AMMONIA SYNTHESIS CONVERTOR

摘要

The improved generally-inverted T-shape converter for ammonia synthesis comprises a horizontal high-pressure vessel on which is positioned a vertical high-pressure vessel with free fluid commnication therebetween. Inside these vessels is placed a low-pressure vessel forming one unit also of inverted T-shape geometry similar to that of the high-pressure assembly. The horizontal part of the reactor contains at least two axially-aligned reaction chambers, within each of which is a catalyst supported on grates forming catalyst beds, and the vertical part contains a heat exchager of which one side is in fluid flow communication with a first one of the reaction chambers, which chambers have serial fluid flow communication, and a second side of the heat exchanger is in fluid flow communication with the second one of said reaction chambers. The space under the catalyst bed of the second reaction chamber is fluidly connected with the second side of the heat exchanger by means of a combined heat-exchanger support and vertical duct resting on the inner surface of the horizontal low-pressure vessel directly, or by means of another support therefor.
