Patent number: 11141707Abstract: An inlet diffuser for the fixed-bed reactor is disclosed. The inlet diffuser comprises a truncated cone adapted to receive a stream of gas-liquid mixture. The truncated cone includes at least one opening formed on a circumference of the truncated cone. Further, the inlet diffuser comprises a vertical baffle plate in each of the openings and at least one horizontal baffle coupled to the truncated cone to absorb momentum of the stream received by the truncated cone. Furthermore, it comprises a cylindrical chamber in fluid communication with the truncated cone and adapted to receive the stream from the truncated cone. The cylindrical chamber includes at least one slot to discharge the stream from the inlet diffuser and a splash plate is disposed at a bottom portion of the cylindrical chamber with apertures to discharge the stream from the inlet diffuser.Type: GrantFiled: June 2, 2020Date of Patent: October 12, 2021Assignee: INDIAN OIL CORPORATION LIMITEDInventors: Pravesh Kumar, Darshankumar Manubhai Dave, Ramesh Karumanchi, Sarvesh Kumar, Madhusudan Sau, Gurpreet Singh Kapur, Sankara Sri Venkata Ramakumar

Patent number: 10900507Abstract: A distribution unit for distributing a multi-phase fluid mixture is disclosed. The distribution unit includes a distribution body defining a first passage, and a first distal body portion having a plurality of first slots. The distribution body includes a second distal body portion having a plurality of second slots distributed on a side wall of the second distal body portion. Each of the plurality of second slots is adapted to accommodate a baffle plate. The second distal body portion includes at least one aperture formed on a bottom wall of the second distal body portion. The plurality of first slots, the plurality of second slots, and the at least one aperture are in fluid communication with the first passage to discharge the flow of the multi-phase fluid.Type: GrantFiled: November 30, 2018Date of Patent: January 26, 2021Assignee: INDIAN OIL CORPORATION LIMITEDInventors: Pravesh Kumar, Kamal Kumar, Darshankumar Manubhai Dave, Ramesh Karumanchi, Madhusudan Sau, Debasis Bhattacharyya, Sanjiv Kumar Mazumdar, Sankara Sri Venkata Ramakumar

Patent number: 10647930Abstract: The present invention relates to a hydrocracking reactor system and a process utilizing the same for upgrading heavy hydrocarbonaceous material to value-added products. Accordingly, an aspect of the present invention includes dispersing a liquid feedstock pre-mixed with a catalyst from top of a reactor vessel to obtain dispersed droplets having a predetermined droplet size less than 500 ?m, introducing a gaseous feed comprising primarily of hydrogen from bottom of the reactor vessel to form a continuous gaseous phase throughout a cross-section of the reactor vessel, and allowing the dispersed droplets to contact the continuous gaseous phase throughout the cross-section of the reactor vessel to form reaction effluent comprising one or more lighter product hydrocarbons. The method may further include removing at least a top portion and at least a bottom portion of the reaction effluent from the reactor vessel.Type: GrantFiled: August 30, 2018Date of Patent: May 12, 2020Assignee: INDIAN OIL CORPORATION LIMITEDInventors: Mainak Sarkar, Darshankumar Manubhai Dave, Ramesh Karumanchi, Madhusudan Sau, Ganesh Vitthalrao Butley, Nepal Vishwakarma, Kamal Kumar, Pravesh Kumar, Sarvesh Kumar, Debasis Bhattacharyya, Sanjiv Kumar Mazumdar, Sankara Sri Venkata Ramakumar
