Thanks StoneCold and Compositepro, Yes, the evenly heat dispersion is excetly what I was concerning with this normal tank heating system since the tank is 75m diameter. The purpose of heating is keep the crude in certain temperature (summer at about 18 C, winter at about 7.5 C) which is the...

Compositepro, Thanks for your input. The tank will be insulated. The reason for not using the glycol heating coil inside of this tank is considered the system maintainance issue. The tank will be expect to operating at mainly full condition most of the time. And also, the required heat is not...

I am working on a crude oil tank heating system which will be used to keeping the crude oil temperature not drop down because of the heat loss to Ambient. The heat loss through the tank wall at the coldest date had been calculated to be about 1 MMBtu/hr. The shell and tube type Glycol/Crude heat...

Thanks for the answer! The viscosity was calculated based on the lab data which has three temperature points. So should be close enough for using it to sizing the line. Regards, Jency

I had charatered the oil by using hysys. The result shows at 40C which is the temperature I was told the crude will be trucked in, the viscosity of the oil is about 2100cp. Does anyone has the experience on handling such high viscosity oil? Is this oil capable to flowing at this temperature...

Stonecold, Thank you for your input. Steam tracing is another consideration. Bolt-on Jacket will be used in this case. Sulfur flow rate is constant, my problem is finding out the right glycol flow rate to make the system working properly both in heat saving and system pressure drop. I did...

Is anyone have a experience for designing an Glycol/Water heat Tracing Jacket system and know the typical length of the jacket could be? I am in the processing of designing an glycol jacket heat tracing system to keep the sulfur line temperature above 138 degC. The sulfur line will be at least...

Thanks guys.

Are there any criteria for the dip angle of Valved Tray Distillation Tower Design? What is the tolerable limit which still allowing the tower working normally? Our case is that a 90ft high 36 traies depropanizer tower is inclined a little bit. The head of the tower moved 3in after it is built...

Montemayor, Thanks for your comments. I do need to get rid of H2S and CO2 at same time. But the main issue is 4000ppm H2S.I got just 2.5%CO2 in the stream. For this small amount gas (5000Sm3/day-25000Sm3/day). Is the amine plant an economical way to sweeten it? I am thinking a altinative...

Hi, I am just working on an sour gas treating project.The problem is the inlet sour gas is under very low pressure situation (65psig @120F)and the composition of the gas is also light ( the heavist component is C3).I am not confident for this simulation, Although I can run it using Hysis. Did...
