chemical engineering. SUBSTANCE: charge element for mass- and heat-transfer columns employed in chemical processes has tubular housing, preferably with triangular cross-section, and also has internal protrusions directed from inside surface of housing. Axial length of tubular housing is less than its width measured from the vertex of triangle to the nearest point on opposite side. EFFECT: improved working characteristics and optimized usage of metal. 6 cl, 6 dwg |
