Patent number: 11274257Abstract: The present invention provides a process for a production of light olefins and aromatics from cracked light naphtha by selective cracking. The present invention thus provides a process for up grading cracked olefinic naphtha to high value petrochemical feed stocks. This process is based on catalytic cracking in which the catalyst activity is optimized by depositing coke for production of light olefins and aromatics. The proposed process has high flexibility and can be operated either in maximizing olefins as reflected from the PIE ratio or in maximizing aromatics (BTX) at different modes of operation depending upon the product requirement.Type: GrantFiled: September 4, 2019Date of Patent: March 15, 2022Assignee: Indian Oil Corporation LimitedInventors: Subramani Saravanan, Bandaru Venkata Hari Prasadgupta, Prosenjit Maji, Shoeb Hussain Khan, Jagdev Kumar Dixit, Shakti Singh, Reshmi Manna, Madhusudan Sau, Debasis Bhattacharyya, Sanjiv Kumar Mazumdar, Sankara Sri Venkata Ramakumar

Patent number: 10646863Abstract: A spent catalyst distributor for distributing spent catalyst in a catalyst regenerator vessel housing a dense phase catalyst bed and a dilute phase catalyst bed. The spent catalyst distributor comprises a conduit comprising a proximal end and a distal end. The conduit projects horizontally or horizontally and downwardly into the regenerator vessel and includes an opening located at the distal end for introducing the spent catalyst at a first location inside the regenerator vessel. The conduit further includes a plurality of orifices located along a length of the conduit between the distal end and an inner wall of the regenerator vessel for introducing the spent catalyst at a plurality of locations inside the regenerator vessel.Type: GrantFiled: March 12, 2018Date of Patent: May 12, 2020Assignee: Indian Oil Corporation LimitedInventors: Shoeb Hussain Khan, Vikas Badhan, Venkata Hari Prasad Gupta Bandaru, Gautam Thapa, Satheesh Vetterkunnel Kumaran, Debasis Bhattacharyya, Sankara Sri Venkata Ramakumar

Patent number: 10578304Abstract: An apparatus and a method for achieving progressive reduction of flue gas is disclosed. Accordingly, an aspect of the present invention is to provide an apparatus comprising of an orifice chamber having an inlet pipe for receiving the flue gas, a flow region defined downstream of an exit of the inlet pipe and having at least a first section and a second section, and an outlet pipe to disperse a pressure reduced flue gas. The first section defined downstream of the inlet pipe has a flow developer means and at least one auxiliary orifice plate. The second section defined downstream of the first section has a plurality of orifice plates spaced apart along a flow length of the second section.Type: GrantFiled: March 14, 2018Date of Patent: March 3, 2020Assignee: INDIAN OIL CORPORATION LIMITEDInventors: Saidulu Gadari, Manoj Kumar Yadav, Shoeb Hussain Khan, Satheesh Vetterkunnel Kumaran, Debasis Bhattacharyya, Sankara Sri Venkata Ramakumar

Patent number: 10478840Abstract: An apparatus and a method for mixing and atomizing a hydrocarbon stream is disclosed. The apparatus comprises of an inner conduit having a first inlet for receiving the hydrocarbon stream, and a second inlet for receiving a primary dispersion stream. The inner conduit produces a primary mixture comprising the hydrocarbon stream and the primary dispersion stream. The apparatus further includes an outer conduit having a third inlet for receiving a secondary dispersion stream. Further, said inner and outer conduits together define an annular passage. The distal end of the annular passage defines a second set of orifices for allowing the secondary dispersion stream flowing there-through to come in contact with the primary mixture and thereby dispensing the secondary mixture so obtained through an outlet.Type: GrantFiled: March 7, 2018Date of Patent: November 19, 2019Assignee: INDIAN OIL CORPORATION LIMITEDInventors: Shoeb Hussain Khan, Venkata Hari Prasad Gupta Bandaru, Jagdev Kumar Dixit, Gautam Thapa, Satheesh Vetterkunnel Kumaran, Debasis Bhattacharyya, Sankara Sri Venkata Ramakumar

Patent number: 10266459Abstract: A process and apparatus for catalytic cracking of hydrocarbon feedstock employing circulating fluidized bed reactor-regenerator configuration for maximizing the yield of propylene (C3 olefin) is disclosed. The apparatus comprises two reaction zones operating under different temperature and weight hourly space velocity (WHSV), one primary zone for cracking of hydrocarbon feedstock and other as secondary zone for cracking of C4 fraction produced from the cracking of hydrocarbon feedstock in the primary reaction zone, optionally admixed with C4 stream from external source. Two dedicated conduits equipped with valves for control of catalyst flow rate are provided to supply the hot catalyst from a common catalyst regeneration zone wherein the catalyst flowing though conduit connected to the secondary reaction zone is cooled employing a heat exchanging device.Type: GrantFiled: August 21, 2017Date of Patent: April 23, 2019Assignee: Indian Oil Corporation LimitedInventors: Manoj Kumar Bhuyan, Satheesh Vetterkunnel Kumaran, Debasis Bhattacharyya, Shoeb Hussain Khan, Bidyut De, Sudhir Kumar Pande
