Baffle tangential feed

Tangential feeds, often with helical baffles, are commonly used with high-velocity feeds in which the vapor phase is continuous and the liquid is present in the form of a spray (143). These arrangements are discussed in detail in Sec. 2.2 (arrangement j). 

The common types of flashing feed and vapor distributors are the baffle type (Fig. 3.9a), the vapor-liquid separator type (Fig. 3.96), the gallery type (Fig. 3.9c), and the tangential entrance tjrpe (Fig. 2.2j). Some of the vapor distributors discussed in Sec. 3.12 are also sometimes used for flashing feeds, especially when liquid distribution to the section below is not critical (e.g., when it contains trays).
