Aspects of Rotary Vacuum Filter Design and Performance

The separator separates oil from the condensed water. Since total volume of water condensed will be larger than the quantity of the oil, it is necessary to remove the oil continuously (Hunter, 2009). The condensate flows from the condenser into the separator where the water and oil will be separated automatically based on their difference in specific gravities. Florentine flask is one of the commonly used separator (Mohamed, 2005). The two liquids will form two separate layers, where the lighter oil will float on top of the water. The oil will sinks to the bottom whenever its specific gravity is more than 1.0 (Guenther, 1948).

When the crude product is transferred to a separatory funnel, it is washed with 10 ml of water. When the solution forms two layers, the bottom aqueous layer is disposed of.

The system must exhibit no visible emissions to the outside air. The owner or operator may alternatively use air cleaning and shall, for fabric filter collection devices installed after January 10, 1989, provide for easy inspection for faulty bags. After January 10, 1989, if the use of a fabric filter creates a fire or explosion hazard, or the Director determines a fabric filter is not feasible, the Director may authorize as a substitute the use of wet collectors designed to operate with a unit contacting energy of at least 9.95 kilopascals (or 40 inches water gage pressure), or use a HEPA filter that is certified to be at least 99.97 percent efficient for 0.3 micron particles. The Director may authorize the use of filtering equipment other than described in Reg. 21.901(F) if the owner or operator demonstrates to the Directors satisfaction that it is equivalent to the described equipment in filtering particulate asbestos material. A copy of any authorization from the Director must be retained at the

Working in the hood or a designated work area, add about 1 mL of ethyl alcohol to a clean evaporating dish. Place the evaporating dish on a heat- resistant pad.

Next rinse the funnel with cleaning solvent to ensure all impurities in the solvent are removed.

The purpose of this experiment is to become familiar with the separation of mixtures of solid and learn separation techniques based on the chemical properties of a substance.

alcohol (2-methyl-2-butanol, MW _ 88.2, d _ 0.805 g/mL) and 25 mL of concentrated hydrochloric acid (d _ 1.18 g/mL). Do not stopper the funnel. Gently swirl the mixture in the separatory funnel for about 1 minute. After this period of swirling, stopper the separatory funnel and carefully invert it. Without shaking the separatory funnel, immediately open

The pipette was used to transfer 8 mL of the 0.5 molarity solution into the graduated cylinder. Distilled water was added to raise the bottom of the meniscus to the 20.0 mL line and the solution was transferred into the beaker after it was rinsed with the solution. The pipette was used to take a small quantity of the solution and rinse and then fill a test tube with the solution. The amount of 0.2 molarity solution needed to create 20.0 mL of 0.1 molarity solution was calculated as 10.0 mL. The pipette was used to transfer 10.0 mL of 0.2 molarity solution into the graduated cylinder and distilled water added until the bottom of the meniscus reached the 20.0 mL line. The solution was transferred to the rinsed beaker and then a portion placed into a test tube that had been rinsed with the solution. The amount of 0.1 molarity solution required to create 20.0 mL of 0.05 molarity solution was calculated to be 10.0 mL. The pipette was used to transfer 10.0 mL of 0.2 molarity solution into the graduated cylinder and distilled water added until the bottom of the meniscus reached the 20.0 mL line. The solution was then placed into a beaker that had been rinsed with the solution and then into a rinsed test

2) Rinse the solid with about 30 mL of distilled water and decant the liquid from the solid. It is critical that as little solid as possible is lost during this process. Repeat the rinsing two or three times.

Stearyl alcohol prevents from end-mixture to separate back into its original oil and liquid components.

The purpose of the fluid flow meters experiment was to determine the operating characteristics of the Venturi and orifice meters. The purpose of the tray hydraulics experiment was to study the vapor and liquid tray hydraulics parameters for sieve, or perforated, trays in a distillation column. By performing experiments based on theory and comparing results to literature values, the objectives of this experiment can be achieved.

If necessary the centrifuge can also be used to further separate the two layers. A final means of drying the ester product is the addition of granular sodium sulfate.

4. Prepare a vacuum filtration apparatus using a buchner funnel. Obtain one filter paper for each one of your samples, weigh them and record their mass in your notebook (label them with a pencil to be able to differentiate them later).

It is of critical importance that Sealed Air address the threat presented by the growth of the uncoated bubble segment, which outstrips that of coated bubble in the US and Europe. Serving the lower end of the market is consistent with the company's customer-focused market leadership and provides distributors with a full-line of product. In addition, there appear to be a number of segments that may be serviced by uncoated bubble (e.g., the ½ in. GAFCEL bubble is comparable to Sealed Air's ST/SD-120 for light loads) . Further, uncoated bubble would require minimal capital as
