Hi All,

 

I am working on a 3-phase separator design and I need to insulate complete vessel because of climate conditions in Winter. Temperature in winter may go down to -6 degC, minimum temperature need to be maintained inside the vessel is 26 deg C so that there is no hydrate formation or freezing of water takes place.

 

Material of construction of vessel is SA516 Gr 70N+ SS 904L Cald (5mm).

Thickness of vessel is 46 mm.

Vessel dimension: 3800 mm X 14000 mm T/T.

 

Gas flow: 1.93 MMscfd (1049038 kg/hr), gas density: 15.8 kg/m3 & Viscosity :0.012 cP

Oil flow : 448 m3/hr, liq density: 809.2 kg/m3 & Viscosity :2.910 cP
water flow: 631.00 kg/hr, density: 987.40 kg/m3 & Viscosity :0.53 cP

 

Insulation material: as suitable

 

I tried to calculate using normal pipe insulation formulas but I have 3 flows inside the vessel so I am not confident whether it is a correct approach or not.

 

Can anybody please help me how to calculate insulation thickness for vessel.

 

Thank you

 

Venky

I think it's better to start by submitting your trial calculations for comments....

Then... wind conditions are missed and inlet temperature is not defined.
