Fig. 4.18B and C show the cases of gas extraction and gas addition. Note that because the extraction rate is very high, an equal amount of gas is taken firom the outlet (top) of the system, as is fed via the inlet (bottom). Since the simulation domain is higher than actually shown in Fig. 4.18, the flow from the top already has a parabolic flow profile, while the gas entering from the... 

The simplest type of centrifugal device is the cyclone separator (Fig. 3.4), which consists of a vertical cylinder with a conical bottom. The centrifugal force is generated by the fluid motion. The mixture enters in a tangential inlet near the top, and the rotating motion so created develops centrifugal force which throws the particles radially toward the wall. 

Wastewater leaves the process from the bottom of the second column and the decanter of the azeotropic distillation column. Although both these streams are essentially pure water, they will nevertheless contain small quantities of organics and must be treated before final discharge. This treatment can be avoided altogether by recycling the wastewater to the reactor inlet to substitute part of the freshwater feed (see Fig. 10.36). 

Hydrocylones have become common on offshore facilities and rely on centrifugal force to separate light oil particles from the heavier water phase. As the inlet stream is centrifuged oil particles move to the centre of the cyclone, coalesce and are drawn off upwards, while the heavier water is taken out at the bottom. 

Pour the mixture into a 500 ml. flask fitted with a steam-distillation head, and with a steam-inlet tube reaching almost to the bottom of the flask. First distil off the benzene in steam. Then place the flask in an oil-bath heated to 165-170 ", and continue the steam-distillation (2-3 hours). The /)-bromobiphenyl passes over and forms orange crystals in the water-condenser therefore run the water out of the condenser for a short while from time to time to melt the orange deposit and allow it to run into the receiver containing the distilled water. 

Method 1. Fit a 500-ml. three-necked flask with a thermometer (the bulb of which is within 2 cm. of the bottom), and inlet tube extending to the bottom of the flask, and a double surface condenser. Use old ... 

Ayparatue. 2-1 three-necked round-bottomed flask with a dropping funnel, combined with a gas inlet, a mechanical stirrer and a thermometer, combined with a gas outlet. 

Apparatus-. 1-1 three-necked, round-bottomed flask with a thermometer+gas outlet, a stirrer and a gas inlet. During the experiment a slow stream of nitrogen was passed through the flask. A Dewar flask containing liquid nitrogen (note 1) was used as a cooling bath. 

Apparatus 3-1 round-bottomed three-necked flask with a combination of dropping funnel and gas inlet tube, reaching 1 cm beneath the surface of the NH3, stirrer and a combination of thermometer and vent (see Chapter I, Fig. 1). 

Apparatus 200-ml round-bottomed, three-necked flask provided with a gas inlet, a thermometer and a gas outlet magnetic stirring. 

Apparatus. 500-ml round-bottomed, three-necked flask with a gas inlet tube, thermometer and a gas outlet for the preparation of chlorotetrahydropyran 1-1 four--necked, round-bottomed flask with a gas inlet tube, a dropping funnel, a mechanical stirrer and a thermometer, combined with a gas outlet for the preparation of HC=CMgBr and its reaction with chlorotetrahydropyran 1-1 three-necked, round--bottomed flask with a dropping funnel, combined with a gas inlet, a mechanical Stirrer and a thermometer, combined with a gas outlet for the conversion into the allenic alcohol. 

Apparatus 100-ml two-necked, round-bottomed flask, provided with a gas inlet and a reflux condenser. 

Apparatus. 2-1 three-necked, round-bottomed flask, provided with a gas inlet tube, a gas-tight mechanical stirrer and a gas outlet two washing bottles filled with paraffin oil were connected with the gas inlet and outlet. 

The commercial appHcation of this concept (68) is portrayed ia Figure 8, which shows the adsorbent as a stationary bed. A Hquid circulating pump is provided to pump Hquid from the bottom outiet to the top inlet of the adsorbent chamber. A fluid-directing device known as a rotary valve (69,70) is provided. The rotary valve functions on the same principle as a multiport stopcock in directing each of several streams to different lines. At the right-hand face of the valve, the four streams to and from the process are continuously fed and withdrawn. At the left-hand face of the valve, a number of lines are coimected that terminate in distributors within the adsorbent bed.
