This invention relates to a vertically disposed polymerization reactor (2) having a series of essentially circular tray assemblies (10); each tray assembly (10) having a central open vapor chimney (18) and two split-flow paths (26) each split-flow path (26) containing one reverse flow path wherein the liquid polymer flow is reversed by means of a substantially semi-circular turnaround region (24); said trays (10) having a liquid polymer tray inlet (14) and a liquid polymer tray outlet (16) for conducting a flow of the liquid polymer by means of a hyraulic gradient; each tray assembly (10) being open at the top for escape of vapor from the liquid polymer flow to the central open vapor chimney (18); and said trays (10) arranged in vertical disposition one above the other.
摘要:
A process for carrying out mass transfer between a liquid phase (Fl) and a gaseous phase (Fg) in a filled-type column comprising an outer shell (2) in which at least one basket (3a,3b) is housed for containing the filling crossed by said phases is distinguished in that it comprises the step of subjecting said liquid phase (Fl) and said gaseous phase (Fg) to an indirect heat exchange (21) in said at least one basket (3a,3b) through at least one heat exchanger (21) embedded in said filling. In such a way increased mass transfer efficiency between the aforementioned phases is achieved with the consequent possibility of reduction of the size of the column intended to carry out such a process.

Améliorations concernant la détermination et la régulation d'un procédé d'hydrogénation en continu, consistant à obtenir des courbes de viscosité et des courbes d'opacité pour les comparer à des courbes connues d'insaturation d'hydrogène et des caractéristiques de plasticité. Avec un équipement amélioré d'hydrogénation permettant de mettre en oeuvre la réaction d'hydrogénation en continu en combinaison avec des stations de prévention d'auto-oxydation et de désodorisation, la présente invention fournit un procédé global et les commandes pour réaliser une hydrogénation précise d'huiles comestibles.

Improvements in determining and controlling a continuous hydrogenation process comprising the obtaining of viscosity operating curves and opacity operating curves for comparison to known hydrogen unsaturation curves and plasticity characterics. With improved hydrogenation equipment for carrying out the continuous hydrogenation reaction in combination with deodorization and auto-oxydation prevention stations, the present invention provides an overall process and controls for precision hydrogenation of edible oils.
摘要:
The invention relates to a base for a mass transfer column, comprising gas through-openings which are distributed over the base (1) and at least one baffle plate (11) for directing the flow of liquid flowing on the base, said base (1) being loadable with a liquid via at least one inlet (3). The base has at least one inlet (3), at least one separating weir (5) which separates the inflowing liquid into two flows, and at least two outlets (12) or at least two inlets (3) and at least one outlet (12) for the liquid. Each flow flows along a flow path (7; 9) to an outlet (12). The invention further relates to a mass transfer column which contains the base and to a use of the base and the mass transfer column.
摘要:
The present invention provides a multi-structured internal heat exchange-type distillation column comprising at least an outermost heat exchange section, an intermediate section, and an innermost heat exchange section, in which the innermost heat exchange section is isolated from the intermediate section, the outermost heat exchange section is also isolated from the intermediate section, the outermost heat exchange section and the innermost heat exchange section are in communication with one another through at least two vapor tunnel connecting ports, a channel is formed inside the outermost heat exchange section in such a manner that, in a case where at least one of the vapor tunnel connecting ports serves as an inlet for vapor from the innermost heat exchange section into the outermost heat exchange section, and the other vapor tunnel connecting port serves as an outlet for vapor from the outermost heat exchange section back to the innermost heat exchange section, the vapor can smoothly flow in one-way traffic from the inlet toward the outlet, and either the outermost heat exchange section and the innermost heat exchange section, or the intermediate section, is a rectifying section, and the other is a stripping section. The distillation column of the present invention has excellent efficiency of internal heat exchange.
