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.

PetroSkills have built a good development plan for Chemical Engineers.

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

I really cannot apply heat, I dont have any heater at the bottom of the Tank.

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?

Thank you very much

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.

1503-44 the pipe runs under seabed for about 20 miles

Constant flow rate is estimated to be 55 MMSCFD

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.
