  • Method for removing chlorides from hydrocarbon stream by steam stripping
    Patent number: 9982200
    Abstract: A method for removing chloride impurities from a heavy hydrocarbon stream is disclosed. The heavy hydrocarbon stream is contacted with a stripping medium at a temperature ranging between 100-450° C. and at a pressure ranging between 0.1-2 bar with ratio of the heavy hydrocarbon stream to the stripping medium ranging between 1-30; wherein the temperature is maintained below the initial boiling point of the hydrocarbon stream.
    Type: Grant
    Filed: July 10, 2013
    Date of Patent: May 29, 2018
    Assignee: Reliance Industries Limited
    Inventors: Mahesh Gopalrao Marve, Amit Kumar Parekh, Asit Kumar Das, Rajeshwer Dongara, Devpal Singh Rana, Harender Bisht, Hitesh Kumar Sahu, Jai Kumar Singh, Kalyan Nath, Manoj Yadav, Sampath Nerivetla, Sukumar Mandal
  • Adiabatic regeneration of sulfur capturing adsorbents
    Patent number: 9446384
    Abstract: The present invention provides a process for regeneration of the sulfur capturing spent adsorbents after sulfur capturing using a hydrolyzing agent under adiabatic conditions. In accordance with the process of the present invention hydrolyzing agent is introduced to the spent adsorbent in a controlled manner such that the exothermic heat generated within the adsorbent bed does not rise above the predetermined temperature limit.
