EXHIBIT 5-13 Typical Process Vessel Sketch for a Horizontal Drum... 

Drum dimensions, nozzle sizes, and, if required, internals are shown on the process vessel sketch furnished by process engineering and included in the process... 

For example, the platform elevations shown on the process vessel sketch in Exhibit 10-3S> are the minimum requirements for instrument, valve, and maintenance access. Exhibit 10-50 displays a platform arrangement for the tower using the information in Exhibit 10-39 and the guidelines in this chapter. 

As far as the actual use of these expressions in their most general form, Eqs. (36) and (37), probably the only case which need be considered is that represented by the bottom sketch of Table II. Here measurements are taken only on either side of the test section. This type of measurement could be used to find the dispersion characteristics of a process vessel in a plant where no means are available for inserting a probe inside the vessel. With these equations, measurements need be taken only on either side of the text section. 

An ECT system is composed of three basic components (1) a capacitance sensor, (2) a data acquisition system, and (3) a computer system for reconstruction and viewing. Figure 1 is a sketch of the ECT system with all three components (Warsito and Fan, 2003). The capacitance sensor is made of nr capacitance electrodes distributed around the wall of the process vessel. The ne capacitance electrodes provide up to ne(ne—1)/2 combinations of independent capacitance measurements between the electrode pairs. The capacitance measurements are related to the local dielectric constant (permittivity) filling the process vessel between electrode pairs (Figure 2) (Warsito and Fan, 2001b). The relation between the electric potential and the permittivity distributions follows Poisson equation shown in Equation (1). 

Figure 17.21. Some recent designs of ammonia synthesis converters, (a) Principle of the autothermal ammonia synthesis reactor. Flow is downwards along the wall to keep it cool, up through tubes imbedded in the catalyst, down through the catalyst, through the effluent-influent exchanger and out. (b) Radial flow converter with capacities to l tons/day Haldor Topsoe Co., Hellerup, Denmark), (c) Horizontal three-bed converter and detail of the catalyst cartridge. Without the exchanger the dimensions are 8 x 85 ft, pressure 170 atm, capacity to 2000 tons/day (Pullman Kellogg), (d) Vessel sketch, typical temperature profile and typical data of the ICI quench-type converter. The process gas follows a path like that of part (a) of this figure. Quench is supplied at two points (Imperial Chemical Industries).

Formulation of multi-component emulsions and mixtures are of interest in chemical and industrial processes (Vilar, 2008 Vilar et al., 2008). Standard stirred tank reactors (STR) and oscillatory baffled reactors (OBR) are traditional methods for the formulation of liquid-liquid mixtures and liquid-solid emulsions. Compared with STR, oscillatory baffled reactors provide more homogeneous conditions and uniform mixing with a relatively lower shear rate (Gaidhani et al., 2005 Harrison and Mackley, 1992 Ni et al., 2000). Figure 17 is a sketch of a typical oscillatory baffled reactor. It consists of the reactor vessel, orifice plate baffles, and an oscillatory movement part. The orifice plate baffles play an important role in the OBR for the vertex generation in the flow vessels as well as the radial velocities of the emulsions and mixtures. They are equally spaced in the vessel with a free area in the center of each baffle... 

Reactor design. TCC reactors are cylindrical steel vessels 11 to 16 ft. in diameter with catalyst beds 8 to 35 ft. deep a sketch is shown in Figure 12. The quantity of catalyst in the reactor at all times is typically about eijual to the weight of oil charged each hour i.e., the space velocity is about unity. The reactors are insulated on the outside reactors to be used for processing corrosive stocks are alloy-lined. 

In this case, too, we first draw a sketch of the apparatus. Fig. 1.35. We consider an arbitrary stirrer in a baffled vessel filled with a liquid. Then we facilitate our work by proceeding systematically For this, the influencing parameters will be devided into three groups geometrical, material and process related parameters ... 

This paper is concerned with an analysis and experimental measurement of the thermal response of the vessel wall during the process of emptying for the cases of an uninsulated vessel exchanging heat with the ambient and a vessel having a constant input heat flux imposed on its exterior surface. Also considered is the condensation of the pressurizing gas on the liquid—gas interface. A sketch of the experimental test vessel is shown in Fig. 1.
