  • Publication number: 20240422259
    Abstract: A computer-implemented method for automatically detecting a fraud call. A call request is received from a caller device to initiate a voice call with a called device at a local Public Land Mobile Network (PLMN). The call request is identified originating from a foreign Public Land Mobile Network (PLMN). In response to detecting that a caller ID of the caller device is associated to a local Public Land Mobile Network (PLMN), current location information is requested from a database of the local Public Land Mobile Network (PLMN). If the location information indicates the caller device is attached to the foreign Public Land Mobile Network (PLMN), determining the call request as authentic; and if the location information indicates the caller device is attached to the local Public Land Mobile Network (PLMN), determining the call request as fraud.

  • Patent number: 12006480
    Abstract: The present disclosure relates to methods for processing liquefied waste polymers (LWP) containing diolefins. The LWP feed is supplied to steam stripper A to provide a distillate containing diolefins and naphtha, and a distillate bottom. The distillate is subjected to hydrotreatment B to produce a diolefin depleted distillate which is separated by distillation C to give rise to one or more fractions comprising at least a naphtha fraction, an optional middle fraction and a bottom fraction. Hydroprocessing D of the naphtha fraction gives rise to hydrogenated naphtha which is suitable as a feed for a steam cracker E. Since the distillation bottom, bottom fraction and the middle distillate are predominantly free from diolefins, they can be mixed with crude oil and processed further in oil refinery.
