TBP, yes, the Hot gas outlet hot side is used to regenerate Propane Treaters, and the sequence cannot reach the design temperature limit of the Heating period.
Hello CHristine, thanks. Great inputs. I have checked the gas composition in and out of the exchanger and it has not changed much. I am supposing there must be some dirt in the exchangers since it has not been taken out of service for maintenance for almost ten years now.
Good morning,
I have a shell and tube Heat exchanger to heat gas to regenerate Propane Treaters. The exchanger is a 35"x20'; design duty is 7.129MMBTU/Hr. I suspect there is a problem with the exchanger because the Hot side ( Chemterm Oil) temperature is 565 F and the Cold side ( Chemterm Hot...
Sorry , you are right I did not provide all the details, it is an insulated big Butane tank for storage. We have a low point nozzle leaking and have to be fixed.
The Tank is currently kept at almost atmospheric pressure, the operating pressure is 30 Inch H2O at -26/24F, the design pressure is 2.5 PSIG at -60 F, designed for 120,000 BBL, and has Vacuum protection . I believe the design code is API650
Good morning,
I am trying to get a Butane Tank to be completely empty due to a leak on te bottom nozzle. Is there any advise on how I can make all the remaining Butane in the Tank to evaporate?
I am trying to set and configure the High High trip of a natural draft Heater stack temperature. What parameters should I take into account? How Can I set this trip set point.
Katmar and LittleInch thanks for your responses. Yeah my standard conditions are 60 F and 14.7 PSIA. I have a compressibility factor of 0.95 and a volume correction of 1.3
I am trying to verify if my time to reduce pressure in a line pack scenario is correct:
Conditions :
Natural Gas
Initial Pressure: 1400 PSIG
Initial Temp: 128 F
Final pressure: 750 PSIG
Final Temperature: 65 PSIG
Pipe Length: 108945 Ft
Pipe Size: 24 inch
If I take out of this pipe 55 MMSCFD, I...
the stabilizer Condensate Reid Vapor Pressure is usually around 10 psi, I have send the raw condensate to be analyzed by the lab. I don't have the raw condenste vpour pressure ath the moment.
I forgot to mention that the LL trip is set for a tube rupture case to protect dowsntream exchanger shell side, but there is also a Pump installed right after the exchanger
We have a Pressure Shutdown Transmitter installed in a pipe to shut on LL pressure scenario, the old trip set point was 105 PSIG, the pipe contains Condensate of about 14MBD, the flow is still the same but we have lower pressure in the system from 150 to almost 85, but now I need to lower the...
