摘要

The device for treating reactants containing condensable components containing synthesis gas of solid, liquid or gaseous carbon at 200-500[deg] C for the production of ammonia, comprises reformer for converting the reactants to synthesis gas, converter arranged downstream of the reformer for converting carbon monoxide to carbon dioxide and further hydrogen contained in the pure synthesis gas from the pollutants such as sulfur compounds and tar precipitation, and gas cleaning plant arranged downstream of the converter for physisorptive removal of carbon dioxide from the produced synthesis gas. The device for treating reactants containing condensable components containing synthesis gas of solid, liquid or gaseous carbon at 200-500[deg] C for the production of ammonia, comprises a reformer for converting the reactants to synthesis gas, a converter arranged downstream of the reformer for converting carbon monoxide to carbon dioxide and further hydrogen contained in the pure synthesis gas from the pollutants such as sulfur compounds and tar precipitation, a gas cleaning plant arranged downstream of the converter for physisorptive removal of carbon dioxide from the produced synthesis gas, and heat exchangers (4, 5, 6) containing heat transmission zone arranged in a row downstream of the reformer and/or converter for indirect transmission of thermal energy contained in the synthesis gas to a process material flow flowing in the heat exchanger. The heat exchangers are mounted vertically among one another in a column with intake of synthesis gas at the column head (2). Between two adjoining heat exchangers, a perforated plate base (7, 8) equipped with a bell shaped cover mounting through a chimney like tube is positioned towards top to an extended central hole with a limber. A baffle plate (15) running under the last heat exchanger is equipped for the separation of condensate and the synthesis gas. The ammonia is extracted in the gas cleaning plant through physisorptive removal of hydrogen-nitrogen synthesis gas produced from carbon monoxide with fluid nitrogen through catalytic conversion at 300-500[deg] C and pressure of 100-300 bar. The perforated sheet base possesses a flat hollow truncated cone. A discharge opening for the synthesis gas and/or the ammonia subjected in the lower part of the column in the area of the baffle plate is connected over a siphon like pipeline (18) with the inlet opening for the process material flow of the heat exchangers. The heat exchanger is tubular heat exchanger, plate heat exchanger, spiral heat exchanger, U-tube heat exchanger, plate-fin heat exchanger and/or printed circuit heat exchanger.
