求组一个理论计算问题(关于SO2气体在水中的溶解量)?
遇到个理论问题,烦请盖德们帮忙解答下,谢谢! 4000m3/h的SO2气体(35度),压力15KPa(G),通过一个10m3的水箱,通过排气口排出至后级, 水箱里面的水(32度)以8m3/h的速度置换,那么大概会有多少m3/h的SO2被水吸收,还剩多少 m3/h的SO2排出来??

UF+一级RO+DGS+EDI新型水处理技术?
<P align=left><FONT face=宋体 size=4>昨天在公司听了份EDI产品推广报告,讲到的是EDI想吞掉混床市场的具体操作路线,他们在报告中指出,如果进水在120至800TDS之间则采用UF+一级RO+DGS+EDI工艺优于传统的UF+一级RO+二级RO+混床工艺,这里说明一下,DGS是即膜脱气概念,下面是膜脱气概念的简单说明: </FONT></P> <DIV class=O style="mso-line-spacing: '60 40 0';

求助2010案列下第六题?
用连续常压 精馏塔 分离A、B二组份 混合液 ,其相对挥发度为2.4,饱和状态进料。进料中A组份的浓度为60%(mol),另外还有一股相同组份的进料,其中A组份的浓度为22%(mol),进料量和进料状态与原混合液相同,在该塔适宜塔板位置上加入。若要求塔顶馏出液中A组份浓度为95%(mol),塔釜排出液中A组份浓度为10%(mol),该塔的最小回流比是下述哪个数据? (A)2.97 (B)1.51 (C)2.0 (D)0.92 这个题目到底是分别求回流比,还是把两股合并成一股在求回流比。 2012年的案列下 22题目也是这样的两股进料。 像这样的两股进料在天大和协会教材都没有介绍。翻了下当时学校发化原教材里面也没有提到。 求介绍下这样的两股进料的知识点,和怎么处理、、

甲苯里面的苯乙烯?
各位 亲们, 最近做了一个实验,用光气化的, 甲苯 做溶剂,新鲜的甲苯,后面出现一个 杂质 ,精馏处理不掉,送了MS-GC,后来推测的是甲苯里面有苯 乙烯 , 有点晕了,甲苯的GC检测,纯度没有问题,只有很少小于0.1%的一些杂质,不知道为什么影响这么多,存在的蓄积吗? 求解,,,,谢谢
