本人自动化专业,导师化工厂出来的 我在设计一套硫酸生产中的物料计量系统 年产量10万吨的硫酸厂 每小时产生10万立方炉气 导师大怒 说流量不可能这么大,,请问我的计算过程有问题吗 本设计的硫酸产量为每年98.8%的H2SO4200000t则产酸量为 =100000×98.8%×1000/(300×24)=13722.225 kg/h进转化工序二氧化硫含量a=0.09 ,氧气含量b=0.086,进吸收段三氧化硫含量c=0.089,总转化率x=0.98,吸收率η=0.99进转化器标准气量以1小时为基准 V标 = Y×22.4/(98·x·η吸·a)= 35920.52nm3标进入转化器一段炉气温度为430℃,压力为负压10kPa。V实=V标 =102776.27m3炉气成分: SO2=V标×a= 3232.85 nm3标 O2=V标×b= 3089.16 nm3标N2=34855.966-3137-2997.6=29598.51nm3标进入吸收塔的标准通气量以1小时为时基V标 = Y×22.4/(98·x·c)=35597.65nm3标SO3=V标×c= 3168.19nm3标V实=V标 =56938.81m3

10万吨就10方气量???肯定被骂

:dizzy:没看你过程,你光算下你尾气的重量就不对,10万方气,就算是氮气也得100多吨吧,你应该出在单位上了,尤其是你的升和立方之间的换算

5万方面已经足够了呀!

我这里15万风量就有30万。
