1. A continuous mixing reactor having (a) an outer shell, wherein the outer shell has an interior wall and an exterior wall; one or more inlets for fluids, a hydraulic head (or circulating head) forming one end of the shell, a heat exchange medium header at the opposite end of the shell from the hydraulic head; wherein the shell has a generally cylindrical portion between the hydraulic head and the heat exchange medium header, having a central section and two opposite end sections, the central section having a substantially uniform diameter and each end section is a conical section, and a discharge outlet positioned on a surface of the cylindrical portion; and (b) a hollow circulation tube, open at both ends, extending from the hydraulic head to a terminal end opposite of the hydraulic head and nearer to the heat exchange medium header, and positioned axially within the shell and spaced from the interior wall thereof such that an annular passage is formed between the circulation tube and the shell; and (c) an impeller received within and positioned adjacent to the end of the circulation tube within the hydraulic head of the shell, wherein the impeller provides for mixing of fluid within the reactor, creating a cyclic flow of fluids through said tube; and (d) heat exchange means penetrating the outer shell, wherein the heat exchange means has a tube sheet extending from the head exchange medium header into the open end of the circulation tube opposite of the impeller, wherein the heat exchange means penetrates substantially the length of the central section of the cylindrical portion of the outer shell; characterized as having (1) the end of the circulation tube nearer to the heat exchange medium header terminates at or downstream from a tangential plane extending through the shell at the intersection of the central section and the conical end section of the cylindrical portion of shell; or (2) a flow distribution plate attached to the terminal end of the circulation tube. |
