A vendor of Gas Turbine Compressor does not reccommend to do a Surge Mapping during Commissioning on our project. They said the reason is because:
"It all depends on how you can manipulate the production at site. You can change volumes and pressures to check the maps, but to perform a surge...
Is there any difference if we do hydrotest at night vs at noon? As we know, at night ambient temp is colder and water is colder. Does it cause different hydotest pressure? I heard from QC Engineer, they did hydrotest at night and hydrotest pressure is lower than it should be. Is it because water...
Morten,
Would you please explain the difference between "true" hysys dynamics & "normal" ss hysys? I am still a newbie, and I have just learned a little bit about dynamics...
U're right, it's like eating an elephant..I am starting to do it step by step:
1. I have simulated depressuring only to...
Morten,
I have to use HYSYS dynamics to get the Pressure vs Time graphic (stripchart). Lets say that I have 3 BDVs that shall be opened in every 5 minutes, so that in the 15 minutes the pressure remains 100psig. Do you have some materials that covers this staggered BDVs simulation?Or something...
I am a fresh grad of chem-eng. And I have an assignment to simulate staggered BDVs. This is because the capacity of flare is limited, so I have to staggered the openings of BDVs. I have to simulate this using HYSYS (combination of depressurizing utility & event scheduler. Have you ever simulated...
