摘要： A method of removing inert gas dissolved in liquid ammonia involves evaporating, compressing, and then condensing the liquid ammonia together with the inert gas dissolved therein. Thereby, a product stream of warm liquid ammonia that has been freed of the inert gas is obtained, which is under elevated pressure relative to standard pressure and hence suitable for immediate use in methods in which pure liquid pressurized ammonia is required. If, by contrast, the ammonia is cooled first, for example, below the boiling temperature for ammonia and expanded to standard pressure to store it in tanks as liquid ammonia at low temperatures, it is necessary first to reheat and compress it for further processing operations. Thus the disclosed methods lead to significant energy savings.

摘要： A process for preparing methanol by a methanol synthesis reaction of carbon dioxide with hydrogen may involve a distillation step and a condensation step following the synthesis of a crude methanol. A volatile component and water may be separated off from a methanol-containing product stream, and a gas stream containing a volatile component that has been separated off may be discharged at least partially as offgas. At least part of the gas stream that has been separated off may be recirculated into the methanol synthesis reaction. A plant for preparing methanol can store or utilize electric power generated from renewable energy sources and provide facilities for discharging the offgas stream, which can be purified by catalytic after-combustion. Alternatively, the plant can be configured without discharge of an offgas substream, or the offgas streams are so small that they can be released without treatment into the environment at a suitable position.

摘要： A low-temperature heat utilization assembly may be configured to decouple low-temperature heat from process gas at temperatures below 200° C. and to provide the process gas at a lowered intermediate temperature or at a still further lowered final temperature for at least one subsequent process. In the low-temperature heat utilization assembly the process gas may be fed to a first unit, by means of which the temperature may be lowered to the intermediate temperature. The process gas may in some cases be provided to a heat exchanger stage for further lowering to the final temperature. The first unit is an ORC unit for energy transformation of the heat energy into electrical energy and may be coupled to an electrical consumer unit. The ORC unit may be configured for energy feedback of electrical energy within the low-temperature heat utilization assembly or to a process upstream of the ORC unit.

摘要： An apparatus for the discharge of quenched or unquenched coke from a coke quenching car into a receiving device, providing that there is an extension of the pusher machine beside at least one coke-oven chamber, which is arranged in one line with the coke-oven chambers, and which is to be operated by the pusher machine, and that there is a receiving device behind the quenching car as seen from the coke-oven battery into which the coke can be pushed from the quenching car by the extension, the receiving device preferably being a wharf. A process for the discharge of the hot coke from a coke quenching car into a receiving device is also disclosed. Capacity bottlenecks of the quenching equipment are compensated so that the coke need not stay in the coke-oven chamber after the end of the coking process, or disturbances of the quenching equipment can be compensated temporarily.

摘要： A method for removing high-boiling hydrocarbons from water-soluble solvent flows, wherein said solvent flows are produced in industrial processes which circulate a solvent as a part of the process, and the solvent must be periodically or permanently freed of high-boiling hydrocarbons which influence the quality or the desired properties of the solvent in an unwanted way, and water is added for carrying out the method in a phase separator, so that the high-boiling hydrocarbons are separated off because of their immiscibility with water, and then the water-miscible phase containing water and solvent is returned to the process. According to the invention, the proportion of high-boiling hydrocarbons in circulating solvents in an industrial process can be kept permanently low.

摘要： The invention relates to a method and apparatus for reducing nitrosamines, formed in removal of CO2 from off-gases by means of an aqueous amine solution. A substream of the aqueous amine solution, loaded with nitrosamines, is branched off from a washing fluid circulation and is concentrated by evaporating water and low-boiling constituents. The concentrated amine solution is retained at the boiling point in a unit in which a liquid phase and a vapor phase are in contact to establish a vapor/fluid equilibrium between the phases. The vapor phase is irradiated with UV light, which decomposes nitrosamines entering the vapor phase. Following decomposition of nitrosamines, the concentrated amine solution is recycled to the washing fluid circulation for further use in the scrubber.

摘要： A methane-rich gas from synthesis gas is made in a methane reactor with a row of methanation stages and, at an upstream end of the row of methanation stages, a CO conversion stage. An incoming stream of synthesis gas containing CO and H2 is split into a plurality of partial streams, one of which is fed to the reactor upstream of the CO conversion stage. Each of the other partial syngas streams is fed to the reactor upstream of a respective one of the methanation stages such that methanation takes place in each of the methanation stages and gas exits from the stages and mixes with the partial syngas stream being fed to the next downstream stage. A plurality of partial streams are diverted from a product-gas stream issuing from the furthest downstream stage and are each fed to the reactor upstream of a respective one of the methanation stages.
