Crude Oil Heat Properties
Crude Oil Heat Properties
(OP)
Hi,
I'm trying to heat the crude oil up from 60 deg. F to 100 deg. F in a riser through a hot water shell exchanger. Can someone help me to find the heat properties of a typical crude oil such as specific heat and film coefficient?
Thanks,
Charles

c = (.0388+.00045t) / (sqrt Specific Gravity)
where:
c = specific heat
t = Temp in degree F
Can't help with film coefficient.

You may check this site to see if it takes care of the file coefficient.

I'm trying to use your formula to calculate the specific heat of the API 24 crude at 80 deg. F as:
S.G. = .91
T = 80 deg. F
C = (.0388 + .00045 * 80)/(.91)^.5
= .07488/(.91)^.5
= .0785
It seems that this number little off from what I expected.
Also, can you let me know where this formula come from so I can put the reference on my claculation.
Thanks,

RE: Crude Oil Heat Properties
I owe you an apology, the formula should be
(0.388+.00045*t) / (Sqrt spgr)
I had a decimal point off.
Your c should be 0.444480624 for the oil
I actually don’t remember where I found the formula originally. The only source I have for it is an old delta heat file I wrote for pumps.
