1、2007-2008学年第二学期2006 级 化学工程与工艺专业化工原理B 卷 参考答案及评分标准一、填空题(每空1 分,共 20 分)1.难溶2.空气的湿球温度3.容易分离4.塔顶有液相回流塔底有上升蒸气5.0 yn+1xn 6.气相液相吸收7.化学吸收8.液相侧的传质阻力9.增高降低10.气液相摩尔流量近似不变按等温吸收过程处理11.厢式干燥器气流干燥器流化床干燥器(或沸腾床干燥器)或喷雾干燥器二、单项选择题(每小题2 分,共 20 分)1.B)2.C)3.C)4.D)5.A)6.B)7.D)8.B)9.B)10.C)三、简答题(每小题 5 分,共 15 分)1.简单蒸馏是一次部分气化与部分
2、冷凝(1.5 分),只能用于混合物的初步分离(1 分)。而精馏则是多次部分气化与部分冷凝(1.5 分),可以得到高纯度的产物(1 分)。2.从质量传递的角度看,吸收过程可以看作由三个步骤组成:(1)溶质从气相主体传递到气-液相界面,即气相内的物质传递;(1.7 分)(2)溶质在相界面上的溶解,由气相转入液相,即界面上发生的溶质溶解过程;(1.6 分)(3)溶质从相界面传递到液相主体,即液相内的物质传递。(1.7 分)3.自由水分和平衡水分的划分依据的是平衡含水量(1 分),湿物料中大于平衡含水量,有可能被湿空气干燥除去的那部分水分为自由水分。等于或小于平衡含水量,无法用相应空气所干燥的那部分水
3、分为平衡水分。自由水分和平衡水分的划分除与物料有关外,还决定于空气的状态(1.5 分)。结合水和非结合水的划分依据是固、液结合力的强弱(1 分),借物理化学力与固体结合的水分为结合水分,固、液间结合力较强。而只是机械地附着于固体表面或颗粒堆积层中的大空隙中的水分为非结合水分,固、液间结合力较弱。结合水和非结合水的划分仅决定于固体物料本身的性质,与空气状态无关(1.5 分)。精品资料-欢迎下载-欢迎下载 名师归纳-第 1 页,共 5 页 -四、蒸馏计算题(共20分)1、(10 分)解:由精馏段操作线方程111RxxRRyDnn知,2 分723.01RR,解得 R=2.61 1 分263.01Rx
