  • Publication number: 20190113278
    Abstract: A method is provided for determining a state of a distillation column having multiple column stages for separating a feed fluid stream into individual fluid components. The state is determined by means of a model in a manner dependent on pressure differences prevailing between adjacent column stages. In the model, both gaseous and liquid flows between adjacent column stages are brought about by the pressure differences prevailing between adjacent column stages. A substance quantity flow characterizing gaseous flow between two column stages is given by {dot over (N)}V·RV=CV·?pV. A substance quantity flow characterizing liquid flow between two column stages is given by {dot over (N)}L·RL=CL·?pL. ?pV,L is a total pressure difference between two adjacent column stages. RV,L is a coefficient of resistance between two adjacent column stages and CV,L is a conductance value of flow between two adjacent column stages.

  • Patent number: 10260985
    Abstract: A method for monitoring and detecting leaks in a pipeline is disclosed. The method is particularly useful in pipelines that are transporting hydrocarbons. Gas enabled photo sensitive particles are fed into the pipeline and when they encounter a leak, change their condition. This change is captured by a detector which transmits the data to an operator that a leak condition exists as well as its location and intensity.

  • Patent number: 10222120
    Abstract: The invention relates to a method and device for generating two purified partial air streams under different pressures. A total air stream (1) is compressed to a first total air pressure. The compressed total air stream (5) is cooled with cooling water under the first total air pressure by way of heat exchange (4, 6). The heat exchange with cooling water for cooling the total air stream (5) is carried out as a direct heat exchange in a first direct contact cooler (6), at least in part. The cooled total air stream (9) is divided into a first partial air stream (10) and a second partial air stream (11). The first partial air stream (10) is purified in a first purification device (18) under the first total air pressure, generating the first purified partial air stream (19). The second partial air stream (11) is re-compressed to a higher pressure (12), which is higher than the first total air pressure.

  • Publication number: 20190063844
    Abstract: The invention relates to a plate-type heat exchanger having at least a first and second heat-transfer block, wherein each block has multiple separating plates, which are arranged parallel to one another, which form a multiplicity of heat-transfer passages for fluids taking part in the heat transfer. The heat-transfer blocks are outwardly bounded by cover plates. A first cover plate of the first heat-transfer block is secured to an opposite second cover plate of the second heat-transfer block. At least one elongate first profile is secured to the first cover plate. At least one elongate second profile running parallel to the at least one first profile is secured to the second cover plate such that the two profiles are opposite one another in a direction parallel to the cover plates. Between the two profiles there is an interspace in which an elongate element is arranged in an interference fit with the two profiles, such that the two cover plates and thus the two heat-transfer blocks are secured to one another.

  • Patent number: 10215183
    Abstract: A method for pressure and temperature control of fluid in a series of cryogenic compressors. An actual speed for each compressor and an actual inlet pressure and actual inlet temperature at entry are determined. The maximum speed for each compressor and a desired inlet pressure for the first compressor is provided. A speed index for each compressor is determined from the maximum speed and actual speed of each compressor. A proportional value is determined from the deviation of the actual and desired inlet pressure. A priority value is determined from the smaller of the proportional value and the smallest speed index. A desired inlet temperature for the first compressor and a desired speed for each compressor are determined from the priority value. The actual inlet temperature is adjusted to the determined desired inlet temperature and the actual speed for each compressor is adjusted to the determined desired speed.

  • Publication number: 20190056176
    Abstract: The invention relates to a process and device for the cryogenic separation of a methane-containing feed gas predominantly consisting of hydrogen and carbon monoxide, that is partially condensed in this case by cooling, in order to obtain a hydrogen-containing first liquid phase predominantly consisting of carbon monoxide and methane, from which first liquid phase, in an H2 separation column that is heated via a circulation heater, a second liquid phase is generated by separating off hydrogen, from which second liquid phase, in a CO/CH4 separation column, a carbon monoxide-rich gas phase is obtained having a purity that permits release thereof as carbon monoxide product. It is characteristic in this case that a low-methane material stream is withdrawn from the H2 separation column and is then applied to the CO/CH4 separation column as reflux.

    Abstract: A method of obtaining helium from a process gas. The process gas is at a pressure less than 15 bar to a first membrane separation stage having a first membrane more readily permeable for helium than for at least one other component in the process gas. A first retentate stream is fed to a second membrane separation stage having a second membrane more readily permeable for helium than for at least one other component in the process gas. Helium is separated from a first helium-containing permeate stream using a pressure swing adsorption to obtain a helium-containing product stream. A second helium-containing permeate stream is recycled to the first membrane separation stage. A purge gas from the pressure swing adsorption is also recycled to the first membrane separation stage.
