Marinization of mass transfer columns has been studied for decades, starting in 1947 by Weedmann and Dodge. Numerous papers have since been published for trayed and packed columns under motional conditions. Still today, there is limited information available about the predictive impact of column motion on the fluid dynamics and mass transfer efficiency of industrial-sized marinized columns. Raschig and UOP started a new approach in 2010 to evaluate the performance of random and structured packings during column motion. In a moving pilot plant, columns containing different random and structured packings have been investigated for a wide range of liquid loads with varied constant column tilt and different column motion frequencies. This paper compares the performance of random and structured packings used with different column tilts and motions and will provide information on when to apply one of these product lines.
