Article Summary Bharat Petroleum BPCL was faced with a serious challenge when it needed to revamp a diesel hydrotreating unit DHDS in Mahul India. Amine wash along with make-up Hydrogen and liquid is sent to the. 13 DHDT-II 8510 14 HMU-IIIIVV kNm3hr 447 15 HS FCCU3 4769 16 PRU-II 932 17 PP-II 1000 18 LCO-X unit 1767 19 DCU-II 7250 20 Ebulated Bed RHCK 9796.
DHDT unit was revamped and its capacity was increased from 29 MMTPA to 33 MMTPA for increased BS-IV HSD production. Meeting BS-IV norms Sulfur 50. With the commissioning of DHDT Paradip Refinery has achieved another milestone in the journey towards commissioning of the refinery.
DHDT is a small unit to process feed LCGO from DCU 84 m3hour or 127 MBSD to produce Naphtha Light Kerosene and Heavy Kerosene and to treat product so that the products have lower sulphur content and nitrogen content and Heavy Kerosene has lower Bromine Number. Petcoke based captive co-generation power plant built first time in an Indian Refinery to utilise Petcoke produced in DCU Integrated Hydrocracker and DHDT unit built for first time in India Foundation field bus technology used across the Refinery. Diesel Hydrotreating DHT occurs in the Hydrotreater Unit and involves the removal of impurities like sulphur and nitrogen from diesel feed in the presence of a catalyst and Hydrogen.
Cracker associated Units Aromatics Polyester Intermediates. Commercialization Grass root unit of 12 MMTPA DHDT is commissioned at IOC-BGR in Aug 2011 for producing diesel. Sanjiv Singh Director Refineries and other senior officials.
Uses hydrogen to desulfurize the naphtha fraction from the crude oil distillation or other units within the refinery. Haldor Topsoe is the Licensor for DHDT and TechnipFMC is the licensor for Hydrogen Generation unit. Nitrogen content in the product can impact to the product color stability.
The other process objectives of the DHDT unit are the stabilization of the wild naphtha generated in the unit such that it can be routed to refinery gasoline pool the amine treatment of the sour off gases produced in the unit 512 UNIT CAPACITY The diesel hydro-treating unit capacity is 35 MMTPA in two chains from feed pre heat upto reaction sections. Maximization of middle distillates primarily ATF Kerosene and HSD in the refinery. 12 As a part of Integrated Refinery Expansion Project IREP BPCL also referred hereafter as Licensee or Owner will be setting up a DIESEL HYDROTREATER DHDT UNIT along with other units in the Refinery.
Stripper for removal of light gases. Remove impurities and polluted elements from diesel fraction with a high efficiency 2. Apart from Refinery units Petrochemical units are also proposed and will mainly contain.
This unit originally installed in 1999 operated with 2530 cracked feed at low pressure 41 barg. Bongaigaon Refinery proposes to implement the DHDT Capacity enhancement Project from capacity of 1200 TMTPA to 1800 TMTPA at its existing refinery. RRP with 9 MMTPA crude processing capacity is under construction at Barmer in Rajasthan state of India by HPCL Rajasthan Refinery Limited HRRL.
Ppm and Cetane number of more than. DHDT unit of Paradip refinery commissioned. Designed as a Zero effluent Refinery.
Of CDU-II unit from 10 MMTPA to 135 MMPTA. DHDT unit is designed to process 2106 MT per day of Straight Run Gas Oil available from CDU unit primarily for removal of sulphur of Gas Oil. The new conditions required a 43 increase in load and a 97 reduction in sulphur.
In the run-up to full commissioning of the Paradip Refinery the Diesel Hydrotreater Unit of Paradip Refinery was commissioned on October 13 2015 by Shri B Ashok Chairman IndianOil in the presence of Mr. 30 DHDT Capacity enhancement project to meet BS-VVI HSD specification. Interested in this product.
To cater to the Crude requirement of Guwahati Refinery arising out of reduced Assam Crude supply Barauni Refinery developed a facility to load LS crude in rakes utilizing the black oil gantry and started dispatching Crude oil from Jan17 to Guwahati Refinery. In a Refinery the Hydrocracking Process which occurs in the Hydrocracker Unit HCU is a type of hydro processing operation where heavy oil is cracked in the presence of a catalyst and Hydrogen to give cleaner fuels.
