VOC Reduction System
The crude oil pressure at the top of loading line is less than ambient pressure since the drop line height is generally lager than 20m and it is up to 27m for VLCC. If the pressure is less than TVP(True Vapor Pressure) of the crude oil, the oil starts to boil and the VOC will be generated.
The generated VOC can be re-condensed by the pressure recovery according to flow into the tank bottom, full re-condensing is not possible since thermal equilibrium is not maintained in the tank. The non re-condensed VOC emits from the vessel causes environmental problem and economical loss also. It is known that 50~200 ton of VOC emits per vessel during loading depending on cargo conditions.
