The most common types of wet scrubbers are spray towers, venturi scrubbers, packed bed scrubbers and impingement scrubbers. Spray towers are the simplest, least expensive, however not very efficient, tar separation devices [23]. 

A review of Table 8 and Fig. 3-2 indicates that large-diameter particles can be removed with low-energy devices such as settling chambers, cyclones, and spray chambers. Submicron particles must be removed with high-energy units such as bag filters, electrostatic precipitators, and venturi scrubbers. Intermediate particles can be removed with impingement separators or low-energy wet collectors. Obviously, other equipment performance characteristics as noted in Table 8 will also have their influence on the final equipment...
