Nutter ring is a high efficiency metal random packing high mass transfer efficiency low pressure drop high void fraction Nutter ringEfficiency enhanced by lateral liquid spreading and surface film renewalSuperior surface utilization in mass and heat transfer, allowing shorter packed bed heightsA high performance random packing verified by tests conducted at Fractionation Research InstituteMechanical form provides maximum randomness with minimal nesting
