注册化工工程师专业考试专题之6:气体吸收? 1.某吸收任务操作业气比,吸收剂进口温度,气体出口浓度,吸收剂进塔浓度,操作压力均确定不变,假定吸收低浓度二组分混合气体,若设计时选用性能更优良的填料,则下列说法不正确的是(BCD) A 所需的传质单元数不变,填料层高度降低;B 所需的传质单元数不变,填料层高度不变;C 所需的传质单元数减少,填料层高度降低;D 所需的传质单元数不变,填料层高度不变; [解析] BCD 传质单元数与相平衡和进出口浓度有关,这些不变,传质单元数不变;选用好的填料,传质单元高度降低,又传质单元数不变,故填料层高度降低,注意题目要求选不正确的! 2.在 填料塔 中用清水吸收混合气中的氨气,当水泵发生吸水量减少时,气相传质单元数将( A ) A 增加 B 减少 C 不变 D 无法确定 [解析] A S=m*G/L;L减小,S增大,故吸收推动力变小,传质推动力增大。 3.在填料塔中用纯溶剂逆流吸收 混合物 中的可溶解组分A。已知气体混合物中A的初始组成为0.06(摩尔分率,下同)。通过吸收后气体的出口组成为0.005,吸收后溶液的组成为0.095,操作条件下气液相平衡y=0.6x,液相和气相分传质系数与液相和气相流量关系为Ky*a正比于G^0.7,Kx*a正比于L^0.7,且吸收过程为气膜控制,HOG =1m,试求: (1)填料层高度减小1半时塔截面气相组成; (2)当液相流量增加时,保持气相流量和气液进口组成不变,则溶质A被吸收的量变化情况是( ) A 增大 B减小 C 不变 D 无法确定 4. 上海某知名 环保工程 公司接受某知名外企委托的处理净化气体混合物中的可溶组分A ,经工艺工程师现场初步调查,气体A的初始组成为0.045,现采用填料塔用纯溶剂逆流吸收,气体出口组成0.018,溶液出口组成为0.088,操作条件下气液相平衡关系y=0.5x,已知此吸收过程为气膜控制,求: (1)气相传质单元数NOG; (2)业主要求在气相和气液进口组成不变的情况下,液相流量增加一倍时,气体吸收后出口浓度不能超过0.006。工艺工程师进行工艺计算,最后得出( )业主要求的指标。 A 能达到 B 不能达到 C 缺少条件 D 无法判断 查看更多0个回答 . 5人已关注
