  • Patent number: 10378818
    Abstract: A process for producing and purifying a synthesis gas stream that contains CO- and H2-produced from a hydrocarbon-containing feed in a gas production unit. CO2 is separated from the synthesis gas stream and CO is cryogenically separated from the synthesis gas stream. CO2 that makes up 5% to 30% by volume in the synthesis is reduced to less than 10 ppm by volume by temperature swing adsorption. The temperature swing adsorption takes place upstream of the cryogenic separation of CO. The CO2 is adsorbed using a disordered adsorbent bed wherein the adsorbent is cooled by means of indirect heat transfer from the adsorbent to the heat transfer medium during adsorption and the adsorbent loaded with CO2 is heated by indirect heat transfer from the heat transfer medium to the adsorbent to effect desorption of CO2.

  • Publication number: 20190242646
    Abstract: The distillation column system has a high-pressure column, a low-pressure column, a main condenser and a low-pressure-column top condenser. Feed air is cooled in a main heat exchanger and introduced into the high-pressure column. An oxygen-enriched liquid stream is withdrawn from the high-pressure column and introduced into the low-pressure column. A gaseous nitrogen stream is withdrawn from the high-pressure column, warmed in the main heat exchanger and withdrawn as gaseous pressurized nitrogen product. The high-pressure column has a barrier-plate section arranged immediately above the point at which the feed air is introduced. The oxygen-enriched liquid stream is withdrawn from the high-pressure column above the barrier-plate section. A purge stream is withdrawn below the barrier-plate section. The gaseous nitrogen stream, before being warmed in the main heat exchanger, is warmed in a counter-current subcooler in indirect heat exchange with the oxygen-enriched liquid stream from the high-pressure column.

  • Patent number: 10345040
    Abstract: A method for controlling a coupled heat exchanger system having a first heat exchanger block and a second heat exchanger block. A first fluid stream is divided into a first partial current and a second partial current both flowing through the heat exchanger system. A second fluid stream flows through the first heat exchanger block counter to the first partial current. A third fluid stream flows through the second heat exchanger block counter to the second partial current. An intermediate temperature is measured on one of the heat exchanger blocks. The amount of the first partial current and the second partial current is controlled based on the current value of the intermediate temperature. This control reduces the strain on the heat exchangers by changing loads while keeping fluctuations of the intermediate temperature low.

  • Publication number: 20190185332
    Abstract: The invention relates to a method for the synthesis of ammonia, in which a fresh gas consisting largely of hydrogen and nitrogen is compressed via a compressor and subsequently fed to an ammonia converter for conversion into a converter product containing ammonia and comprising hydrogen and nitrogen. Upstream of the compressor, ammonia is evaporated into the fresh gas in order to cool the fresh gas and to produce a cold substance mixture comprising ammonia and the fresh gas. The substance mixture is heated in a heat exchanger against at least one process stream to be cooled, and subsequently compressed via the compressor, to obtain a compressed substance mixture comprising ammonia and the fresh gas. Upstream of the circuit cooler, a gas mixture consisting largely of hydrogen and nitrogen is fed to a substance stream comprising the fresh gas. The constituents of the gas mixture are separated from the converter product and/or from the compressed substance mixture comprising ammonia and the fresh gas.
