API 650 unanchored liquid-storage tanks shell-plate
Corrosion allowance, if specified, shall be added to calculated API 650 tanks shell and self-supporting roof thicknesses; to minimum nominal thicknesses of bottom and supported API 650 unanchored liquid-storage tanks roof plates; to nozzles and manholes; and to all exposed surfaces of internal structural members and non-removable internals.
The design metal temperature of API 650 unanchored liquid-storage tanks each component exposed to the liquid or vapor being stored shall be the lower of the following:a)The minimum temperature to which the tank contents will be refrigerated, including the effect of subcooling at reduced pressure.b)The minimum metal temperature anticipated when the atmospheric temperature is below the refrigerated temperature (see 4.2.1). The effectiveness of the insulation in keeping the metal temperature above the expected minimum atmospheric temperature shall be considered.
Volatilization is the characteristic of oil. Under normal temperature and pressure, as long as the oil is in contact with air, the surface will volatilize. Through scientific analysis and summary, the causes of oil volatilization loss in API 650 unanchored liquid-storage tanks are: natural ventilation loss, static storage loss, dynamic liquid level loss. In the use of API 650 unanchored liquid-storage tanks, static storage loss and dynamic liquid level loss are common losses.
