A removal process consisting of absorption‚ desorption‚ heat exchangers and auxiliary equipment is shown in Figure 10. Absorption is traditionally performed in a column with plates‚ random packing or structured packing. CO2 containing gas flows upwards and the absorption liquid flows downwards. The solvent (rich amine) is pumped further through a heat exchanger to a separation column. The absorbed CO2 is regenerated in a separation (stripper) column. Heat is added to the reboiler and a condenser

Gas chromatography (GC) is a chromatography technique where the separation of individual components (analytes) from a sample relies on their differing distribution between a mobile and stationary phase. The mobile phase carries the analytes through the stationary phase. In GC‚ it’s an inert gas (usually helium or nitrogen). The gas must be inert‚ so it won’t react with the sample to give a false reading. The stationary phase is a substance fixed in place to which the sample adsorbs because

Undoped and Ce doped ZnO thin films were prepared by the sol-gel process. Zinc acetate dehydrate was dissolved in a mixture of absolute ethanol and monoethanolamine (MEA) yielding to a precursor concentration of 0.4 M .The MEA to zinc acetate molar ratio was set to 1. For doped films‚ cerium nitrate was added to the mixture with an atomic percentage fixed at 0.1‚ 0.3‚ 0.5‚ 0.7‚ and 0.9 at.% Ce‚ respectively. The resulting sols were magnetically stirred at 60°C for 1 hour and then aged at room temperature

Trimyristin is an ester with the chemical formula C45H86O6 that can be isolated from the common spice nutmeg. The seed of the evergreen trees in the genus Myristica Fragrans is what nutmeg is obtained from. Trimyristin is the triglyceride of myristic acid also known as saturated fat (3). The phase of trimyristin is solid and is only found soluble in dichloromethane‚ chloroform‚ ether‚ benzene‚ and ethanol (1). Only twenty to twenty-five percent of trimyristin makes up the mass of nutmeg and it

Unit Project Documenting the Scientific Method Separating Mixtures Project Separating Mixtures: How can you separate salt water to make pure and drinkable fresh water? Design and build a device to separate a mixture of salt water into its components. For example‚ what device could you build to get the most drinkable water from salt water if you were on a stranded island in the middle of the ocean? Gather data on the amount of water collected and the purity of the water‚ which can

Preparation In a dry round bottom flask‚ 1.5mL of cyclohexanone was added with 5mL of methanol. The solution was cooled in an ice bath for 3 minutes after which 0.2g of sodium borohydride was measured and added to the solution. Upon mixing‚ a gas was formed (bubbles). The round bottom flask was removed from the ice bath and placed at room temperature. After 10 minutes at room temperature‚ 5.0mL of 3M NaOH and 2.0mL of distilled water was added to the solution.

Anthony Young Partner: Nick Dale TA: Alehkya 6/8/15 Isolation of Trimyristin from Nutmeg and Preparation of Myristic Acid from Trimyristin by Hydrolysis. Introduction In this experiment‚ trimyristin will be isolated from the nutmeg by extraction‚ and then used to prepare myristic acid by hydrolysis. The isolation of a substance from a natural product is a common technique used nowadays. Usually‚ the isolation is a complex procedure and requires a lot of steps and preparation. For this experiment

Part 1 dilutions participated as a trail run to gather around the “full enzyme” that was used for the other parts of the experiment. Part 2 readings were in the time span of 10 minutes and the final results show a spontaneous increase in the first minutes of the absorbance readings. They then showed a steady reading towards the end of timing. The amount of enzyme is decreasing as the dilution occurred. The activity it catalyzes measures the amount of enzyme present in the reaction (Introduction to

Procedure 2.0 g of Mo(CO)6 and 10 mL of mesitylene were added into a 50-mL round bottom flask along with a small magnetic stir bar. A 30-cm reflux condenser was attached to the round bottom flask and a gas inlet was then connected to the condenser and to the bubbler. Since Mo(CO)6 and the product tends to react with oxygen at high temperatures this reaction must take place in an inert atmosphere. Therefore‚ the gas inlet was connected at the top of the condenser to a nitrogen source and was flushed
