Advantages Of Thermal Membrane Distillation
INTRODUCTION
Water makes up 71% of Earth surface. This water is not fresh or drinking water. The limited supplied of fresh water coupled with the over use of fresh water demands for the sustainable development and cost effective strategies of water management [3]. Water desalination or the purification is an important auxiliary process in all thermal generation plant. The selection of the water treatment process is dependent upon the final water quality and volume of the water treated. Membrane based technologies are important component in such systems as they have been developed to meet the needs of the power generation industries.
Thermal membrane Distillation is one of the developing promising separation technologies. It is a new technology that lies at the interface between thermal and membrane technologies. Thermal membrane distillation is an isothermal separation process where partial evaporation of water is created by heating up the feed solution to be distilled to some moderate temperature [5]. It involves the heat and mass transfer through a hydrophobic semipermeable membrane through the use of thermal energy to bring about the separation of a feed streams- a permeate and reject stream.
As the name indicates, Thermal membrane Distillation has the similarities to both membrane separation and distillation [2]. Both thermal membrane distillation and conventional distillation are both rely on the vapor-liquid equilibrium for separation and these both processes require

Miniscale Fractional Unpacked Distillation Lab Report
1481 Words | 6 PagesFeras Kaid Chem 2415-43 TA: Rio Assessment 1 Conclusion In this lab, there were 4 different distillations that were performed each with the same end goal to separate the two different organic compounds, cyclohexane and toluene. We used the boiling points of the two compounds to separate them using the following 4 techniques: microscale simple distillation, miniscale simple distillation, miniscale fractional packed distillation, and miniscale fractional unpacked distillation. The three different miniscale distillations were used to predict the accuracy of the distillation by comparing them to one other. The most accurate of the three distillations is the miniscale fractional packed distillation because this type uses a Vigreux column instead

1286 Words | 6 PagesFiltering, evaporating, centrifuging, and decanting something will only physically change it. Chromatography is used to separate different parts of a solution so that it can be identified. It can work because different substances have different attractions to things. Distillation can separate substances, such as salt water, as long as it has different boiling points. It can even be used to purify salt water but it is not cost efficient or energy efficient so it is not suitable for everyday use.
Bottled Water Research Paper
513 Words | 3 PagesJulie is typical twenty-five year-old Hispanic woman that grew up in a household where drinking water from the tap was frowned upon. Now, as an adult, Julie drinks about five water bottles per day, which adds up to 150 water bottles a month, or a grand total of 1,800 water bottles per year. Her water bottle of choice – Dasani Purified Water – costs an average of $4.99 per twenty-four pack, or around $0.20 per bottle, at her local Wal-Mart. This means that Julie, by herself, annually consumes around 74 twenty-four packs of bottled water. In other words, she spends $369.26 on drinking bottled water every year1.
Why Is Tap Water Better Than Bottled Water
602 Words | 3 PagesIn recent years, the tap water versus bottled water debate has been widely discussed. Many follow the tap water train more than bottled water due to cost, taste, and safety. Most people will spend more money every year purchasing bottled water because of the taste. The funny thing that most people do not realize is that 25% of bottled water is tap water (Postman). Most people have made the switch to tap water from bottled water, because tap water is cheaper, safer, and it tastes just as good, if not the same, as bottled water.

Distillation And Purification Of Liquids Lab Report
742 Words | 3 PagesIn a simple distillation, the solution is brought to a boil and the vapours rise into a stillhead that directs them into a condenser. The vapour is condensed to the liquid phase and collected. This method works well for solutions that are composed of liquids with vastly different boiling points. However, if the liquids are similar in boiling points, fractional distillation is the preferred method of separation. In this technique, vapours are forced to pass through a fractional distillation column before reaching the stillhead.

They are two major finding in this experiment. he first finding was the point at which the raw petroleum is heated to the point of boiling, at 275 0C, the gas and kerosene oil are refined, however the oil (lubricant ) stays as an unrefined feature oil.

Distillation Lab Report
1300 Words | 6 PagesAbstract — This experiment was conducted to familiarize the students with the procedures regarding distillation—to be more precise, the separation of ethanol from an alcoholic beverage—using a distillation set-up consisting of boiling chips, a Bunsen burner, a condenser, a thermometer and several other materials. In the end, it was discovered that one may actually separate a homogeneous mixture, given that the components of said mixture differ in volatility and that they utilize a complete distillation set-up and follow laboratory safety rules and regulations. Keywords — Matter, homogeneous and hetereogeneous mixtures, distillation, volatility, boiling point I. INTRODUCTION There are typically two categories of matter, these are pure substances
Methanol Lab Report
1257 Words | 6 PagesIn this experiment, extraction was used as a separation technique to separate the acid, base, and neutral compounds. In extraction, two immiscible solvents with opposite polarities are used to dissolve different parts of the solute with different polarities, so they form two distinct liquid layers. In this experiment, methanol, an organic solvent, and an aqueous solution were used as the two immiscible solvents. The extraction solvent must also be capable of dissolving one of the mixture components. While initially it seems as though methanol, an organic solvent would be incapable of dissolving a polar acid or base, the conjugate of the acidic and basic compound will dissolve in methanol.
