Apparatus for mixing in heat exchanger or carrying out reactions

摘要

Apparatus (1) especially for mixing comprises one or more flow-through elements (2) having a middle-lines (3) in the flow direction. The flow-through elements are formed or arranged so that the curves form by the middle-lines satisfy the following conditions: nu (t) = (-1)t a(t) (cos(2 pi t)-1) c(t)t a(t) sin(2 pi t) nu (t) = position vector in a Cartesian coordination system, t = length of curve (9), - infinite = t = + infinite, t = integral portion of t, a(t) = a curved radius (10) of 0 !a(t)! infinite and c(t)= distance parameter of 0!c(t)! infinite. Also claimed is process of using the apparatus.
