Subscription – always available and updated A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition. If the inlet liquid load is low, 1 above may not be important if the mist extractor can handle the liquid. There are two methods for sizing gas-liquid separators: This dependency of K S on pressure and droplet size is presented in Figure 2 .
August 7, at 8: This is particularly important for separators handling higher liquid loads.
Gas-Liquid Separators Sizing Parameter | Campbell Tip of the Month
Do you have a question? Entries Rdition Recieve follow up comments updates: PetroSkills offers consulting expertise on this subject and many others. Its value depends on several factors including:. Complete Archives Free Subscription. Mesh pads are the most common type of mist extractors used in vertical separator applications.
Along with inlet devices.
In the case of aoi cyclones, the vendor should be consulted in regards to performance for the current operations of interest. The benefits of a subscription: He is the author of most Tips of the Month and develops technical software for PetroSkills. You might want to look at the applications on my website.

Monitoring Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work. Separators covered by this specification may be vertical, spherical, editioj single or double barrel horizontal. September 11, at 7: In the following sections, we will discuss three sources.
Recieve new post updates: The primary separation mechanism is liquid impingement onto the wires, followed by coalescence into droplets large enough to disengage from the mesh pad. Want to read more articles like this? I think there should not be the square root on the right hand side of equation 5. These values are presented in Table 1. The Souders-Brown method is limited in that it is based on the average droplet size, but cannot quantify the amount of liquid sdition exiting the gas gravity section.
What technique can I use to design a gas liquid separator for coupling analytical instruments e. September 3, at 2: If the horizontal gas velocity profile is expected to be fairly uniform would need more details to determine this then 2 might not be a concern either.
Moshfeghian has presented invited papers in international conferences. Similarly, the terminal velocity for the other flow regimes like Intermediate and Newton can be derived based on their corresponding expressions for the drag coefficients .
September 18, at 8: Equation 6 is called Souder-Brown equation and K S is referred to as the design parameter. KS as a function of pressure and liquid droplet size for vertical separators with no mist extractor devices . Knowing the actual gas flow rate through the vessel, one can use K S parameter to determine the maximum allowable gas velocity through the vessel and determine the required separator diameter.
Sizing of the horizontal separators are more complicated. Please contact me to discuss a possible consulting project with your company regarding the design of gas-liquid separators. View all posts by: Posted on September 1, at The drag force acts to entrain the liquid droplet while the gravity force acts to pull it down.

edltion The maximum allowable superficial velocity or other design criteria should be considered for other type mist extractor. One can also use the appropriate value of K S to size the mist extractor in the vessel. Droplet settling theory method, 2.

April 22, at 9: In the December tip of the month TOTM , we discussed troubleshooting of gas-liquid separators for removal of liquids from the gas stream leaving the separator.
This is a great discussion. The drag force, F Dediiton exerted by flow of gas and gravity force, F Gis exerted by the weight of droplet. Once the maximum, V Gmaxgas velocity through the vessel is determined by Equation 6, one can calculate the required minimum cross sectional area of vessel for gas flow by the following equation. For the higher liquid load applications, i.
