In a FCC revamp, we are getting a higher bottoms temperature in order to meet LCO spec. and product. To control the bottoms temperature, we are proposing the use of a slipstream of the HCO pumparound flowing in a bottoms quench ring in order to prevent coking. Can anyone indicate experiences...
I know this thread was initiated a year ago, but triyng to find the equation as proposed by RJOSVER, I could not find it in the API-521, can you tell me where (Qg = (0.005xd^3)/M^0.565)
Thanks
In a 12 MMSCFD pipeline, some liquid hydrocarbon carry over is now produced (not expected during project), now some possible solutions are trying to be proposed. The whole gas pipeline is within a very isolated area, but a crude line is available. So the initial idea is to recover C5+ and mix...
What I ´ve been doing is to flash the stream at accumulated pressure and 1% vapor. And getting the enthalpy difference between phases. The first 1% is generally accepted because is going to give you the bigger specific volume and smallest vaporization heat (lighter components), i.g., the relief...
Branca,
What I´ve generally done is to place, in addition to a breather/vacuum valve, a blow off hatch. Certainly, a breather valve can fail, so few ounces above is set a blow off hatch to prevent any excess in vaporization and/or missoperation of breather valve.

Have a vessel designed for 10 psig, is horizontal but kind of atmospheric with a free path for venting. Even in a crude service
Does it need ASME stamp?
I understand that ASME stamped is not needed below 15 psig
Thnaks in advance
azertyuiop,
Thanks for your well documented repply, I really feel very confident with my initial thoughts.
In your experience, what is your best recommendation for the 3 way valve ( I mean one inlet from the hopper and 3 outlets, one is for the BB)?SO I can check some preliminary sizes and...
In a polymer plant, a hopper feeds two different filling systems for packing. A big bag filling system has to be added. The existing two filling system are fed by means of a 2-way valve, being each outlet independently controlled. No major room is available below hopper. Before to recommend a...
