A column is an important heat and mass transfer equipment, which can be used for distillation, absorption, gas stripping, extraction and other transfer separation process. The commonly used columns include plate columns and packed columns, which are operated under the gravity and have the problems of flooding, furrow flow or bias flow. In this paper, a new column, the swirl tube column, is presented. The swirl tube column is firstly combined super-gravity field (centrifugal force field) with column equipment to enhance mass transfer and absorption process. Through the full-field simulation of a two-stage swirl tube column and experiment, the fluid mechanics performance such as the velocity field and pressure field, pressure drop and flooding critical condition in the swirl tube column, as well as the influence of flowrate and gas-liquid ratio on the absorption performance are studied. Results show that the swirl tube in the column can generate swirling flow, and the flooding problem can be effectively avoided by properly controlling the ratio of liquid to gas, and the absorbing efficiency of the one-staged swirl tube column can reach more than 61%. It is an innovation structural optimization of traditional column equipment. Which has high research and industrial production value.
