The organic and aqueous phases are prepared in separate tanks before transferring to the reaction ketde. In the manufacture of a styrenic copolymer, predeterrnined amounts of styrene (1) and divinylbenzene (2) are mixed together in the organic phase tank. Styrene is the principal constituent, and is usually about 90—95 wt % of the formulation. The other 5—10% is DVB. It is required to link chains of linear polystyrene together as polymerization proceeds. DVB is referred to as a cross-linker. Without it, functionalized polystyrene would be much too soluble to perform as an ion-exchange resin. Ethylene—methacrylate [97-90-5] and to a lesser degree trivinylbenzene [1322-23-2] are occasionally used as substitutes for DVB. 

The aqueous phase into which the monomer mix is dispersed is also prepared in a separate tank before transferring to the copolymerization ketde. It contains a catalyst, such as benzoyl peroxide [94-36-0], to initiate and sustain the polymerization reaction, and chemicals that aid in stabilizing the emulsion after the desired degree of dispersion is achieved. Careful adherence to predeterrnined reaction time and temperature profiles for each copolymer formulation is necessary to assure good physical durabiHty of the final ion-exchange product.

Redox flow batteries, under development since the early 1970s, are stUl of interest primarily for utility load leveling applications (77). Such a battery is shown schematically in Figure 5. Unlike other batteries, the active materials are not contained within the battery itself but are stored in separate tanks. The reactants each flow into a half-ceU separated one from the other by a selective membrane. An oxidation and reduction electrochemical reaction occurs in each half-ceU to generate current. Examples of this technology include the iron—chromium, Fe—Cr, battery (79) and the vanadium redox cell (80). 

Many platiag plants use electrocleaners both anodicaHy and cathodicaHy through the use of reversing switches or ia two separate tanks. Not all anionic surfactants do well ia cathodic cleaning. Proprietary electrocleaners are commonly used and highly recommended. 

Low-temperatiire liquefied gases are shipped in special ships with insulation between the niiU ana an inner tank. Poisonous materials are shipped in separate tanks built into the ship. This prevents tank leakage from contaminating harbors. Separate tanks are also used to transport pressurized gases. 

Oil-water mixmres and emulsions, e.g., from separators, tank bottoms, ballast water, etc. Heating of such materials is often necessary to separate oil and water. 

Flash chamber A chamber provided to al low the burning of a flammable gas in a process. In a refrigeration system, it is the separating tank between the expansion valve and the evaporator. 

A liquid propellant consists of two liquid chemicals, fuel and oxidizer, which arc delivered from separate tanks into the cninbtistinii chamher of a liquid propellant rocket engine (LPRE). 

The knock-oul drums or separator tanks/pots can be designed using the techniques offered in the chapter on Mechanical Separadon, and will not be repeated here. API-RP 521 [13] specifies 20-30 minutes holdup liquid capacity from relief devices plus a vapor space for dropout and a drain volume.

The large scale of slurry ice storage system is installed in Kyoto station building. The building of 237,689 m2 floor area is air conditioned with 4 absorption chillers of 5,830 kW and slurry ice tank of 1,700 m3. Sub cooled water is projected into tube shape inlet where ice is made by release from sub cooling state. Slurry ice is conveyed to separate tanks through a pipe (Figure 192). 

In contrast, a drip tank recovers process chemicals by collecting dragout into a separate tank, from which it can be returned to the process as needed. 

The washing could be done in the reactor or in separate tanks. In the proposed scheme, it is done in separate tanks. These wash tanks also provide the feed to the continuous purification system that follows. A continuous purification system is used because usually continuous processing is cheaper than batch processing. Thus, the washtanks serve also as holdup tanks. Since the wash tanks are much less expensive thia the reactors (see Chapter 9), it is expected that money will be saved by reducing fnc time the material spends in the reactors, and hence the number of reactors needed. 

To tempo- this water assume that 30% of the water must be heated to 14deionized water, this will be done in a separate tank. This tank will be designed to have a 0.5 hr holdup. The vessel will have steam coils to heat the water. Assume the coils occupy 10% of the space, and the tank is 90% full. 

Pumps provide pressurized pumping from the well to the storage/separation tank in addition to suction of fluids from the wells. 

The dimerization (Aldol condensation) takes place at temperatures of 175—250°F in the presence of a dilute solution of sodium hydroxide. After the reaction, the mixture is passed to a separator tank where the dimer is separated then sent to a reactor to be hydrogenated over a nickel catalyst. Reaction conditions have temperatures of 300°F and 2500 psi. Distillation of the effluent gives purified 2-EH in 95% yield. 

After the polymerization step, the reaction mixture is fed to a heated separation tank where the unreacted propylene is flashed off and recycled. The polymer slurry is then washed with alcohol to deactivate and remove the catalyst and the atactic polymer (the bad stuff.) Centrifuging the slurry removes the diluent from the isotactic PP (the good stuff.) The product is washed with acetone, dried, and stabilized with suitable additives. It is sold as a powder or can be pelletized into granules. 

Good donor cars. The Camaro has a computer on board, I have one with a v6 vortec. The Mustang will be the better bet as the car won t need to be modified. Just print off the diagram and use the parts listed. Don t change the fuel tank or exhaust at this point in time. Just hook a hose to the fuel pump from a separate tank of water, you won t have to mount anything on the car either. 

Ion exchange resins are normally reused. The spent enzyme on the carrier particles is washed away with a salt or sodium hydroxide solution. After washing with water, fresh enzyme can be adsorbed onto the particles. Regeneration can be carried out in the colunrn or in a separate tank. 

In a separate tank, properly cleaned, boil at least 65 mL of purified water for at least 15 minutes, cool while bubbling C02 into it, and hold at 30°C and adjust pH in the range 3.1 to 3.3.

Flocculation should be performed in a separate tank or compartment of a tank from neutralization. Organic electrolyte is added to aid in the agglomeration process. 

The emulsion of nitroglycerine is allowed to run into separating tanks in which the components are separated into two layers by an upward flow of water. Nitroglycerine is discharged from the bottom of the tank and passes to the filters.
