Modelling the performance of a packed column subjected to tilt

As well as being subject to periodic motion, packed columns on floating production platforms can be exposed to sustained tilt and the process designer needs to be able to estimate the column's performance in this condition. Detailed liquid distribution measurements have been carried out on a tilted packed column and these form the basis of a mass transfer prediction model. This model is able to account for the reduction in measured efficiency under tilt when the effect of gas maldistribution is included.
