问答题 简答题
计算题:已知制氢生产过程中原料气组成如下:C1:0.882C2:0.055C3:0.031C4:0.010C5:0.001H2S:100PPmN2:0.021流量为4000Nm3/h,此时,制氢蒸汽配入量为32.1T/h,求此时的水碳比。
答案
参考答案:
根据已知条件,应先求出原料气的总碳量∑C:
∑C=1×C1%+2×C2%+3×C3%+4×C4%+5×C5%
=1×0.882+2×0.055+3×0.031+4×0.010+5×0.001
=1.13
总碳流量QC为QC=1.13×4000=4520Nm3/h
蒸汽换算成标准状态下的流量为:Fs=32.1×1000×1000/18×22.4/1000=39946.67Nm3/h
H2O/C=39946.67/4520=8.38
