Publication number: 20250136531Abstract: Processes integrating electric heaters or other heating sources for heating of liquid and two phase hydrocarbon streams resulting in reduced CO2 emissions are described. The processes shift a portion of the fired heater duty to an electric heater or other heat source. All or a portion of a vapor stream from a two phase separator is heated or superheated by an electric heater or other heat source to provide sufficient temperature that the heated/superheated vapor stream acts as a heat source to a bottom or side draw stream from a column. The preheated bottom or side draw stream is sent to the fired heater.Type: ApplicationFiled: October 30, 2023Publication date: May 1, 2025Inventors: Chintan Surendra Shah, Manoj Kumar, Pankaj Kumar Singh, Amit Munjal

Patent number: 12026175Abstract: Methods and apparatuses are described for automated latency-aware purging of database records. A server determines a synchronization latency between a storage database and an online transaction processing (OLTP) database. When the synchronization latency is below a predetermined threshold, the server identifies a first database object in the OLTP database and selects database records to be purged from the first database object based upon a data purge instruction set. The server identifies a second database object in the storage database that corresponds to the first database object and selects database records in the second database object based upon the data purge instruction set. The server purges the database records from the first database object in the OLTP database when a characteristic of the database records to be purged from the first database object matches a characteristic of the database records selected in the second database object.Type: GrantFiled: December 22, 2022Date of Patent: July 2, 2024Assignee: FMR LLCInventors: Pankaj Kumar Singh, Kinjal Desai, Midhun Gandhi Thiagarajan
