2.1 Bubbling oil separators. Ammonia vapours in bubbling oil separators come from the compressor into the inner pipe, which outlet is 125…150 mm below the fluid level in the apparatus. When the refrigerant vapour passes through the liquid refrigerant layer, not only oil drops are gathered but oil vapour becomes condensed as well.

Ammonia Gravity Separator Design Split P. Software for Design of Separators of gravity flooded ammonia installations would reveal an amazing range of accumulator sizes for identical capacities and a variety of methods for mounting them The design of an accumulator or gravity separator is a complex subject as the forces acting on liquid droplets are gravity pull on one side
Abstract Throughout the past decades, the industrial refrigeration industry has developed various "rule of thumb" methods for sizing gravity liquid separators for ammonia and other common refrigerants. However, to date a uniform systematic approach or an agreeable standard has not been established. For commonly used refrigerants such as ammonia, the large installed base of separators can ...

The model presented can serve as a basis to establish a fundamentals-based new design method for gravity separators. It is not the purpose of this paper to develop or recommend design guidelines; rather it is a literature search and analysis to put the existing design guidelines on the same basis for ammonia.

Wiencke (2011) analysed the fundamental principles of the design of gravity liquid separators and applied the single-droplet model to the sizing of gravity liquid separators.
ammonia gravity separator design,Virtually all of theliquid-vapor refrigerant separatorsused in theammonia refrigerationmarket today rely ongravityforces to "knock out" or separate liquid from vapor (so calledgravity separators). For additional background on vessels, refer to ASHRAE (1998).

Drainage Area – Gravity separators are typically used for areas less than 5 acres. It is recommended that the contributing area to any individual gravity separator be limited to 1 acre or less of impervious cover. The total wet storage of the gravity separator unit should be at least 400 cubic feet per contributing impervious acre.

(PDF) Gravity Separator Fundamentals and Design . A primary design goal is to size the separator such that the drag and buoyancy forces succumb to the gravity force causing the droplet to disengage, ie separate, from the vapor flow The force balance on a typical liquid droplet can be established by application of Newton's Law: ∑ F at f = m a at f n !

GRAVITY SEPARATOR DESIGN,The design criteria for gravity liquid separators dictate that for a given separating distance,· liquid carryover will be limited to the smallest size droplets when the vapor velocity is the lowest (Hiller 1971) (Wu 1984). This, of course, suggests the choice of large diameter vessels for phase separation.
