  • Patent number: 12268986
    Abstract: A device for conversion of carbon dioxide to oxygen, includes, in order, an axial compressor, a centrifuge compressor, a drum, an air pump, and a housing which provides an accommodating space to house the above assemblies together. The axial compressor and centrifuge compressor inhale the carbon dioxide rich air into the accommodating space, then the carbon dioxide rich air pass through the surface of the reactor drum which cause the carbon dioxide bouncing between the reactor drum and the wall of the accommodating space, the collisions of the carbon dioxide molecules will bend and break the molecule bond between carbon and oxygen to produce oxygen. The device, as mentioned earlier, provides a solution to the greenhouse effect, which eliminates the carbon dioxide and generates oxygen by physical method, and advances a design to enhance the conversion process, which has the potential of being enlargement.

  • Patent number: 12264094
    Abstract: A method for chromium removal from post-tanning wastewater includes the following steps: (a) mixing pretreated post-tanning wastewater with an induction reagent to allow an induction reaction; and (b) adjusting a pH of a mixture obtained after the induction reaction to higher than 7.0 for precipitation; where the induction reagent includes a soluble metal salt. In the treatment method of the present disclosure, pretreated post-tanning wastewater is mixed with an induction reagent, a small amount of neutral chromium complexes remaining in the wastewater are converted into cationic chromium complexes under the action of the induction reagent (that is, a charge property of the chromium complex is changed), and then a pH is adjusted for precipitation to remove chromium, which greatly improves the removal efficiency of chromium in wastewater.

  • Patent number: 12263491
    Abstract: A device for separating blood into a plurality of blood components by centrifugal force includes a first chamber for receiving a blood bag filled with blood to be separated. Each separated blood component is located in a separate portion of the blood bag according to its specific weight. A second chamber receives at least one component bag to be filled with a blood component. The component bag has an inlet opening connected to an outlet opening of the blood bag by a line that has a controllable valve. A displacement body in the first chamber exerts a pressing force onto the blood bag. A control unit opens the valve until a blood component passes into the component bag as a result of the pressing force. The displacement body generates the pressing force with the aid of the centrifugal force and/or with the aid of a spring force.

  • Patent number: 12257588
    Abstract: A centrifugal separator for separating solids from a liquid stream has a rotating drum with a perforated outer wall, an auger in the rotating drum, and a driver that rotates the drum and the auger. The drum has an inlet at a first end for receiving the liquid stream, and a solids outlet at a second end. The auger has a helical flight with an outer edge that is immediately adjacent to an inner surface of the outer wall. The driver rotates the rotating drum to apply a centrifugal force to fluids within the rotating drum such that liquid exits via the perforated outer wall, and the auger is rotated at a different speed such that the auger removes solids from an inner surface of the rotating drum and conveys the solids toward the solids outlet.

  • Patent number: 12252425
    Abstract: The present invention entails dual centrifuges configured to remove suspended solids, silica, and other precipitants from evaporator brine prior to the brine being disposed of via deep well injection. First, the evaporator brine is directed through a highly efficient first centrifuge configured to remove essentially all suspended solids, including very small suspended solids that typically cannot be retained in a filter or other dewatering devices. The centrate from the first centrifuge, depleted in suspended solids, silica and other precipitants, can be disposed of via deep well injection. The first centrifuge also produces a slurry that is directed to a separate centrifuge that produces a second centrate and waste wet cake. The second centrate is recycled and mixed with the evaporator brine and the mixture is directed to the first centrifuge.

  • Patent number: 12202753
    Abstract: Wastewater is remanufactured with ozone in a series of mixing vessels. The ozone is dispersed to both a top and a bottom portion of each mixing vessel, but in different amounts. This creates an electrical potential difference across the height of each mixing vessel which significantly improves the oxidation of organic carbon-based impurities and eliminates H2S and bacteria. Sludge and solids floating to the top of each mixing vessels are removed, as well as sludge and solids settling to the bottom of the mixing vessels. When oil and gas well wastewater is treated in this manner, the resulting treated water is purified and has a high salt content suitable for oil or gas well injection.
