Cooling mechanical design

Single-stage or two-stage cooling is used to achieve the desired degree of cooling. These alternatives achieve the same thermal efficiency, but offer different approaches to low pressure drop operation and mechanical design. 

Sohds in divided form, such as powders, pellets, and lumps, are heated and/or cooled in chemical processing for a variety of objectives such as solidification or fusing (Sec. 11), drying and water removal (Sec. 20), solvent recoveiy (Secs. 13 and 20), sublimation (Sec. 17), chemical reactions (Sec. 20), and oxidation. For process and mechanical-design considerations, see the referenced sections. 

Targer sizes of water-cooled condenser require closer packing of the tubes to minimize the overall size, and the general form is shell-and-tube, having the water in the tubes (Figure 6.4). This construction is a very adaptable mechanical design and is found in all sizes from 100 mm to 1.5 m diameter and in lengths from 600 mm to 6 m, the... 

Prepare mechanical design sketches of the absorption tower suitable for submission to a draughtsman, paying particular attention to the tray layout and any associated cooling equipment. 

Heat of Nitration. The nitration reaction must be controlled by systematic cooling designed to withdraw the energy evolved. When all the energy set free by an exothermic reaction is forced to appear as heat, the quantity of it lost to the cooling mechanism equals the decrease in enthalpy ...
