Abstract
A curved tubular flow reactor designed for carrying out chemical reactions continuously, for preparing mixtures and as a liquid-phase heat exchanger comprises a plurality of successive bends having alternating directions of curvature.
Claims37
A curved tubular flow reactor, comprising at least one tube having an essentially circular or elliptical cross section, which tube comprises a plurality of curved sections having alternating directions of curvature, and, optionally, one or more straight sections,
- wherein the distance from the start of a curved section to a change in direction of curvature, as measured along the center of gravity of the cross-sectional area of said tube, is no greater than 70 times the diameter of the tube, and wherein
- the ratio of the lengths of straight sections to curved sections of said tube is ≦5.
