Patent number: 10376833Abstract: The present disclosure relates to a process for capturing carbon-dioxide from a gas stream. In order to capture the carbon-dioxide, a support is provided and potassium carbonate (K2CO3) is impregnated thereon to form an adsorbent comprising potassium carbonate (K2CO3) impregnated support. The adsorbent is activated to form an activated adsorbent. The gas stream is passed through the adsorber to enable adsorption of the carbon-dioxide on the activated adsorbent to form a carbon-dioxide laden adsorbent. The carbon-dioxide laden adsorbent is transferred to a desorber for at least partially desorbing the carbon-dioxide from the carbon-dioxide laden adsorbent by passing a carbon-dioxide deficient stream through the desorber. The partially regenerated adsorbent is returned to the adsorber for adsorbing the carbon-dioxide from the carbon-dioxide. The process of the present disclosure reduces the overall energy demand by partially regenerating the adsorbent.Type: GrantFiled: May 18, 2016Date of Patent: August 13, 2019Assignee: RELIANCE INDUSTRIES LIMITEDInventors: Surajit Sengupta, Vinay Amte, Asit Kumar Das, Satyanarayana Reddy Akuri, Manoj Yadav, Sukumar Mandal, Amit Gohel, Sampath Nerivetla, Kalyan Chandra Nath

Patent number: 9550708Abstract: A process for catalytic conversion of low value hydrocarbon streams to light olefins in comparatively higher yields is disclosed. Propylene is obtained in amounts higher than 20 wt. % and ethylene higher than 6 wt. %. The process is carried out in a preheated cracking reactor having a single riser and circulating an FCC catalyst. The riser is divided into three temperature zones in which different hydrocarbon feeds are introduced. An oxygenate feed is introduced in the operative top zone in the riser. Heat for the endothermic cracking is obtained by the exothermic reaction of converting the oxygenate feed into gas and/or from a regenerator in which the spent FCC catalyst is burnt.Type: GrantFiled: August 14, 2014Date of Patent: January 24, 2017Assignee: Reliance Industries LimitedInventors: Sukumar Mandal, Manoj Yadav, Amitkumar Parekh, Asit Kumar Das, Shubhangi Jaguste, Praveen Kumar Chinthala, Gopal Ravichandran, Mahesh Marve, Ajit Sapre

Patent number: 8685232Abstract: Manufacture of propylene and ethylene in a FCC unit. Each FCC riser comprises an acceleration zone, a lift stream feed nozzle, a main hydrocarbon stock feed nozzle, and an olefinic naphtha feed nozzle. Mixed FCC catalyst comprising at least 2 percent by weight pentasil zeolite and at least 10 percent by weight Y-zeolite is injected at the bottom of each FCC riser. Olefinic naptha is injected through the olefinic feed nozzle, main hydrocarbon stock is injected through the main hydrocarbon stock feed nozzle and lift stream is injected through the lift stream feed nozzle. Lift stream comprises olefinic C4 hydrocarbon stream and optionally steam and/or a fuel gas. Olefinic C4 hydrocarbon steam is cracked in the acceleration zone at 600 to 800° C., 0.8 to 5 kg/cm2 (gauge) pressure, WHSV 0.2 to 100 hr up 1 and vapour residence time 0.2 to 5 seconds.Type: GrantFiled: December 8, 2009Date of Patent: April 1, 2014Assignee: Reliance Industries LimitedInventors: Sukumar Mandal, Asit Kumar Das, Ashwani Yadav, Manoj Yadav, Akhilesh Bhatnagar, Rajeshwar Dongara, Veera Venkata Satya Bhaskara Sita Rama Murthy Katravulapalli

Patent number: 8618344Abstract: A process is disclosed for enhanced recovery of propylene and LPG from the fuel gas produced in Fluid catalytic cracking unit by contacting a heavier hydrocarbon feed with FCC catalyst. In the conventional process, the product mixture from FCC main column overhead comprising naphtha, LPG and fuel gas, are first condensed and gravity separated to produce unstabilized naphtha, which is subsequently used in the absorber to absorb propylene and LPG from fuel gas. However, the recovery of propylene beyond 97 wt % is difficult in this process since unstabilized naphtha already contains propylene of 5 mol % or above. In the present invention, C4 and lighter components from unstabilized naphtha are first stripped off in a separate column to obtain a liquid fraction almost free from propylene (<0.1 mol %) and other LPG components. Such a stripped liquid fraction, after cooling to 20° C. to 30° C.Type: GrantFiled: June 9, 2010Date of Patent: December 31, 2013Assignee: Reliance Industries LimitedInventors: Manoj Yadav, Sukumar Mandal, Asit Kumar Das, Yogesh Gupta, Minaz Makhania, Gobind Tulsi, Shailendra Arora, Shubhangi Jaguste

Patent number: 8451035Abstract: The present disclosure provides an emulator mapping process on a system-on-a-chip (SoC) for debugging. The implementation reduces manual intervention and makes the emulation mapping process very generic and technology independent and hence it reduces overall project cycle time. In the present disclosure, the SoCs containing analog delay locked loops are made suitable for emulation by configuring analog delay locked loop module in parallel with a synthesizable delay logic module. Further, selection logic is provided to select any one of the module at a time.Type: GrantFiled: December 15, 2010Date of Patent: May 28, 2013Assignee: STMicroelectronics International NVInventors: Prateek Sikka, Rajesh Chopra, Manoj Yadav
