Aspen Plus Ammonia Model - UMD

user.eng.umd.edu

Reforming Unit This unit contains two sections, one is primary reforming, and another is secondary reforming. The desulfurized hydrocarbon feed is reformed to hydrogen and carbon oxides in the presence of steam in the primary reformer, and additionally with hot air in the secondary reformer. The reformed gas contains about 0.3 vol% CH4.

lowpass filter G(ω) with cutoff frequency W. In practice, the demodulator shown above should be preceded by a receivebandpass filter that passes s(t) and eliminates out-of-band noise. Frequency Domain Analysis of Operation Remember that b(t) = s(t)2cosωct. So B(ω) = S(ω +ωc)+S(ω −ωc) This translates the sidebands around ±ωc down
