Spray cleaners comparisons

One of the biggest current questions is whether the recent boom in wipe products will continue in the future. Wipe products are very expensive per use compared to even the combination of a spray cleaner combined with a paper towel, never mind the comparison to a dilutable bottled cleaner and a wash cloth (which can be washed and reused). However, products with higher per use price but much improved convenience, such as trigger spray cleaners, have survived... 

The characteristics of different process layouts are listed in Table 9.6 [22]. The open-cycle layout, which represents the majority of spray dryer systems, is shown in Figure 9.29. The drying air is taken from the atmosphere and the exhaust air is discharged to the atmosphere. Three types of dry collectors and a wet air cleaner can be used in this layout. A relatively large amount of dry powder (in comparison with other layouts) is lost with the exhaust air. Some applications are shown in Figures 9.30 through 9.35 [33].
