Abstract:
The invention relates to a device for producing poly(meth)acrylate in powder form, comprising a reactor (1) for droplet polymerisation that has a device (5), with holes through which a monomer solution is introduced, for dropletising said monomer solution so as to produce the poly(meth)acrylate, a gas supply point (13) above said dropletisation device (5), at least one gas extraction point (19) on the periphery of the reactor (1), and a fluidised bed (11), said reactor (1) comprising a region above the gas extraction point (19) that has a constant hydraulic inner diameter and, below said gas extraction point (19), a hydraulic inner diameter that continually reduces. Said reactor (1) comprises a heating unit (31) in the region with the continually-reducing hydraulic inner diameter.
Abstract:
Ein kontinuierlicher Rohrreaktor (3) weist mindestens zwei in Flussrichtung von einzufüllenden Reaktanden (41) hintereinander angeordneten Stufen von Wärmetauschermischern (13) mit jeweils einem Innenvolumen auf, in dem jeweils Wärmetauscherrohre (51) geführt sind. In jeder Stufe ist mindestens ein Mischelement (161-163) vorgesehen, welches im Querschnitt das Innenvolumen über die Länge des Wärmetauscherrohrs (51) ausfüllt und dabei die Wärmetauscherrohre (51) umgibt. In der Überleitung (34) zwischen zwei aufeinanderfolgenden Stufen ist mindestens ein Überleitungs-Mischelement (166-169) angeordnet ist, welches im Querschnitt das Innenvolumen über die Länge der Überleitung (34) ausfüllt.
Abstract:
A mixing device for a fuel reformer for mixing at least two fluids is provided. The mixing device includes at least a first plurality of holes which is arranged along a first row, and a second plurality of holes which is arranged along a second row. The mixing device can be used in a fuel reformer for converting hydrocarbon fuel into hydrogen rich gas by auto-thermal reaction process having a, preferably cylindrically shaped and double walled, housing with two side walls forming a reaction chamber of the fuel reformer, wherein hydrocarbon fuel and an oxidizing agent are mixed by the mixing device.
Abstract:
The present invention relates to a feed distribution device in separation columns and a method of operation. In particular it relates to distillation columns in which the feed stream is substantially liquid phase, or a mixture of gas and liquid upstream of the column, but where the feed vaporizes or vaporizes prior to or as it enters the column. More specifically, the feed distribution device contains a plurality of opening which allow the feed to vaporize prior to or as it enters the column and where the openings are maintained in critical condition during operation. Significant advantage is achieved through the implementation and use of the present feed distribution devices.

Abstract:
A shell-and-tube equipment (10) has a cylindrical geometry and is arranged along a vertical axis (A). The shell-and-tube equipment (10) comprises an upper chamber (12) and a lower chamber (14) connected to a common tube bundle (16) on opposite sides. The upper chamber (12) is provided with at least an inlet nozzle (18) for inletting a first fluid. The tube bundle (16) is surrounded by a shell (20) provided with nozzles (22; 24) for inletting and outletting a second fluid which exchanges heat with the first fluid through the tube bundle (16). The upper chamber (12) encloses at least a distribution device (26) configured for uniformly delivering the first fluid towards the tube bundle (16). The distribution device (26) comprises an annular channel (28) which is arranged around the vertical axis (A) and is in fluid communication with the inlet nozzle (18). The distribution device (26) comprises a plurality of channel modules (30) of circular trapezoid shape, tightly joined together at their respective vertical edges (72, 74) for forming the annular channel (28).
