Hello,
I've got a job coming up where I'm performing an inspection of a thermal oil heater as part of routine maintenance checking
The heater is horizontal 1500kW gas fed, 2.5 years old, with thermal fluid being pumped around the internal pipe coil
The gas line to the burner will be...
Hello,
I'm designing a steam coil to be used in a batch process still - we are manufacturing the still and the steam coil and the P&ID is being done by others.
The steam inlet line is DN65 and in order to get a sufficient heating area* inside the still a double layered coil is going to be...
Hello,
I'm just about finished the thermal design of a multipass condenser and subcooler system and would like to know if anyone has some real world experience with these units to compare with the theory I've been using:
I'm proposing to use a vertical shell and tube condenser then vertical...
Hello,
A vessel has imploded due to having an insufficient vent diameter and I have been tasked with calculating the new appropriate diameter.
The original vent was 4", 20m long, with 3 elbows, had a fan which wasn't used in the pipe and increased in diameter to 5" after 5m.
The tank...
Hello,
For a 100 m^3 tank would a test pressure of 0.6 barg be sufficient to detect if there was a defect/ leak in any of the welds?
A small overpressure is required for safety concerns as the tank would have to be located in close proximity (>10m) to the workshop as that is where the...
Hello,
I'm using Finglow 3D December 2013 to calculate the minimum shell thickness of a tank which is required to withstand a vacuum pressure of 100 mbar made from SS 304.
I'd like to know the figure that Finglow uses for the yield stress for BS 1501-304-S11 but cannot find it on the...
Hello,
I'm using the standard method outlined in BS 6399-2:1997 to calculate the wind loading on circular vessels and am having some problems determining an appropriate net pressure coefficient.
I work for a manufacturing company that produces atmospheric tanks with a diameters in the range...
Hello,
I am designing a vent system (atmospheric air flowing though a pipe + vent into the tank) to relieve the under-pressure caused from quickly cooling a tank at 85 deg C to 10 deg C (due to a CIP process).
I have calculated using crude thermodynamics that the maximum volumetric flow rate...
