Presented at IIAR 2001 Ammonia Refrigeration Convention

Virtually all of the liquid-vapor refrigerant separators used in the ammonia refrigeration market today rely on gravity forces to knock out or separate liquid from vapor (so called gravity separators). For additional background on vessels, refer to ASHRAE (1998).

The term g/l separator generally applies to most refrigeration accumultors which do not use demister pads or impingment vanes. A typical accumulator is depending on velocity reduction, change of direction, vertical separation distance and gravity for proper separation of the liquid and vapor.

ammonia and vapour so that only liquid ammonia enters the evaporator and vapours are returned to the compressor. This vessel is also, therefore, known as a liquid separator or gravity separator. Conventional designs use either horizontal or vertical accumulators, depending on various factors. The design, selection and . Separator Analysis

Fundamental principles for sizing and design of gravity

Fundamental principles for sizing and design of gravity separators for industrial refrigeration. In order to achieve complete separation of the waterevapor mixture, a separator was designed, produced, and used in the experiments by taking into account the forces acting on a droplet, the maximum allowable vapor velocity,

Introduction to Ammonia Refrigeration Systems

Refrigeration Systems ASHRAE is a Registered Provider with The American Institute of Architects Continuing Education Systems. Credit earned on completion of this program will be reported to CES Records for AIA members. Certificates of Completion for non-AIA members are available on request.

Selecting, Installing Oil Separators

Oil separators are essential on low or ultra-low temperature refrigeration systems and on large air conditioning systems up to 150 tons. Most compressor manufacturers require oil separators on all two-stage compressors. Oil separators can also act as discharge mufflers to quiet compressor pulsation and vibration noises.

Energy Efficient Gas Cooling for Two -Stage Ammonia

,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.

2. Function of a gravity liquid separator

In industrial refrigeration, only single-component liquid from vapor separation is of interest. Gravity liquid separators for industrial refrigeration applications have two main functions: 1. Provide sufficient separation space to separate virtually all liquid from its carrier vapor to protect compressors from liquid carry over, which can:

Separator Sizing

The liquid then flows down the pocket to a trough and is routed to a drain pipe and into the liquid portion of the separator. The drains are either routed to below the low level shut down point, or have pee traps. The drains must have some form of liquid seal, or entrainment laden gas will flow up the drain.


Separators") to familiarise themselves with the general design philosophy and the characteristics of the various separators. After selection of the desired separator the design rules can be obtained from Section 3. Further guidance for debottlenecking of existing separators is given in Appendix XI.

Coalescing Oil Separators

turn are routed by gravity through a drain layer. Coalescing separators maintain the same level of effectiveness down to almost 20% of the separators rated load. This is increasingly important as more stores employ refrigeration load shifting/matching to reduce energy consumption. Rival centrifugal designs do not share this ability,

Vacuum Gravity Separator

The Vacuum Gravity Separator has an international reputation for being the most effective gravities in the industry. The precision control of airflow, speed of vibration and differential action of the deck ensures excellent gradation and separation.

Gravity separator

The gravity separator is utilised when the limits of air-aspiration systems and screening are reached. The gravity separator cannot replace these earlier sorting steps, but is an additional piece of equipment for separating more accurately according to specific weight.

Other types of separator enhancements besides demister pads are available, but in the refrigeration industry gravity separators are used almost exclusively. Vertical vessels have the advantage on a fixed cross-sectional area, so the separation velocity does not change as the liquid level increases.

Ammonia Oil Separator

1. Product Description. Our ammonia oil separator is used for separation of ammonia and oil. Based on the principle that oil and ammonia have different specific gravity, the separator makes the mixed gas go through a vessel with large diameter, during which, oil sinks and is separated from the gas due to the change of flow rate and direction.

Oil management in a refrigeration system

The internal fitting of TURBOIL separators enables to differentiate the separation and oil reserve stages so as to limit the risks to carry over the oil stored. 3) Conclusion. It is possible to optimize the oil management in a refrigeration system by respecting the 3 following rules:

Flotation is a gravity separation process that exploits the differences in the surface properties of particles. The separation process is based on the use of very fine gas bubbles that attach themselves to the solid particles in suspension to make them buoyant and drive them toward the free surface of the liquid.

Refrigeration Service Today: Oil Separators & Service Valves

Oil separators are used on refrigeration systems where its difficult for the oil to return from the evaporator. These typically are field built-up systems, such as in supermarkets, and ultra-low temperature systems. Oil separators are installed in the compressor/ compressors discharge line. They

Coalescing Oil Separators

refrigeration system, equipped with a coalescing type oil separator, consumed less energy per ton of cooling than a system with other types of separators, or no separator at all. By conservative, I refer to the fact that tests were done without cycling/unloading procedures. Instead, higher circulation velocities were employed to insure

Alfa Laval

The Alfa Laval P separator is designed for well-defined oils with fewer process issues. The separator bowl has manually set gravity discs to deliver high performance but does not automatically compensate for process fluctuations. The separator bowl can be configured as a purifier or as a clarifier. A purifier removes solids and water from oil.

Vaporliquid separator

A vaporliquid separator is a device used in several industrial applications to separate a vaporliquid mixture. A vaporliquid separator may also be referred to as a flash drum, breakpot, knock-out drum or knock-out pot, compressor suction drum or compressor inlet drum. When used to remove suspended water droplets from streams of air, it is often called a demister.
