What does Industry consider an acceptable pressure drop across gas coolers (process gas aftercoolers) in Interstate Gas Transmission (pipeline) service in compressor station facilities? Is there a X to Y range of Psig values or a not to exceed X% of discharge-pressure. Looking for an go-by or...
Why is the compressor experiencing high temperatures in the range of 180F (RTD at discharge 10' comp. flange) when we simply gas-load the centrifugal compressor after a purge.
The impellers are not turning, we are just filling in the compressor with a loading valve before opening discharge for...
Does any one one a rule of thumb or method to derate the power on Roll Royce Gas Fired Power Turbines?
I have a RR 501KC7 that Id like to Derate under 128 ft of elevation and 90F. The manufactured rated Horsepower is 7200.
Any feedback will help.
Thank You .
Gentlemen,
What would be the derate of a 12" 900 Series Ansi Flange if I was to increase the bolt hole diameter. Is there a table or a contact that may supply this kind of information.
Additional:
Pipeline application
Purpose: allow additional aligining clearance
Any information will really...
For main line gas transmission and/or gathering, what would be the ongoing cost of gas compression for highspeed-separable green field compression. Including scrubbers, gas coolers, controls,valves, station yard and the nine yards?? I have heard #s between the $1800 to $2600 doller per...
Understanding that OEM would provide quantitative information. What im seeking here is a general comparative cost experience you may had, that answers
which driver option has been typically more economical for you? I am comparing two electric driver Toshiba,GE or Siemen vs the recip option Cat-...
When determining the overall compression required for natural Gas across a compressor or compressor station. What Delta P drop should I used for the suction and discharge of the compressor station assuming. Is there a rule of thumb of 5psig or something of the like for each side ( suction and...
Regardless of location what is a good suction temperature to size gas transmission Horsepower.
If the answer depends on compressor type. I am sizing for low-speed integrals and/or high speed separable cat-ariel compression.
What do you normally use 60, 70 80F??
Any help will help. Thanks.
Thanks In advance for any recommendations provided.
Can anyone recommend a user friendly and effective software to use to determine torque or tensioning requirements for flanges considering the gasket-flange material and geometry?
Any information would be of great help. Thank You!
