Two-phase countercurrent flow dynamics and simultaneous CO₂ and H₂S removal performance were studied in countercurrent randomly packed-bed columns with fourth generation Raschig super-Rings exposed to static inclination and heaving motion via an unsteady-state comprehensive three-dimensional model. Gas-liquid countercurrent flow displays a gradual deviation to axial symmetry with the increase of angle of the packed-bed column inclination. CO₂ absorption process is negatively impacted in inclined packed-bed columns and the deficit in CO₂ removal performance increases with the increase of H₂S concentration in gas phase. H₂S removal efficiency is marginally reduced and mostly at considerable packed bed inclinations. Under heaving motion of the packed-bed column, an oscillatory two-phase flow and CO₂-monoethanolamine (MEA) absorption process performance develop around the steady-state solution of the column stationary state prior to heaving application. As externally-generated packed-bed column oscillations, the heaving motion impacts more CO₂ absorption because of very high rate constant of the reaction between H₂S and MEA and because the packed-bed column is exposed only to small episodes of time to maximum/minimum heaving acceleration where H₂S removal efficiency can be affected.

通过非稳态综合三维模型，在第四代Raschig超级环承受静态倾角和升沉运动的逆流随机填充床色谱柱中研究了两相逆流流动动力学以及同时去除CO ₂和H ₂ S的性能。气液逆流随着填充床塔倾角的增加而显示出相对于轴向对称性的逐渐偏离。在倾斜的填充床塔中，CO _2的吸收过程受到不利影响，并且随着气相中H ₂ S浓度的增加，CO ₂去除性能的不足也随之增加。高₂去除S的效率会略有降低，并且大多数情况下会在填充床倾角较大的情况下进行。在填充床塔的升沉运动下，在升沉应用之前，围绕塔固定状态的稳态溶液周围会产生振荡的两相流和CO _2-单乙醇胺（MEA）吸收过程性能。当外部产生的填充床色谱柱振荡时，由于H ₂ S与MEA之间的反应速率常数非常高，并且由于填充床色谱柱仅暴露于很小的时间段，从而最大程度地延长了垂荡运动，从而影响了更多的CO ₂吸收。/最小升沉加速度，在此可能会影响H ₂ S的去除效率。
