| 摘 要： | 以三甘醇(TEG)为吸收剂,用空气和水蒸气的混合气体模拟含水蒸气的天然气,在旋转填充床(RPB)中进行脱水实验。研究了TEG流量及纯度、空气流量、RPB转子转速对脱水后空气露点的影响。实验结果表明,空气露点随TEG流量的增加和RPB转子转速的增大而降低;TEG纯度对空气露点的降低有较重要的作用,在RPB转子转速1000r/min、TEG流量600L/h、空气流量10m3/h、空气中水的质量浓度25g/m3的条件下,出口空气露点达到-15℃以下,脱水的平衡度在95%以上。

| Abstract: | Dehydration of air containing water vapor,which simulated wet natural gas,was studied by means of rotary packed bed(RPB) with triethylene glycol(TEG) as absorbent.Effects of TEG flow rate,purity of TEG,air flow rate,RPB rotary speed on dew point of wet air were investigated.Air dew point at outlet lowers with increases of TEG flow rate and RPB rotary speed.Purity of TEG is important for lowering air dew point.Under the optimal conditions: RPB rotary speed 1 000 r/min,TEG flow rate 600 L/h,air flow rate 10 m3/h and mass concentration of water in the air at inlet 25 g/m3,air dew point can be down to-15 ℃ or less and equilibrium point of dehydration is more than 95%.The above specifications can meet the requirements for long-distance transportation of natural gas. |
