Hello colleagues,
I have a centrifugal compressors map performance: relating Polytrophic Head vs. Inlet Flow and representing the speed curves and efficiency curves.
My question is:
How from this curve can I obtain the curve representing this both identical compressors working in parallel...
I am looking for calculating the overall polytropic efficiency for of two compressors in parallel.
I have the performance map from the supplier for both compressors with the polytropic head depending on the flow rate; the speed and the efficiency are also represented.
But for two different...
Dear colleagues,
My customer ask me replace a pressure transmitter voting system 2 out of 3 for a single transmitter SIL 2, I do not agree because the ESD system will be more sensitive to the pipe problems, Do you have more reasons?, or do you agree with my customer?…

Dear Sirs,
Can anybody supply a web link, or send me a manual where I can find the following issues related to oil products storage tanks:
Design philosophy
Operating philosophy
Safety philosophy
Environmental philosophy
Thanks,
Dear Sirs,
I wonder if the JT effect that occurs in the orifice plate to depressurize natural gas from a pressure of 70 bar a is enough to calculate the gas lowest temperature at downstream orifice flow.
My concern come from the fact that the JT effect does not consider the kinematics energy...
Dear Sirs,
We are currently working on the dynamic depressurization utility of Hysys, in detail we are simulating a natural gas pipe depressurization using the General (Choked Flow) valve equation, and specifying the Av coefficient, which is the orifice area (leak area) for simulating the...
Hi guys,
Anybody know what is the process fundamental of the bacteriological water treatment? Please, could you sent any links about process description and process flow diagrams,
regards
Hello Guys,
I’m working on a new project where there are 6 equal turbo compressors in parallel to compress natural gas. My problem is that the customer wants install a sophisticate Load Sharing Control (LSC) to control individual inlet flow compressor via the driver operating limits and working...
Hello Guys,
I’m working on a new project where there are 6 turbo compressors in parallel, my problem is that the customer wants install a sophisticate Load Sharing Control (LSC) controlling driving operating limits in cascade with the inlet for each compressor via the compressor speed, the...
