Dear Fellow Eng-tips technical experts,
I am trying to figure out what chemical reaction occers that frees up Hydrogen molecules in the following process
I have a wedge meter transmitter that we are experience hydrogen premeation from our process of CO2 fluid which contains H2S and produced...
All,
I am trying to predict the H2S content of produced water and oil at atmospheric conditions (tanks) by knowing H2S content of gas phase from my separator operating at 100 psig and 80F. This would help determine whether I need to specify NACE compliant materials.
Oil API gravity 40
SG...
I have a PSV valve report that gives me the calculated capacity of the PSV in scfm of air.
I need to know what the relief capacity is for another gas composition
help is greatly appreciated.
We currently have production wells with ESP (Electrical Submersible Pumps).
What are the typical safety devices to protect the flowline from rupturing form overpressure?
Our flowlines are polyethylene SDR 7 which are rated at 133 psi for Crude service.
The flowlines are tied into 3 phase...
I need to calculate volume stock tank vapors (scfd) to size Vapor Recovery Unit. The total volume needs to account for flash losses, working and breathing losses.
The facility currently has a 3-phase production separator which operates at normal operation pressure 50 psi ( min 35 psi, max 70...
Looking to install 3 inch stainless steel pipe. The service is produced water. My pressure is 2100 psig.
If i were using carbon steel i would buy 3 inch schedule 40 , Grade B (35000 yield strength) which for B31.4 is good for 2390 psig.
For stainless steel pipe does B31.4 apply? what yield...
Thank you BigInch.
Allthough if i have a 100 HP motor on the skid, but my curve shows the operating point only using 75 HP, should i run the numbers with 75 HP?
What am i consuming when i run at design point, the full skid 100HP or just what the rated 75 HP?
Hello All,
I want to evaluate 2 pumps for the following application.
S.G fluid: 1.05
Flow: 350 gpm
P: 600 ft head
I found 2 pump curves that work for my application.
-Curve 1: shows the design point requiring 75 HP with a pump efficiency of 80%. Pump would require 100HP motor to cover the...
My understanding is that API gravity of oil is a density measure at 60 F.
Would my API gravity of my Oil change at 1000 psi if i take it to a separator at 100 psi. I am assuming i will flash some of the light hydrocarbons (C1,C2) so my crude oil composition now changes.
Would the API gravity...
What does it mean when i am told a well produces 1000 barrels of total fluid with a GOR of 500 scf/bbl and 50% oil cut? with a wellhead pressure of 2000 psi at primary production?
How much oil, produces water and gas will i be producing?
does this mean 500 bbls of oil, and 500 bbls of water...
I need help in sizing a Vapor Recovery Unit. Basically i need to calculate total release volume to size the compressor and scrubber.
How can i estimate the total losses (flashing/working and breathing losses)? do i need to calculate all 3 to size a VRU for that capacity?
We have a...
More Information:
purpuse of the line to transfer fresh water SG 1. Freezing point 32F. Temperature of the water i would say 60 F, and constant flow. Allthough at upsets you can have no flow, where freezing is of concern. Its in new mexico where temperatures in winter go to 10 F.
The field is...
We currently have a 4000 ft of 10 inch SDR 11 polyethylene pipe which we are planning on laying below ground for fresh water transfer (lowest temp ever recorded 5 F, normal low temp is 20 F). The reason for burying the pipe is that we are concerned with freezing.
The problem we have is that the...
