- Total Removed by Count
% Of Total Particles Of A Certain Range or Minimum Size.
i.e. 99% of all particles 10 microns and larger.
i.e. 100% of all liquid particles 8 microns and larger, and 100% of all solid particles 8 microns and larger.

Pocketed Vane Design
We will now cover the various configurations and models that we have to offer. The actual model numbers are not important here unless this training is for a representative. The first separator that we will talk about is the vane type separator. The main thing to point out on this slide is the efficiency of a vane separator and the fact that we use a pocketed vane design.

This slide shows the evolution of vanes. What you are looking at in the four boxes on the right side of the slide is a top down view of a vane box. Ina all cases the gas flow is from the left to right. Generation one shows what we call today a chevron. The main premise in all of these devices is that the gas can easily make it through the wavy path between the vane elements and the heavier liquid particles are going to impinge on the face of the vane. Once the particle impinges on the face of the vane gravity can take over and the liquid drains into the sump. With the generation one vane profile it is easy to see that a particle that impinge and or near the crest of the vane would have a good chance of being sheared off and reentrained into the gas stream. This is not good. This problem lead to adding hooks to the basic chevron design. This is shown as generation 2 and 3. These designs worked and are still supplied by some manufactures today. The problem with hook style vanes is that with the hooks hanging out into the gas stream both the differential pressure and the size of the vessel in which the vane box is fitted begins to grow. This short coming lead to the development of the pocketed style vane. This is the standard vane element for Anderson. The idea here is that a liquid particle that impinges on the face of the vane will travel up the face of the vane until it reaches a pocket. Once the liquid falls into the pocket it is out of the gas flow and can be drained out very easily. This makes the pocketed style vane the most efficient vane type separator offering the highest removal efficiencies with the smallest vane area. This means smaller vessels and lower pressure drops.

10. Vane Performance Standard Efficiency is 100% of 8 > Liquids only
Some Solids Entrained with Liquid OK Consult Factory
Addition of a Coalescing Mesh Pad Increases Efficiencies to 100% of 3 >
TURNDOWN IS EXCELLENT: Down to 10% of Design Flow in Every Case
The other very important thing to point out about vane type separators is that they have a 10 to 1 turndown ratio. This means that the vane type separator will operate at the stated efficiencies from 10% to 110% of the design flow. THIS IS NOT THE CASE WITH ALL SEPARATORS. It is very important to take this into consideration when specifying separation equipment.

This slide shows a typical cross section of an inline vane separator. It is called and inline vane separator because the inlet and outlet are inline with each other. The vane box is welded into the vessel between the the inlet and outlet therefore all of the gas must travel through the vane. All of the points on the slide are applicable but most have been covered at this point. Take time here to point out that this unit is not recommend for high liquid loads or slugging applications. A typical vane is about 6 inches in depth. This would be the width of the box measured from left to right as you are looking at the slide. If a large amount of liquid impinges directly onto the face of the vane there is a high probability of carry over.
In many gas processing applications the potential for intermittent high liquid loading conditions is common. For these types of applications we would specify the vertical gas type separator shown on the next slide.

13. AVGS Type Vertical Gas Separator
Same Principle as The AVS Type Separator
Primarily Used Where Liquid / Gas Ratios Exceed 5% by Weight
Also Used For Slugs Or Where Liquid Hold Up Is Desired To De-gas Liquids
This is the vertical gas separator. The main difference is that we have now moved the inlet nozzle down below the vane box. By doing this the large liquid loads can be removed in the first stage and then the gas must travel vertically upward and through the vane box.

Another use for the vane type separator is to remove condensate from steam as it exits the boiler drum. As the customer base for this application is limited you do not need to spend a lot of tie on this slide but it is good to let reps and customers know that we can and do cover a wide range of separation applications.

16. Required Information The Big Picture Gas Flow Rate Removal of What?

Minimum / Maximum Operating Temp.
In order for Anderson Separator to size the separation equipment we require several pieces of information.
The Big Picture - Anderson is not in the engineering consulting business but it is very helpful if we know what process the separator is being placed into we can often make recommendation to help ensure that the separator will meet the requirements of the application.
Gas - Steam, Natural Gas, Air, etc. It is also important that we know or can calculate the specific gravity of the gas. This is used in our sizing program.
Flow Rates of gas
Min and Max Operating and Design Temperature and Pressure - The design numbers are used to design the pressure vessel. The operating conditions are needed to size the vessels. Anderson will size the vessel for the worst case scenario. That is minimum operating pressure, maximum flow rate, and maximum temperature. This is the most conservative design approach. If we are explicitly total that these conditions will not all happen at the same time we will be happy to size for actual worst case but this information has to come from the customer.
Required removal efficiency - we have just talked about many different many different separator configurations and there removal efficiency. This is the starting point for specifying the proper separator.
Continued on next note page

17. Required Information Pressure Drop Arrangement Connections Materials
ASME Code Information
Removal of What - Solids, liquids, or both.
Slugging or High Solids Loading - Special provisions need to be taken in the vessel design for these applications
Pressure Drop - It is critical that an allowable pressure drop be specified. Pressure drop is one of the design criteria for all separating equipment and can make a significant difference in size, cost, and performance of the separator.
Arrangements and Connections - Most of these details will be handled during the approval drawing process but it should be considered early on as it can affect the cost of the unit.
Materials of Construction - The majority of separators are made out of carbon steel and stainless steel. Other materials can be quoted.
ASME Code Information - We do not expect the customer to interpret the code to us but if they have there own pressure vessel standard or requirements over and above that of the ASME code we need to know that at the time we quote the job.

Dump Valves
Many separator RFQs also include instrumentation. The discussion of each piece of instrumentation is a completely separate presentation all to itself.
Typically most discussion revolves around how to get the liquid out of the vessel. One popular way to do this is to use a pneumatic liquid level controller to control the level. By taking gas off of the outlet side of the separator and regulating the gas pressure down and piping it to the level controller we ca then operate a diaphragm type dump valve to drain the liquid out of the vessel.
Relief valves are limited to thermal relief only.
Differential pressure indicators are required on filter and coalescers. Differential switches and transmitters can be supplied but will add cost to the device.

19. Conclusion
Separators are critical pieces of equipment for the smooth operation of most all processes.
Different applications require different approaches, different styles of separators, and sometimes units in combination.
IT IS IMPORTANT TO GET ALL THE INFORMATION CORRECT THE FIRST TIME-- SAVES TIME AND $$
