One of my pet peeves is people who use the term slug catcher when they are really refering to separators.
First thing you have to do is to figure out how big the slug is. If it is the result of pigging then it will be of considerable size.
If you want to see what the pipe or finger type slug...
the answer is yes. however, you may not like the cost.
in general, the higher the power gas pressure then the lower the cost of the actuator. that is why stanier suggested a hydraulic type actuator.
there are companies who make a skid mounted, mini central hydraulic system to go with the...
I am checking the calculations for a pipeline slug catcher and found that the exit riser piping is way too small which will allow the exit gas stream to entrain liquid droplets and carry them over to a filter-separator.
Is there a method to estimate the quantity of liquids that would be carried...
I am interested in a publication "compressible flow manual" by B.M. Coulter. Publisher is Fluid Research Publishing Co. of Melbourne, FL. Date was 1984.
Cannot seem to find the publication or the publisher on the internet.
the above was listed as a reference in API 521.
So, anyone have any...
I just want to grind numbers in Fortran code. All calculations would be contained from within the program and would not import subroutines in other languages.
My old programs used a screen input which I would like to continue.
I once took two classes in C and do not like it for many reasons...
Last Fortran program I had was Microsoft Power Station Fortran V1.0 which Microsoft dumped. When the program began to give me fits on the network version of Windows 98 I threw in the towel.
I would like to once again use some of the programs that I previously wrote so I need to buy a new...
The longitudal stresses caused by bending are limited by ASME B31.8, etc.
The design criteria may be more related to how much pipe deflection you are willing to accept as opposed to the possibility of buckling.
MSS has a spec that suggest pipe support spacing that most people use for smaller...
I agree with jdonville in that compacted sand should be installed until you have 12" of cover and then it does not matter if he uses CA-7.
BTW, my field experience is that it is very difficult to get a contractor to fully compact the soil around pipe to meet the drawing specs unless you...
What a terrible installation!!!!!!!!!!!!!
It sounds like someone guessed at the foundation size before the generator was purchased. Often times people use one manufacturer to base the preliminary foundation size on for construction bid purposes and end up with another manufacturer having...
Richardson is another good source.
To me there are 3 components to a cost estimate: labor, permanent project materials and equipment.
For the later, the equipment used on a project can vary from contractor to contractor. And the cost of equipment is somewhat dependent upon if it is rented or...
The learning experience of developing your own spreadsheet is priceless.
I will give you a start. Use the Lee, et al method for calculating viscosity. The Lee method is normally used when you only know the gas SG.
All:
Thanks for the help. BTW, I live in OK where it normally gets cold enought in the winter to kill all the bugs. However this winter we have had only a few weeks of cold weather so there may be a price to pay next summer.
Welding of high yield pipe generally requires pre-heat which is not normally used for welding Grade B.
So are you pre-heating the welds? Usually it is to 250 F.
Common practice is to butt weld pipe 2" and larger and either socket weld or thread pipe less than 2".
Fittings less than 2" are usually forged - that is A105. Larger size fittings are castings - that is A234. I am sure the choice of material is an economic issue and where the break point is...
corrosionman:
1. Sandblasting outside of pipe only.
2. New pipe. However, pipe is delivered via ocean freight so I am unsure of the surface condition when it actually gets on site.
3. Pipe diameters range from 2" to 20" with some 30". Actually there are several facilities.
4. Site...
Guess I did not want to name names.
The old CB facility in Mt. Vernon now packages gas turbine driven units using Rolls Royce units. No recips.
They are now called Rolls Royce.
The recip part of their business was sold and moved to Houston where they sell the high speed type units.
To my knowledge, the old integral, slow speed type compressors are no longer in production in the USA. Of course you could buy a used machine.
I agree with David that the Ariel compressor is the vendor of choice for recips.
BTW, the Ariel compressor is manufactured in the same small Ohio town...
More correctly, for any valve through which a pig must pass should be full conduit. That is, specify the bore of the ball to be the same as the adjoining pipe ID as a minimum.
I agree that all 3 valves should be full port ball valves.
I did a compressor station pressure loss study about 10...
