A number of simple equations have been developed for the prediction of the areal sulfide production rate, ra, in pressure pipes (Table 6.1 and Figure 6.4). All equations take into consideration that the sulfide generation is affected by... 

Next correct HETS for column diameter from Equation 6.32.9. Because D is less than 30 in (0.762 m), select a standard pipe size. From piping tables [66], select a Schedule lOS pipe, which has an inside diameter of 10.42 in (0.265 m). 

More than 40% oil can be achieved by heating the polymer at 25 K min to a final temperature of 700°C [30], The oil obtained is rich in aldehydes, ketones, carboxylic acids, alcohols and aromatic compounds 34% gas and 16% char were also produced. Pyrolysis at 500°C for 30 min leads to 73% gases, 19% solids and 9% liquids [31]. In this case a large amount of sublimed products are observed, which can cause problems by blocking pipes. Table 25.6 shows a comparison of different pyrolysis methods for PET.

Because the separator diameter is below 30 in (0.762 m), select standard pipe. From the chemical engineering handbook (6.66), the closest pipe size is 20 in (0.508 m), Schedule 10 pipe, which has an inside diameter of 19.50 in (1.625 ft, 0.495 m), an inside cross-sectional area of 2.074 ft2 (0.193 m2), and a wall thickness of 0.25 in (6.35 mm). From piping tables, the allowable pressure for carbon steel at 200 °F (93.3 °C) is 186 psig (12.8 barg), which is above the design pressure of 50 psig (3.45 barg). 

The computer program PROG36 calculates the Froude numbers for the liquid and vapor phases. In addition, PROG36 will determine whether the pipe is self venting or whether pulsation flow is encountered. Table 3-13 shows the results for the 2-, 4-, and 6-inch (Schedule 40) pipes. Table 3-14 gives a typical input data and computer output for the 2-inch (Schedule 40) pipe. 

Carbon and Carbon-Manganese Steel Pipe. Tables 23 through 26 list United States and European specifications for seamless and welded carbon and carbon-manganese steel pipe. Each table is intended to contain material that is equivalent in tensile strength and similar in over-all characteristics. 

Finally, it is often desirable to use a buffer that has no biological activity at all, so it can never interfere with the system being studied. TRIS is a very desirable buffer, because it rarely interferes with a reaction. Special buffers, such as HEPES and PIPES (Table 2.8), have been developed for growing cells in tissue culture. 

The OSHA HCS (29 CFR 1910.1200) requires employers to provide employees information and training on hazardous chemicals used in their work areas. Employers must conduct training at the time of their initial assignment and upon the introduction of a new hazardous substance. Training must address the methods and observations used to detect the presence or release of the chemical. It must also address physical and health hazards, protective measures, labeling, and an explanation of the SDS. Employers must inform employees of the hazards of nonroutine tasks and the hazards associated with chemicals in unlabeled pipes (Table 7.11). 

The section below the stack (and the fans) was used to host the electronic control boards, the DC-DC converters, and the H2 supply structure. Small fans were used to keep the control boards from overheating, and the hotter air was sent out of the system from the openings on the enclosure, as shown in Figure 5.7. The H2 supply structure included a pressure sensor, an inlet solenoid valve, an outlet solenoid valve, and metal piping. Table 5.3 shows the key parameters of the system. 

In the model the existing areas can be used (AHE,ex) by enlarging them with additional areas (AHE,add)- The additional annual depreciation of enlarged and new areas (AHE,new) of heat exchangers and pipings (Table 1), is multiplied by the payback multiplier (r = 0,2448) to obtain the maximum annual profit of heat and power integration ... 

As an introduction to the studies described in [19], it is pointed out that the experiments reported in [13, 14] do not allow an unambiguous conclusion of the influence of neutral salts on the formation of msty water. Experiments were therefore carried out in water which forms a good surface layer (Table 6) and has very low contents of substances such as organic carbon and phosphate, at a constant flow rate of 0.5 m/s in ND 20 steel pipes. Table 7 provides information on the neutral salt concentrations chosen. The results shown in Table 8 reveal the following trends in respect of the uptake of iron and the formation of msty water ... 

Steel pipes are rubber lined to a typical thickness of 6 mm (or 0.25") for small sizes of pipes [< 150 mm (6"), 9.5 mm ( ")], and 13 mm (J") for pipe sizes up to 24". Larger pipes may be custom lined. Lining is done in an autoclave and the rubber is cured under steam. Rubber lining is limited to pumping coarse material up to a size of 6 mm (= J"). Rubber does not contribute to the pressure rating of steel pipes. Table 2-3 presents the dimensions and relative roughness of rubber-lined steel pipes.

Any engineering or fluid-flow handbook contains tables of equivalent lengths of straight pipe for piping designs. These are based on the type of bend, its radius of curvature, and, often, the conditions of the inner surfaces of the pipe. Table 5-1 shows a suggested set of factors for bend and curve designs (Perry, 1950). More recently, a tremendous amount of work has been carried out by Ito (1959) to determine pressure losses in pipe bends. A typical pressure-loss curve as seen by Ito when...
