(ii) introducing the decoking feed at a. mass flux rate at the quench exchanger inlet of >39 kg m?2 second?1, and/or (iii) introducing the decoking feed while maintaining introduction of the first hydrocarbon feed into one or more of the radiant coils in the plurality of radiant coils.

Abstract: An RA (Random Access) procedure is performed by a UE (User Equipment) in cell of a gNB (next-generation Node B) of a mobile network. The UE activates, based on first data, a primary PCell. The UE receives second data from the gNB about one or more secondary PCells for (i) configuring the one or more secondary PCells and for (ii) performing an RA procedure in the one or more secondary PCells. The UE further receives third data from the gNB, indicating which of the one or more secondary PCells is to be activated. After the UE determines that the primary PCell is switched off, it activated the indicated secondary PCell, based on the second and third data. The UE performs an RA procedure in the activated secondary PCell based on the second data.

Abstract: A first communication apparatus of a radio access network transmits paging messages to one or more second communication apparatus in accordance with a paging scheme. The one or more second communication apparatus configure their receivers to be enabled accordingly, while remaining in an operating mode in which they are not fully connected to the first communication apparatus. Small data transmissions may be transmitted from the first to the one or more second communication apparatus after appropriately configuring the receivers of the one or more second communication apparatus to be enabled, while remaining in the operating mode in which they are not fully connected to the first communication apparatus. The required configuration information, in particular times for aperiodic transmissions and/or radio resources used for transmitting and/or the indication for the end of the aperiodic transmission, is transmitted by the first communication apparatus in a paging message.

Abstract: Systems and methods are provided for performing ethane steam cracking at elevated coil inlet pressures and/or elevated coil outlet pressures in small diameter furnace coils. Instead of performing steam cracking of ethane at a coil outlet pressure of ˜22 psig or less (˜150 kPa-g or less), the steam cracking of ethane can be performed in small diameter furnace coils at a coil outlet pressure of 30 psig to 75 psig (˜200 kPa-g to ˜520 kPa-g), or 40 psig to 75 psig (˜270 kPa-g to ˜520 kPa-g). In order to achieve such higher coil outlet pressures, a correspondingly higher coil inlet pressure can also be used, such as a pressure of 45 psig (˜310 kPa-g) or more, or 50 psig (˜340 kPa-g) or more.
