325,678. Morgan, G. T., and Tongue, H. Feb. 6, 1929. High-pressure chemical apparatus. - Highpressure reaction vessels, e.g. for ammonia or methanol synthesis are provided with heating or cooling means adjustably positioned in the interior of the vessel but externally accessible so that removal or adjustment can be effected without releasing the pressure in the vessel. Fig. 1 shows a vessel provided with externally open tubes extending inwardly from one wall of the vessel. An electric heating element 5 is adjustably fitted within each tube. In a modification the heating elements are replaced by tubes through which heating or cooling fluid is admitted to the tube 8, the inner tubes being slidable in order to vary the depth to which the fluid penetrates. |
