Abstract: A screw rotor device includes a first rotor having a plurality of helical lobes about its periphery, a second rotor having a plurality of helical flutes about its periphery and a housing with a high pressure port and a low pressure port. The first and second rotors are rotatably mounted within the housing such that the lobes intermesh with the flutes for conveying, in use, a fluid between the high pressure port and the low pressure port. At least one of the rotors has a helical profile that changes along its length such that a gap is described between intermeshing lobes and flutes adjacent the high pressure port which is larger than a gap described between intermeshing lobes and flutes adjacent the low pressure port. The screw rotor device may be used for conveying a fluid.

Abstract: A method of machining, with a formed tool, a first rotor and a second rotor with mutually complementary meshing threads involves rotating a first workpiece about a longitudinal axis of the workpiece. The tool makes one or more passes along the longitudinal axis of the workpiece as the workpiece rotates so as to remove material, thereby forming the flanks of each helix of the first rotor's thread. The value of at least one of the parameters that collectively define the relative position and relative movement of the workpiece and formed tool is varied during each pass so as to vary the lead of the thread. The above steps are repeated for a second workpiece, thereby forming the second rotor. Adjustments are made to at least one of said parameters during one or more of the passes in order to maintain mutually complementary shapes of the threads of the rotors.

Abstract: Disclosed is a method for the production of urea from natural gas, wherein a) natural gas undergoes partial oxidation or autothermal reformation with a gas containing oxygen in a first step and the raw synthesis gas thus arising, consisting essentially of carbon monoxide, carbon dioxide, methane and hydrogen, can be transformed by catalytic conversion of CO and H2O to form CO2 and H2, whereupon carbon monoxide and methane are removed in a multistep gas cleaning process and the hydrogen is converted into ammonia upon addition of nitrogen, and subsequently, b) the ammonia is recombined with the previously separated carbon dioxide in a second step and the ammonia is thus fully converted into urea.

Abstract: Ammonia is catalytically produced from a nitrogen-hydrogen mixture. First of all, a vaporous feed mixture, which comprises 30 to 60 vol-% methanol and 40 to 70 vol-% steam and has a volume ratio steam:methanol of 1 to 3, is passed through at least one bed of a breakdown catalyst at pressures in the range from 30 to 200 bar, the temperatures in the catalyst bed lying in the range from 200 to 500° C. From the catalyst bed, a first gas mixture is withdrawn, which, calculated dry, comprises 40 to 80 vol-% H2 and 10 to 30 vol-% CO2. The first gas mixture is cooled, CO2 is removed in a gas cleaning, and a second gas mixture is generated, which comprises at least 95 vol-% nitrogen and hydrogen, and which is supplied as synthesis gas to an ammonia synthesis for the catalytic production of ammonia.

Abstract: The invention relates to a method for the coproduction of methanol and ammonia from natural gas involving the following steps: 1. Natural gas (flow 1) , steam and oxygen are mixed with one another in a reactor A during which the natural gas is partially oxidized and additionally reformed with the aid of catalysts; 2. The gas mixture removed from reactor A is split into a flow (flow 2) for synthesizing methanol in a unit E and into another flow (flow 3) for producing hydrogen; 3. The carbon monoxide present in flow (flow 3) for producing hydrogen is converted into carbon dioxide inside reactor B with the aid of catalysts and intermediate cooling stages; 4. Remaining impurities such as methane, traces of carbon monoxide and argon are washed out in a cleaning unit D, and hydrogen (flows 6, 8) is fed to the methanol synthesis in unit E and to the ammonia synthesis in unit F; 5.

Abstract: A method for producing ammonia from natural gas, fed to an autothermic reformer with an O2 rich gas. Crude synthesis gas is produced at temperatures of 900 to 1200° C., pressures of 40 to 100 bar and in the presence of a cracking catalyst. The crude synthesis gas is led through a catalytic conversion system to convert CO to H2, thereby obtaining a conversion synthesis gas with a H2 content of at least 55 vol.-% and a CO content of not more than 8 vol.-%. The conversion synthesis gas is subjected to a gas purification to remove CO2, CO and CH4, thereby producing an N2—H2 mixture that is subjected to a catalytic ammonia synthesis. The ammonia produced can at least be partially converted to urea by reacting it with CO2.

Abstract: The invention relates to a system unit for desorbing carbon dioxide and other impurities from highly pressurized methanol. Said system unit comprises at least one or more expansion vessels arranged in succession, at least one heat exchanger, and at least one liquid/gas separator. The inventive system unit contains: a) a line (1) through which the intensely cooled methanol leaving expansion vessel (C) is introduced into the heat exchanger (E) from underneath, and; b) a line (2), though which the heated methanol is drawn out of the heat exchanger (E) from the top, and which serves to connect said heat exchanger to a liquid/gas separator inside of which the remaining carbon dioxide still contained in the methanol is desorbed and separated out to the greatest possible extent. This system unit enables the cold due to evaporation, said cold resulting during the desorption of carbon dioxide, to be obtained inside a heat exchanger and constitutes an important cold energy source for carrying out absorption.
