I have an oil-flooded rotary screw compressor. This specific machine is female driven - motor shaft is connected to the female. This is one of the Leroi HG series.
Female has 6 lobes. Male has 4 lobes.
Assume gear ratio between female:male is 1. Assume female has 1000 RPM. This means female...
Is there any standards or charts that can help decide good operating temperature of a heater treater? A bit of studies I've done tells me that recommended heater T depends on the following:
1) API gravity of oil
2) viscosity of oil
3) operating pressure of heater
4) Field experience of your...
I've been reading through ISO 15156-2. There's two options for choosing corrosion-resistant materials in ISO:
1) Selecting from Annex A.2's Table A.2, which includes A106
2) More detailed selection guide based on the pH vs. H2S partial pressure plot
Since I'm interested in A106 already, it...
I'm planning to install 4x 500 BBLD oil storage tanks with API12F standards. It will be 12'(diamter) x 25' (height) storage tanks. My colleague tells me that there's a rule of thumb of maintaining 75' from the fire tube of a heater treater to storage tanks.
Three questions
1) Where's the 75'...
I'm trying to design a small (1.2 MMSCFD) glycol dehydration unit for an upstream facility. My client wants me to run the worst case scenario, which is 130F gas inlet with 2% water. I ran extensive simulations, and concluded that I must have a stripping gas going into the reboiler to achieve 7...
Hi, I'm seeing two kinds of P&IDs for primary separators from wellhead:
1) PSV venting to air
----> Safer, because it's always guaranteed to work (almost always). But its "dirtier"
2) PSV relieving to flare line
----> Cleaner, but if something goes wrong with flare line, HP shutdown will have...
Hi, I have a simple upstream wellsite facility design, shown in the below image.
Liquid comes from an HP separator (not shown) into the heater operating at 50 psig, 120F. The pressure on the heater is maintained by the back pressure valve set at 50 psig. The separated oil from the heater goes...
I never understood the purposes of using VRTs. The VRTs operate around 3~5 psig and gravity-feeds the separated liquid into the tank using VRT's own height. The VRTs are usually hooked up to a VRU, so if you can separate as much gas as possible from the VRT before atmospheric tanks, you can...
Hi, I'm tasked with sizing a separator + heater treater for a new well. The plan is to come up with some flow predictions, and give those info to manufacturers to recommend us vessel designs. But I'm not sure how to tackle the volume prediction...
Here's the given information
1) Wellhead ->...
I need to model the existing oil and gas upstream facility in P&ID. For now I'm focusing on the vertical 2-phase separator's liquid control system.
The separator has two liquid dump sides, one is usually closed and the other is usually open, but I still need to model both of them in P&ID. Both...
Hi, I'm curious if there's any free example P&IDs of any real facilities to learn from (I'm not looking for a class or a book). I have one pretty thorough company internal P&ID from one of our clients that I can learn from, but that's it. I am tasked with designing a P&ID for an existing oil and...
Hi, I have a pressurized 80% ammonia/20% water stream @300 psig/180F. Fluid is pressurized with a liquid pump (it's condensed before entering the pump) that we can fully control, so we expect to be able to maintain a stable pressure on the fluid (we don't expect any pressure swings). Also the...
