collected below. Climbing film evaporators are well-suited for heat-sensitive and foaming liquids due to their short contact time and ability to break foam. However, they are also expensive to construct and maintain.

Distillation
Distillation is a process that separates mixtures into individual components based on differences in their boiling points. It works by heating the mixture to vaporize components with lower boiling points, which are then cooled and condensed.
The key principles are that vapor pressure increases with temperature, allowing the lower boiling components to vaporize first. According to Raoult's law, the vapor produced will be enriched in the more volatile components compared to the liquid mixture.
There are several types of distillation including simple, fractional, vacuum, and azeotropic distillation. Simple distillation is used when components have very different boiling points while fractional distillation with multiple stages is needed for similar boiling points. Vacuum distillation lowers the
role of Vacuum distillation in refinery
Vacuum distillation is used in oil refineries to further separate and refine the bottoms leftover from atmospheric distillation. It allows for distillation of compounds with high boiling points without thermal cracking by reducing the pressure and lowering the boiling points. Vacuum distillation units in refineries can have columns up to 14 meters wide and 50 meters tall, processing up to 25,400 cubic meters of feed per day. This additional refinement produces more valuable petroleum products from the heavier fractions of crude oil.

Extraction
This document discusses different types of solid-liquid and liquid-liquid extraction processes. Solid-liquid extraction, also called leaching, involves removing soluble components from an insolute matrix using a solvent. It occurs through diffusion of the solvent into the solid and diffusion of the dissolved components out of the solid into the solution. Common solid-liquid extraction techniques include maceration, percolation, digestion, and countercurrent extraction using equipment like diffusion batteries, rotocel extractors, and screw extractors. Liquid-liquid extraction relies on the partition of compounds between two immiscible liquid phases. Large-scale equipment used in extraction includes mixers, towers, spray towers, and agitated columns.

Distillation Column
Distillation is a process that separates liquid mixtures into individual fractions based on differences in boiling points. It works by heating the mixture to vaporize components with lower boiling points. There are two main types of distillation columns - batch columns which process feed intermittently, and continuous columns which process a steady stream of feed. Distillation columns contain internals like trays or packings to enhance separation, a reboiler for vaporization, a condenser to cool vapors, and a reflux drum to collect condensed liquids and provide reflux. Separation occurs due to differences in vapor pressure and relative volatility between components in the mixture.
Liquid membrane
Liquid membranes can be either immobilized liquid membranes (ILM), also called supported liquid membranes (SLM), or emulsion liquid membranes (ELM). ILMs are made by immersing a thin porous solid film with a liquid, allowing molecules to diffuse through the liquid in the pores. ELMs contain small liquid globules of one liquid suspended in another liquid medium. Liquid membranes allow separation through passive diffusion, facilitated transport using a carrier molecule, or coupled transport where the carrier couples the flow of two species. Common applications include removal of specific ions, gases, and organic compounds.

3) Equilibrium or flash distillation involves heating a liquid mixture to partially vaporize it in a single stage, separating the vapor and liquid which approach equilibrium compositions.
Distillation
Distillation is a process that separates mixtures into their component parts based on differences in volatility. It works by heating the mixture to vaporize the more volatile components, which are then condensed and captured separately from the less volatile components. There are several types including batch, continuous, fractional, vacuum, and zone distillation. The efficiency of distillation can be measured by assessing the purity of separated components over time. Distillation has many industrial and commercial applications such as in oil refining, producing purified gases and solvents, separating fermentation products, and more.

Steam distillation and azeotropic distillation are separation processes.
Steam distillation uses steam to distill temperature sensitive compounds like essential oils at lower temperatures to prevent decomposition. It produces a mixture of water and organic distillate that can be separated.
Azeotropic distillation uses an entrainer added to the original mixture to form a new azeotrope that distills off, allowing separation of the original components which could not be separated otherwise due to forming an azeotrope. Both processes exploit differences in volatility between mixture components to achieve separation.

Understanding User Needs and Satisfying Them
https://www.productmanagementtoday.com/frs/26903918/understanding-user-needs-and-satisfying-them
We know we want to create products which our customers find to be valuable. Whether we label it as customer-centric or product-led depends on how long we've been doing product management. There are three challenges we face when doing this. The obvious challenge is figuring out what our users need; the non-obvious challenges are in creating a shared understanding of those needs and in sensing if what we're doing is meeting those needs.
In this webinar, we won't focus on the research methods for discovering user-needs. We will focus on synthesis of the needs we discover, communication and alignment tools, and how we operationalize addressing those needs.
Industry expert Scott Sehlhorst will:
• Introduce a taxonomy for user goals with real world examples
• Present the Onion Diagram, a tool for contextualizing task-level goals
• Illustrate how customer journey maps capture activity-level and task-level goals
• Demonstrate the best approach to selection and prioritization of user-goals to address
• Highlight the crucial benchmarks, observable changes, in ensuring fulfillment of customer needs
The Evolution and Impact of OTT Platforms: A Deep Dive into the Future of Ent...
This presentation provides a thorough examination of Over-the-Top (OTT) platforms, focusing on their development and substantial influence on the entertainment industry, with a particular emphasis on the Indian market.We begin with an introduction to OTT platforms, defining them as streaming services that deliver content directly over the internet, bypassing traditional broadcast channels. These platforms offer a variety of content, including movies, TV shows, and original productions, allowing users to access content on-demand across multiple devices.The historical context covers the early days of streaming, starting with Netflix's inception in 1997 as a DVD rental service and its transition to streaming in 2007. The presentation also highlights India's television journey, from the launch of Doordarshan in 1959 to the introduction of Direct-to-Home (DTH) satellite television in 2000, which expanded viewing choices and set the stage for the rise of OTT platforms like Big Flix, Ditto TV, Sony LIV, Hotstar, and Netflix. The business models of OTT platforms are explored in detail. Subscription Video on Demand (SVOD) models, exemplified by Netflix and Amazon Prime Video, offer unlimited content access for a monthly fee. Transactional Video on Demand (TVOD) models, like iTunes and Sky Box Office, allow users to pay for individual pieces of content. Advertising-Based Video on Demand (AVOD) models, such as YouTube and Facebook Watch, provide free content supported by advertisements. Hybrid models combine elements of SVOD and AVOD, offering flexibility to cater to diverse audience preferences.
Content acquisition strategies are also discussed, highlighting the dual approach of purchasing broadcasting rights for existing films and TV shows and investing in original content production. This section underscores the importance of a robust content library in attracting and retaining subscribers.The presentation addresses the challenges faced by OTT platforms, including the unpredictability of content acquisition and audience preferences. It emphasizes the difficulty of balancing content investment with returns in a competitive market, the high costs associated with marketing, and the need for continuous innovation and adaptation to stay relevant.
The impact of OTT platforms on the Bollywood film industry is significant. The competition for viewers has led to a decrease in cinema ticket sales, affecting the revenue of Bollywood films that traditionally rely on theatrical releases. Additionally, OTT platforms now pay less for film rights due to the uncertain success of films in cinemas.
Looking ahead, the future of OTT in India appears promising. The market is expected to grow by 20% annually, reaching a value of ₹1200 billion by the end of the decade. The increasing availability of affordable smartphones and internet access will drive this growth, making OTT platforms a primary source of entertainment for many viewers.

Fractional Distillation
- 2. Fractional distillation is one of the widely used distillation technique used in R & D sector because of its efficiency and accuracy. It is more efficient in separating ideal solutions into their pure components than the traitional method of distillation
- 3. Heat Source for e.g a hot plate with a bath A distillation flask (preferably a round-bottom flask) A collecting flask ( conical shaped or round-bottom flask) Fractionating column ( elongated glass ware for solvent cooling) Distillation head Thermometer (to measure the temperature of the solvent placed) Condenser Vaccumed Adapter (to carry out distillations under reduced pressure) Boiling chips or Anti-bumping granules Rubber bungs, unless laboratory glassware with ground
- 4. Purification of water and ethanol mixture is usually carried in the research labs The separation of ethanol and water is based upon the different boiling point of the two solvent. Ethanol require boiling point of 78.5 ° water boils at a temperature of 100 degree Celsius Boiling the mixture in fractional distillation column separates the liquid into its respective components Usaully 96% of pure ethanol is extracted by fractional distillation technique
- 5. Similarly various other Azeotropic mixture can be extracted using fractional distillation technique such as a mixture of cyclohexane and toluene, etc. Fractional Distillation has gained a wider application in scientific research laboratories and in industrial application to extract the pure form of solvent from its solvent mixture
