Hi everyone,
Quick question, I work in gas compression services, mainly gas lift with pretty high discharge pressures (up to 3500 psig, three-stage reciprocating compressors), I came across with a analysis of a gas composition we sent for survey a few years ago and noticed it reaches...
Hi,
Can gas flow equations formulas like Weymouth, Pandhandle, AGA, General flow, be used to calculate the flow capacity of a vertical flare just by having P1 and assuming P2 being atmospheric pressure? I mean, it looks to me I can, since at the end it is gas flow through a pipe, but am I...
Hi,
I'm trying to calculate decent approaches to saturation pressure of hydrocarbon mixtures (methane to hexane). In an attempt to avoid going through EOS I came across with Antoine equation, which seems to deliver pretty accurate results with pure gases. I wanted to give it a try using...
Hi,
I´m working on a spread sheet to calculate required gas pipe diameter for given P1, P2 and flow (I´m ussing Weymouth, for some reason is the one has given more accurate results according to my fiel of job which is gas compression).
I´m putting also the recommendation for pipe schedule, and...
Hi,
In gas compression (with reciprocant compressors & combustion engines) sometimes we have no option but taking fuel gas from the discharge line. Given the most common escenario we usually encounter there is a gas feed at 70 kg/cm2, whereas our fuel stream pressure needs to be around 7...
For an oil well which produced gas be used as gas lift for itself, is it possible to reach, for example 1 MMSCFD if the well only produces 1.0 MMSCFD? assuming the gas is being recycled in a compressor of 2.0 MMSCFD capacity
For example, if we separate the well´s production (x number of BPD and...
We just revamped two identical reciprocating compressors, from 3 stages high pressure to a low pressure sigle stage, in order meet the following:
Required Operating conditions:
Suction: 25-40 psig
Discharge: 120 psig
Flow (calculated with compressor brand software [CiP]): 2.4 (25 psig suction)...
If I make the capacity calculation of an existing vertical gas scrubber (20" x 78")already installed in a compression skid I got as a result of gas handling capacity 2.0 MMSCFD (25 psig, 0.8 SG, 90°F).
The compressor (reciprocating, one stage) is going to actually handle now 4.0 MMSCFD, same...
Hi everyone,
In reciprocating compressors, what does it happen when the calculated flowrate is actually higher that the source is able to provide? Let´s say the performance states the compressors would compress, under the given conditions, a flow of 10 MMscfd, but the source is just able to...
Hi,
Let's say there is a gas lift compressor handling 2 mmscfd and it is to inject the gas to two different wells, with different pressures. One well is 3500 psig, and the other one is 2000 psig. I know the well with the lowest pressure will take the most of the flow but, how can I calculate...
Let´s say the well is producing (after a 2-phase separation process) 0.5 mmscfd of gas, we compress that and reinject it to the well. What would it be the gas flow now produced for the well? assuming there was no oil production increase (since the optimal parameters have to be found out still)...
Hi Everyone,
This is my first post in the forum, I´m Industrial Engineer, from Mexico. I work as a Project Engineer for a natural gas compression company. I´m now more often involved in compression infraestructures, I use to select the pipe diameters, valves, fittings and instrumentation...
