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.

Chapter 5 Amplitude Modulation AM was the first widespread technique used in commercial radio broadcasting. An AM signal has the mathematical form s(t) = Ac[1+kam(t)]cosωct where • m(t) is the basebandmessage. • c(t) = Ac cosωct is called the carrierwave. • The carrier frequency, fc, should be larger than the highest spectral component ...

Beams Deflections (Method of Superposition)

wp.optics.arizona.edu

Statically Indeterminate Beams The method of superposition is very useful for the reactions at the supports of statically indeterminate beams. As you may recall, a statically indeterminate beam is a beam with redundant supports (i.e. more supports than are required to maintain equilibrium of the beam).
