(PDF) Gravity Separator Fundamentals and Design Nelly
Wu (1984) developed fundamental methods of separator design that used a simple force balance and correlations for drag force on a spherical droplet Wu recommends that the design vapor velocity for a vertical separating vessel should be 75% to 90% of the terminal velocity; however, a specific design droplet size never recommendedThe basic principle of operation of the gravity separator is that it takes ad vantage of the difference in size, shape and specific gravity of particles The actual separation takes place in THEORY AND OPERATION OF THE SPECIFIC GRAVITY The term "Gravity Separator" is a contraction of the proper name "Specific Gravity Separator," which means, a separator of par ticles differing in their specific gravities About 250 BC, Archimedes discovered the law of specific gravity which is: "ALL BODIES FLOATING IN ORGravity Separator Operating Instructions ManualThe design of the separator is based on the specific gravity difference between the oil and the wastewater because that difference is much smaller than the specific API oil–water separator WikipediaThe gravity separation table, or air table, is commonly used to separate particles by weight and density A separation table can be used for any dry material as it moves on a “fluidized” bed Gravity Separation – Oliver Manufacturing How it works
Gravity Separation Principle, Uses and Applications
The gravity separator separates particles of significant difference in specific gravity, but only for an arrow range size It could be down to 005 mm for new technologies, but if there are particles of 1 mm, which means a broad size distribution, then the gravity separation will be less efficientSw = specific gravity of wastewater at the design temperature of flow So = specific gravity of oil in wastewater at the design temperature of flow Note: Sw and So are specific gravities and are nearly the same numerically but differ dimensionally from u0003w and u0003o which they replace(PDF) APPENDIX 5 SEPARATOR DESIGN METHODOLOGIES Jul 06, 2015 Separator design basics Separators are typically sized by the droplet settling theory or retention time for the liquid phase For illustration purpose, a general procedure based on retention time appraoch is as follows 1Separator sizing PetroWikiIn actual practice, separation of oil droplets down to the 30 to 40 micron range is a realistic goal for any enhanced gravity oil/water separator If you do come across someone who says that their separator will "remove 99% of all oil droplets greater than 20 microns" ask Design and Sizing of an Oil/Water Separatordebottlenecking an existing separator, full knowledge and understanding of the basic principles involved are required Often overlooked are the capabilities of properly selected and designed internals for the enhancement of simple gravity separation This LiquidLiquid Coalescer Design LiquidLiquid Coalescer Design Manual

API oil–water separator Wikipedia
The API separator is a gravity separation device designed using Stokes' law principles that define the rise velocity of oil droplets based on their density, size and water propertiesThe design of the separator is based on the specific gravity difference between the oil and the wastewater because that difference is much smaller than the specific gravity difference between the suspended solids Specific Gravity Separator The gravity machine has in the past had a reputation of being a difficult machine to operate and to keep in adjustment In reality, it is a very simple machine to operate if the principle behind its operation is understood The two main parts of the gravity separation process are air and table motion IfTHEORY AND OPERATION OF THE SPECIFIC GRAVITY The design of separators can require design over a wide variety of temperatures (and therefore water viscosities) to account for summer and winter conditions, as well as possible process upsets, so several water viscosities may be considered during design The specific gravities are usually known or can be readily estimated TheHOW OILWATER SEPARATORS WORK AND HOW TO USE Apr 02, 2012 The API oil/water separator is a simple gravity separation device designed by using Stokes Law to define the rise velocity of oil droplets based on their density and size The design of the separator is based on the specific gravity difference between the oil and the wastewater because that difference is usually smaller than the specific API Oil/Water Separators: Simple But CostlySpecific Gravity Separator The gravity machine has in the past had a reputation of being a difficult machine to operate and to keep in adjustment In reality, it is a very simple machine to operate if the principle behind its operation is understood The two main parts of the gravity separation process are air and table motion IfTHEORY AND OPERATION OF THE SPECIFIC GRAVITY
