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...
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.
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...
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...
Good morning.
I am trying to design two flow orifices to be able to reduce the DP to protect downstream pressure ( Closed Drain). The pressure in the line is around 1100 PSIG, one line is gas, and the other line is liquid.
The Gas line ( natural gas ) is 12" and the distance from valve to valve...
Can someone please help me finding any reference with regards to the design or the proper height and place that covers the installation of the Vent gas from the Natural Gas fuel heaters?
We have a blower at the base of our flare system. The blower where gases will be burned after mixing on the flare top with butane gases. The Blower is very old, and keeps malfunctioning. Is there any other alternatives of air to supply to the Flare to have a smokeless product. Or if I use air...
If a have a flow of natural gas going through 8 inch diameter pipe about 1500 PSIG and the pipe change the diameter to a half inch diameter (smaller one), How can I determine when the pressure in the 1500 line goes lower than 400 PSIG?
Good day ladies and gents.
I was wondering if there is rule of thumb to determine how much purge gas is needed or required to maintain the Flare System Header Pressure . Anyone knows what are the steps to make those calculations? is there ny API standard to refer to?
Muchas gracias
I have about 1640 ft pipe Carbon steel with condensate around 13000 Barrel at day. The line is operating at 150 PSIG. How long (time) it will take to build up a certain amount of pressure for a blocked flow scenario.
I have a PSV 4"x8" set for 705 PSIG, it is a blocked outlet PSV. The line is a B1 Carbon Steel pipe, with condensate flowing around 15MBPD and at averaqge of 150 PSIG. I am under the impression that the PSV is over sized as the Flow is decreasing exponentially every day. Can this PSV be resized...
Good day all,
We have a Condensate Gas Stabilizer that contains 20 single pass trays to stabilize condensate from an Onshore Field. Our production rate is declining exponentially. I was wondering what process move can we perform to still using this stabilizer under very low flows .
