Coutor extractor

The Luwesta extractor - 47 is a development of the Coutor extractor. 7 It is essentially a three-stage mixer-settler in which separation is carried out by centrifugal means, in a similar manner to a cream separator. Mixing occurs by means of a spray disc or alternatively when the two phases are collected simultaneously, in a collector disc. Light phase flows through the three stages in succession in one direction, and the dense phase in the opposite direction. 

Eisenlohr (El) has described a three-stage centrifugal extractor based on an early design of Coutor (C6) and arranged in a vertical position, normally operated at about 3,800 r.p.m. The maximum capacity of the... 

The Luwesta (Centriwesta) extractor is a development from Coutor [Eisenlohr, Ind. Chem., 27, p. 271 (1951)]. This centrifuge revolves about a vertical axis and contains three actual stages. It operates at 3800 rotations per minute and handles approximately 5 mVh (1300 gal/h) total liquid flow at 12-kW power requirement. Provision is made in the machine for the accumulation of solids separated from the liquids, for periodic removal. It is used, more extensively in Europe than in tlie United States, for the extraction of acetic acid, pharmaceuticals, and similar products.
