  • Publication number: 20250288753
    Abstract: A weighing system for medical applications may include a basin that has a base and a sloped sidewall that collectively form a bounded cavity with open top surface that receives and holds the material to be weighed. The basin may be free floating above the weighing device within a restricted range of travel. In some examples, the weighing system includes a thermal treatment device to adjust the temperature of the material in the basin. The rate at which heat is delivered to the basin may vary depending on the weight of the contents in the basin.

  • Publication number: 20250002338
    Abstract: A process for the production of hydrogen comprising the steps of: (i) subjecting a gaseous mixture comprising a hydrocarbon and steam to steam reforming in reformer followed by autothermal reforming with an oxygen-rich gas to generate a reformed gas mixture, (ii) increasing the hydrogen content of the reformed gas mixture by subjecting it to one or more water-gas shift stages in a water-gas shift unit to provide a hydrogen-enriched reformed gas, (iii) passing the hydrogen-enriched reformed gas and an oxygen-rich gas to an oxidation unit containing an oxidation catalyst that converts carbon monoxide present in the hydrogen-enriched reformed gas to carbon dioxide, to form a carbon-dioxide enriched gas mixture, (iv) cooling the carbon dioxide-enriched gas mixture and separating condensed water therefrom, and (v) passing the carbon dioxide enriched gas mixture to a carbon dioxide separation unit to provide a carbon dioxide gas stream and a hydrogen product gas stream.
