Vertical v/s Horizontal
Vertical: Minimization of layout area, greater selectivity in level control, high volume fraction of gas, small volume vessel
Horizontal: Low volume fraction of gas, long residence time for liquid, rapid variation in flowrate
Steps: 1. Calculate vessel diameter to satisfy separation and L/D, 2. Calculate T/T for surge/hold up
Target particle separation: Particle diameter is known. Typically know for typical services
Vertical vessel:
Determine vessel cross sectional area such that-
Allowable vertical velocity of vapor phase = Settling velocity of liquid particle * Margin
Margin: 0 to 1
Horizontal Vessel
