Liquid-liquid extraction

The results found in the collated table supports the hypothesis, however, it was not as accurate as expected. From observation of the collated results, it can be seen that the greatest froth volume is found at 30oC, rather than the predicted optimum temperature of 39oC. Errors within the individual group results, concluded that the both 10oC and 20oC were wrong due to the vast froth volumes. For a smaller amount of catalase, this would result in a smaller froth volume, conversely, with a greater…

in such a manner that prevented emerged bubbles that could have formed disrupting test accuracy. o Temperature of the liquid was collected once the fluid was in the cylinder. 3. Dropped into the cylinder was a Glass (Dark) ball then a Steel (Silver) ball twice for a total of four trials. o Each ball was fished out smoothly from the oil to be removed with a hook utensil. o The liquid was drained out about halfway back into the measuring cup at a slightly incline manner pouring slowly. 4. Slow…

Paintball is a game that shoots out markers or paintballs, that when they hit, the markers explode causing a paint mark on a person, a piece of cover, and trees.Paintball is also a game where many people do different types of games like capture the flag to different battle scenarios. Before paintball was a game paintballs was used to mark cattle for shipping purposes. Many people play this game with pump guns. These guns have an air pump attached and also a hopper.The hopper is the top piece of…

of 3M HCl was added and swirled into the solution. The top of the 25-mL flask was capped and the two liquid were mixed in a thorough manner. Ventilation was required after every few seconds. After letting the solution sit for a while and letting the liquid layers separate,…

CHAPTER 1: BACKGROUND 1.1 ENHANCED OIL RECOVERY Oil production is differentiated into three stages: primary, secondary and tertiary, which is also known as Enhanced Oil Recovery (EOR). Primary oil recovery is restricted to hydrocarbons that naturally produced to the surface, or those that utilization artificial lifts, for example, pump jacks. The secondary recovery utilizes water and gas injection, dislodging the oil and driving it to the surface. US Department of Energy stated that by using…

A drill pipe non-return valve (NRV) is essential in MPD operations. A U-tube analogy demonstrates that any positive unbalance in the annulus will result in forcing fluid up the drill pipe. [4] Referred to as a float, the NRV is usually driven by a piston. During circulation, drilling fluid forces the valve open against the spring. When pumps are off the valve is closed through a combination of the spring and wellbore pressure. [2] Figure 2.7c Rig layout for MPD operations (KCA Deutag Source…

Therefore, the three-dimensional unsteady heat conduction differential equation is: where T (x, t) is the temperature of the spot x at the time t and is also the coefficient of thermal diffusivity used to measure the heat transfer and storage ability of the material, which varies with temperature and position. Equation (5) gives the form of three-dimensional heat transfer function. It is generally difficult to find the analytical solution because of the complexity of the actual solution…

HOW JCB MACHINE WORKS The Basic Idea of Hydraulics: The basic idea behind any hydraulic system is very simple. Force that is applied at one point is transmitted to another point using an incompressible fluid. The fluid is almost always an oil of some sort. The force is almost always multiplied in the process. If two pistons fit into two glass cylinders fitted with oil and connected to one another with an oil-filled pipe. If you apply a downward force to one piston(suppose the left one), then…

The experiment of fluidization in packed column was determined by using air as the conveying media. The fluidized bed is when the air make the solid to behave like a fluid. For this experiment, two columns are use which one column are filled with sand and the other one filled with aluminum oxide. The bed height of aluminum oxide is 100 mm and have a particle size about 250 micron (mesh 60). The minimum fluidization velocity is used to determine the pressure drop. As mentioned above, when the…

3.3 Tribological properties of Cr-B-C-N coatings in artificial seawater Fig.10 shows the friction behaviors and the mean-steady friction coefficients of Cr-B-C-N coatings sliding against SiC balls in artificial seawater. As seen in Fig.10a, it is clear that the CrCN coatings showed higher friction coefficient than other coatings during the tribo-test in artificial seawater. The initial friction coefficient of CrCN coatings was 0.17, while that of CrBCN coatings ranged between 0.14 and 0.15. For…
