Tóm tắt

AbstractIt has been known for some time that many continuous chemical reactors give the greatest conversion when axial dispersion is minimized, i.e., when plug flow occurs. This paper considers the problem of attaining plug flow in continuous flow systems. The geometrical configuration of a tube wound into a helix is suggested us a convenient and efficient means of producing secondary currents which promote plug flow. On the basis of tracer distribution tests and pressure drop data it is conclusively shown that helical coils are far superior to straight tubes or packed beds in minimizing axial dispersion and approaching plug flow.
