Regulation of the pollution emissions from the marine ships and strengthening the development of the related technologies are rapidly taking place. Of those emissions released significantly from the cargo tanks is VOC emission. Tankers that will not emit vapors into the atmosphere without machine that has recovery equipment and related technologies have already been developed. Vapors emitted from tankers to recovery machine is used as fuel in the ships that helps cut down the significant portion of the shipping costs needed for the fuel. With recovery facility, the scrubber includes the number of facilities that collects suspended particles in the gas by a high particulate collection device which sprays the liquid through the nozzle which is typically water. For the development of high-efficient design technique for F.O scrubber, nozzle performance analysis and internal flow characteristics through the PIV experiments were studied.
