Advantages of the vertical separator

Once a liquid droplet is allowed to settle through a continuous vapor phase, the settling velocity depends on the particle size, resistance to settling (defined as drag), and densities on vapor and liquid phases. The critical settling velocity is defined as

The sizing of a separator depends on the value of empirical constant Kjy. The value of is largely influenced by the presence of internals. Normally, internal manufacturers specify the particular value of Kp, based on their test results. It is always advisable to get the value of from the internal manufacturers before finalizing a separator design. In fhe absence of manufacturer data, the data presented in Table 3.1 are often used [1,3]. 

The value of K also depends upon fhe operating pressure, and tiie effect of the pressure on the allowable K factor can be defined as given in Reference 3. Table 3.2 gives the effect of pressure on allowable K factor. 

For horizontal separators, the separation efficiency depends on tiie total vapor travel length within the vessel. A longer vessel makes it easier to
