CHG 3111 Unit Operation Gas-Liquid Separation Text Book: Chapter 10 Separation Processes Introduction: Many chemical and biological processes occur as a mixtures of different phases‚ gas‚ liquid and solid. To separate or remove one or more of the components from its original mixture‚ it must be contacted with another phase. The two phase pair can be gas-liquid‚ liquid-liquid or liquid-solid. When different phases are brought into contact‚ a solute or solutes can diffuse from on phase to the

The Separation of Powers devised by the framers of the Constitution was designed to do one primary thing: to prevent the majority from ruling with an iron fist. Based on their experience‚ the framers shied away from giving any branch of the new government too much power.. This is why they implemented the separation of powers and also the checks and balances system. Three branches are created in the Constitution. The Legislative‚ composed of the House and Senate‚ is set up in Article 1. The Executive

Seperatation Technqiues of Sand/Salt/Water Mixture Most of the material that are encountered in everyday life are not pure substances. Materials ranging from cement‚ food and ink are formed from physical combinations of various substances called mixtures. A mixture is a type of material that consists of two or more different substances that are not chemically combined. All mixtures can be separated back into its original state except for those that undergo irreversible change. A mixture can take

The concept of separation is a key theme of Kindertransport‚ and is explored in a plethora of ways throughout the play. As the Kindertransport was designed to rescue children from persecution in wartime Germany‚ it separated them not only from the violence and suffering of the Holocaust but also the love and care of their parents‚ a concept presented through all characters and in all stages of the play. The application of a “label” to Eva designates her as a minority‚ separating her from the general

Objective In this experiment we would be ascertaining the percentage content of ethanol in 3 samples (spirit‚ wine and a beer). We would be comparing the concentration of ethanol to that of 25%propanol which would act as an internal standard. Method To set up the standards for a calibration curve we would make solutions of different concentrations of ethanol. Using a 25cm3 volumetric flask we would put 10cm3 of 25% Propanol into each one which would act as an internal standard. We would

3418-2 March 3‚ 2011 Theoretical Background- The fluorene and fluorenone mixture was separated by first dissolving the mixture in heptane. Since “like dissolves like”‚ fluorene dissolves with the non-polar heptane and the polar fluorenone dissolves in the polar ethyl acetate solvent. This phenomenon was illustrated in class before the experiment‚ when it was pointed out why water will not dissolve fluorene‚ fluorenone‚ or transstilbene as readily as a nonpolar solvent such as heptane

This technique is important in organic chemistry because certain experiments may require the separation of compounds in solution to be used for chemical synthesis and/or analysis of a particular desired product by isolating it. Fluorene is to be separated from 9-fluorenone using the technique of column chromatography. The success of separation and purity is determined with analyzation technique thin layer chromatography and measuring the melting temperatures. The theory of column chromatography is
