ABSTRACT:
Packing elements typically used in columns to enhance chemical reactions are illustrated. The packing element may be shaped as a sphere, ellipsoid or any shape of a revolution of a conic. Alternate embodiments illustrated may have faces analogous to crystal shapes. The packing elements have various shapes of drip points. The construction of the element is such that pieces can be folded thus saving assembly time and cleaning time.
