Efficiency of a rotary distillation column

Abstract

Determinations of the height equivalent to a theorfltical plate (H.E.T.P.); hold-up, and through-put were made on a rotary distillation column of the Pegra m-Urey-Huffman type having a rectifying section 56 em long and 5.08 cm in diameter. Using 8S rotatinl!; members (1) baskets with fine holes, (2) flat plates, and (3) cones. test s of separating efficiency were made at speeds of rota-

Analytical Distillation

“…The authors claim the presence of high boiling components, either naturally present, or deliberately added, improve the efficiency of separation. Ziolkowski, Filip, and Kawaha (20) studied a column with rotary cones alternating with fixed cones [probably similar to a design of Mair and Willingham (10)]. Increasing speed of rotation of the cones was found to improve efficiency, particularly at higher vapor loads in contrast to the findings of Mair and Willingham in their w'ork.…”
