Abstract
Abstract A reaction vessel, for carrying out thermal reactions, has a heat exchange medium circulated therethrough and through a cooler connected to the vessel. A heating unit is provided, external to the reaction vessel, and is connected to the reaction vessel at two points at different respective pressures, for parallel connection of the heating unit with the normal circulating system of the heat carrier for selective circulation of a regulated at least partial current of the heat carrier through the heating unit. The heating unit may be fluid heated or may be electrically heated, and control and shut-off valve means are provided whereby the heating unit may be selectively placed into operation or cut out of operation. The heating unit also may readily be removed from the reaction vessel.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
153 words
In a reaction vessel for carrying out exothermic chemical reactions, containing a nest of tubes, and having a heat carrier circulated therethrough in a cycle, by a pump, over the external surfaces of the tubes and conducted through a cooling device for extracting the heat absorbed by the heat carrier from the external surfaces of the tubes, the improvement comprising in combination, a heating unit arranged additionally external to said reaction vessel; means connecting said heating unit to said reaction vessel at two points at respective different pressures, for parallel connection of said heating unit with the nOrmal circulating system of said heat carrier for selective circulation of at least a partial current of said heat carrier through said heating unit; and a regulating means in said connecting means controlling connection of said heating unit to said normal circulating system for regulating a partial current of said heat carrier through said heating unit.
Claim 2
Dependent Claim
153 words
In a reaction vessel for carrying out exothermic chemical reactions, containing a nest of tubes, and having a heat carrier circulated therethrough in a cycle, by a pump, over the external surfaces of the tubes and conducted through a cooling device for extracting the heat absorbed by the heat carrier from the external surfaces of the tubes, the improvement comprising in combination, a heating unit arranged additionally external to said reaction vessel; means connecting said heating unit to said reaction vessel at two points at respective different pressures, for parallel connection of said heating unit with the nOrmal circulating system of said heat carrier for selective circulation of at least a partial current of said heat carrier through said heating unit; and a regulating means in said connecting means controlling connection of said heating unit to said normal circulating system for regulating a partial current of said heat carrier through said heating unit.
Claim 3
Dependent Claim
29 words
In a reaction vessel, the improvement claimed in claim 1, in which said regulating means comprises a combined shut-off and control element at the inlet to said heating unit.
Claim 4
Dependent Claim
29 words
