Separation equipment nozzle separator

Monomer emulsions are prepared in separate stainless steel preemulsification tanks, which are usually equipped with an agitator, manometer level gauge, cooling cods, temperature recorder, mpture disk, flame arrester, and various nozzles for charging the ingredients. Monomer emulsions maybe charged in one shot to the reactor or, more commonly, fed continuously throughout the polymerization. 

Other suggestions that address gas flow deviation include a retrofit of the stator-nozzle assembly or replacing rotors with shorter blades. However, it is easier to increase volume flow by lowering inlet pressure. Increased capacity of the third-stage separator and the auxiliary equipment avoids the possibility that excess catalyst will pass through the equipment. 

A typical non-condensible blowdown drum and its associated equipment and headers are illustrated in Figure 1. A single blowdown drum may be used for more than one process unit, if economically attractive. However, when this is done, all units served by it must be shut down in order to take the drum out of service, unless cross connections are made to another system of adequate capacity. Normally all closed safety valve discharges are combined into one header entering the drum, although separate headers and inlet nozzles are acceptable if economically advantageous. The following releases are also normally routed into the safety valve header ... 

Note 4 Surface preparation for painting is often analysed separately as it may typically form one-third of the total cost. Poor surface preparation can more than halve the life expectancy of a coating (and add over 100% to the total life cost) but save less than 20% of the total capital cost. Correct choice of blasting equipment (e.g. nozzle size, grade of abrasive) can save up to half the surface preparation cost. 

Suitable feeds to a spray dryer are solutions or pumpable pastes and slurries. Such a material is atomized in a nozzle or spray wheel, contacted with heated air or flue gas and conveyed out of the equipment with a pneumatic or mechanical type of conveyor. Collection of fines with a cyclone separator or filter is a major aspect of spray dryer operation. Typical equipment arrangements and flow patterns are shown in Figure 9.14. 

A 2-liter stainless steel vessel, partially filled with I2 crystals, was connected directly to the secondary He feed supply line of a supersonic chemical laser. A complete description is given in a separate paper.- The laser cavity had viewing windows on top and bottom so that the nozzle array could be viewed in a direction perpendicular to the optical axis. The pump laser was a Spectra-Physics Model 170-03 Ar+ laser equipped with an intracavity etalon. 

Every low-pressure, closed-top tank with an overflow line should be equipped with some type of device to prevent collapse from an overfilling operation. A large open nozzle, a high-level alarm and/or shutdown system, vacuum breakers or separate vent lines are some appropriate safeguards. 

Following the biological waste water purification, an easy separation of activated sludge flocks can be achieved by flotation. To facilitate this separation, the flotation cell is subdivided into two parts, each having equal superficial areas, Fig. 58. The inner cylindrical vessel serves as the aeration chamber, this being equipped with the forementioned funnel-shaped nozzle. Here, particles are brought into intimate con-... 

The equipment consists of a high pressure part where the highly compressible medium/gas is dissolved in the substance which has to be micronised. The second part of the equipment is the expansion device, where the gas saturated solution is rapidly depressurized through a nozzle into a spray tower where the particles with a diameter >10 pm are separated. 

Spray Scrubbers. Spray scrubbers consist of an empty cylindrical chamber in which dust-laden air is contacted with water from spray nozzles, as shown in Figure 20.6(b). The dust-laden air enters the tower near the bottom and passes upward through the water spray. This type of equipment is similar to the spray towers used in mass transfer operations. Proper water distribution can be a problem, so multiple banks of spray nozzles mounted on a manifold produce better air-water contact. The spray knocks down the dust that leaves the bottom of the unit as a dust-water mixture. An entrainment separator is mounted in the upper part of the chamber to reduce the potential spray carryover into the exiting gas stream. 

The burner of type Oilon Lenox GRT-5L is a mixing burner for oil and gas combustion in boilers. The burner was equipped with the dual fuel lance, which enables the use of two different liquid fuels either separately or simultaneously. Heavy fuel oil (PORL 180) was used as support and start up fuel. A KM-nozzle type...
