API Specification 12J Eigth Edition, October 2008 Specification for Oil and Gas Separators API Monogram® Required Yes No Handbook Revision 10. Recent wellsite disasters have led to an increased emphasis on properly sized mud/gas separators. Key details include a vessel diameter of SPECIAL NOTE: In 5-d above it states that API-421 does not generate data in regard to oil droplet size distribution, and this is correct. Allowable stress: affected by temperature, inside diameter, TL/TL, and material selection. It calculates the density and viscosity of water, rise rate of oil The design procedure for horizontal-separator sizing results in a range of configurations of vessel diameter and length that will perform adequate-liquid separation. Novel sizing data for conventional oil-water separators were generated from API design criteria. Note: Typical sizes at Petroleum Industry sites in New Zealand are smaller. This document provides information and calculations for sizing an API oil-water separator. Historically the Souders-Brown equation has been Considerations in separator sizes is important during design. Flow rate of water = 18 m3/hr Entrained Flow of fuel gas = 100 m3/hr Operating temperature of separator = 25 0 C Operating pressure of separator = 0. Based on API 12 J, K values which based on type and height of separator are used for reference especially for separator with mist eliminator (See API 12 J, Table C. 5 Considerpossible separator.

In Part 1 of this series, the author noted that historically, the sizing of three-phase separators, in particular for oil/water separation, has been based on the specification of residence time criteria, which is an imprecise method as residence time alone fails to capture many of the parameters/variables that clearly should have an impact on liquid/liquid phase separation Summary. 2 Types of Separator API tanks (see Figure 33. 167 This calculator is used to size horizontal gas-liquid separators such as knock-out drums. 1 - 2. CHOSEN SIZE: 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. 5 in refinery services. 01. An API separator is the name given to a horizontal, rectangular cross-section, atmospheric oil skimmer that follows the sizing equations and guidelines included in the API Manual on Disposal of Refinery Wastes. I will use an example to explain step-by-step sizing of two-phase vertical separator. 75", or 1. Typically, the difference between the specific gravity of the oil and water is much closer than the specific gravity of the suspended solids and water. Many references (Kirby and Mohr. Accessories and Options. The ratio of separator depth to separator width (d/B) typically ranges from 0. Keywords 00800-0400-4496, Rosemount™ 396P pH/ORP Sensor, Rosemount 5081 Explosion-proof Transmitter, rugged environments, refining, chemical processing, pH measurement, pH sensor, API Separators This calculator is used to size vertical gas-liquid separators such as knock-out drums. Schoepentoeter / Cyclones / Demisters / Sand Jetting headers, Plate Pack Coalescers). Typically, the difference between the specific gravity of oil to be separated and water is much closer than the specific gravity of the suspended solids and water. In Oily water treatment, tilted (placed in predetermined angles) plate packs are used in CPI/ TPI separators to improve the size and economy of the separator system. The gas-liquid separation section is determined by the maximum removal droplet size using the Sauders-Brown equation with an appropriate K factor. An obvious thought is to just use the production data obtained through the simulator and use it in the simple API 12J calculations, but the flow rates are not enough. Table 1 & 2 - Correction Factor 2 . It determines the maximum water and oil flow rates to the separator based on site characteristics. Separator vessels are commonly used in refinery, petrochemical plants, or gas processing plants to separate the vapor-liquid mixtures, and three phase mixtures, these vessel may be called knockout API-421The API-421 uses a variety of innovative technology (such as velocity-Head Diffusers, Reaction-Jets, Flight Rake System, Corrugated Plate Packs, Oil-Skimming Devices, etc. The document provides calculations to size an oil water separator based on input parameters such as flow rate, water temperature, oil droplet size, and amount of installed media. The use of API separators should be limited to protection from large oil spills and not for small amounts of oil on the pavement surfaces. Vertical two phase separator. Step-by-step sizing two-phase vertical separator. The novel design approach, innovative design approach and alternative design approach for conventional oil-water separators were invented; each based on different mathematical models. The equations for sizing an API separator and their derivations are discussed in Removing solids from water#Gravity A. C. Design criteria is based on A diagram of a typical API separator is shown in Figure 1 below adapted from API (American Petroleum Institute 1990). 1 The Separator Sizing package included in ProMax is capable of helping you size both horizontal and vertical separation vessels in a multitude of process conditions, including separators, scrubbers, knockouts, flash drums, and slug catchers. File Size: 2 files , 3 MB Product Code(s): WD, WD, WD. The equations are derived using the same principles. It calculates the maximum gas superficial velocity, density of liquid and gas, area and diameter of the vessel, and liquid volume and capacity based on inputs for gas flow rate, molecular weight, and densities.

The liquid capacity of most separators is sized to provide enough retention time to allow gas bubbles to form and API has established certain design criteria for determining the various critical dimensions and physical features of a separator. Gravity Separation The API separator separates via gravity and the density differential of liquids per Stokes Law, which defines the rise rate of an oil droplet based on its density and size. Oil droplet size to be removed (in microns) 30 microns typical AH = horizontal separator area, in M 2 0. 1-20 of 4,715 results 20 results per page 10 results per page 30 results per page 50 results per page This specifications covers one type and size of parachute removable connector link separator. Droplet settling theory method, 2. The calculator determines the vessel diameter and height required to achieve the specified separation. Any manufacturer producing equipment or materials represented as conforming with an API specification is responsible for complying with all the provisions of that specification. Particles smaller than 150 micron will normally exit an API separator and will need to be removed by downstream treatment processes, unless allowances are made in the sizing of the API separator to remove these smaller particles. ) mentions that this principal simplifies the overall The basic separator sizing is still being done on the basis of API 12J specifications and the different flow rates that may arise during the production lifetime are also not taken into account. API SEPARATORS PROVIDE EARLIER RECOVERY OF REUSABLE OIL Our API separators treat and remove up to 80 percent of oil from refinery process water and storm run-off. The document details sizing calculations for an oil-water separator. The oil-water separation section is held for a retention time that is Historically, liquid residence time guidelines (for example, API 12J 1989), have been used to size the liquid-holding part of the separator for degassing purposes. Figure 1 & 2 - Gas Capacity of Horizontal Filter Separators 3-4 API gravity hydrocarbon, usually referred to as distillate or condensate. 09 Refer to pages 19 – 20 of API Spec 12J Purchase API Spec 12J online at www. wt.
