hello all,
ESP pumps are useful to enhance oil production in the oil wells. Is anyone familiar with ESP pumps with respect to the electric motor hazardous zone?
Does the motor have to be explosion proof or not?

what is the limitation for selecting the atmospheric floating roof storage tanks instead of fixed roof?
what is the limitation of atmospheric floating roof storage tanks with respect to flash point or vapour pressure or MW?

On manned offshore production platforms, the LQ is located in an unclassified area (or safe zone) far away from the facility, sometimes connected to the facility by a long bridge.
However, LQ is pressurized with HVAC systems to prevent gas from entering the LQ. My question is why positive...
I have some confusion regarding the choke valves on oil and gas wellhead.
A. Choked flow is a limiting condition where the mass flow will not increase with a further decrease in the downstream pressure environment for a fixed upstream pressure and temperature.
B. On the oil and gas wellhead and...
API rp 14c on attached Figure A.3 Satellite Well recomend 2 SSV,s or 2 SDV,s plus one SSV upstream of choke valve.
Have any body exprience about this arrangement. I have not ever seen 2 SSV in seri upstream of choke.
thanks for any respond...
polytropic efficiency formula used in compressors is equal to"
((?-1)/?)/((n-1)/n)) that ?=gamma
foe example when n=1.3 and ?=1.4
polytropic efficiency is:
(.4/1.4)/(.3/1.3)= .29 / .23= 1,24
polytropic efficiency for this compressors is equal 1.24.(greater than 1.00)
We know that the maximum...

my question is about comparison between relief system (psv and its flare system)and HIPPS system
with respect to RAM and SIL study.
Which following is true or false?
1. Maitainability of the psv systems is better than the HIPPS system.
2. Availability of the psv systems is...
Dear friends,
I would like to request assist to the following query:
I have attached "Figure B.1—Example Safety Analysis Flow Diagram of Platform Production Process" from API-RP-14C EIGHTH EDITION, FEBRUARY 2017".
As you can see the quality of this drawing is not good. I am looking for a better...

what is reason that Pressure Vessels subject to partially vacuum should be designed for full vacuum?
I have seen many pressure vessel data sheet that have for example 70 KPa absoloute with full vacuum desighn pressure.

Hi ,
it might be a pretty basic question, but any help will be great. I'm trying to select an air compressor with capacity of 580 Nm3/h. I'm having a bit of difficulty finding the right decision to doing it. In manufacture catalogue data are based on FAD (free air delivery) and is 588. Is there...
