Networked column compartment model for a tilted packed column with structured packing

摘要

To successfully implement floating liquefied natural gas technology (FLNG), the separation columns on the topside of FLNG must be optimally designed. To this end, a reliable model that can predict column performance in offshore environments is needed. In this study, a networked column compartment model (NCCM), based on 2D-liquid and gas distribution models (LGDM), was proposed as a reliable offshore column model. A pilot-scale experiment for a column with structured packing was conducted to obtain experimental data regarding the absorption performance of the column in offshore environments. The results of the NCCM were compared with the experimental data. With the aid of the developed model, the effect of tilt angles on absorption performance and packed height was quantified.
