Process Development/Up-gradation

• A cost effective process based on hydroprocessing route developed for selective mercaptan removal for ATF production with negligible hydrogen consumption
• Dual mode deasphalting Technology developed to enhance refinery distillate yield using LPG as a solvent.
• Identified the blend compositions in pre- and post Delayed Coker scenario for meeting the specifications of Bunker fuel (380 Cst) with minimum quality give away in density at Gujarat Refinery.
• The estimates on product yields, properties, operating conditions, catalyst data, etc. for  seven  cases with varying capacity in the range of 1.3 to 2.9 MMTPA worked out and provided to the licensing partner of INDMAX technology
• IndianOil R&D along with EIL licensed 1.2 MMTPA DHDT unit for Bongaigaon Refinery.
• EIL awarded the job of preparing BDEP for IndAdept^G Unit at Guwahati refinery and the completion schedule is Aug 2011.

Catalyst Research

• R&D developed DHDS catalyst, INDICAT-DH-IV successfully completed a run of 451 days in diesel mode and 52 days in VGO mode in the Plant-13 of CPCL helping CPCL in the process to make BS-III/BS-IV diesel.
• New catalyst and additives namely own Indmax catalyst formulation, DHDS catalyst system for reducing T-95 point of diesel, i-Max Premium ZSM-5 additive for GR Indmax unit, Bottoms upgrading additive for Gujarat FCC unit, value added E-Cat and Alumina support for hydroprocessing catalysts developed .
• i-MAX Premium ZSM-5 additive selected by Panipat Refinery based on NVA against global tender.
• A cost effective ZSM-5 zeolite formulation adopting a template free synthesis approach developed using commercial raw materials.

Technical Services

• Study conducted and recommendations made for use of 10% RFCCU spent catalyst for achieving sulfur reduction in FCC LCN and use of ZSM-5 based additive for reduction of volume of FCC LCN in order to meet BS-IV gasoline specifications in absence of Isomerization unit at Gujarat Refinery.
• Recommended the use of in-house developed i-Max Premium in GR- INDMAX unit, addition of which resulting in improvement of (LPG+Gasoline) yield by about 1 wt%
• Recommended the use of in-house developed IndVi additive in HR-RFCCU with latest feedstock for reduction of CLO by 2 wt% with increase in (LPG+ Gasoline) yield by 1.7 wt%.
• Fifteen cases on revamp of RFCCU at Panipat Refinery for maximization of light olefins along with capacity augmentation with and without R-R section hardware changes worked out and report shared with Refinery
• Recommended the use of in-house developed IndVi additive (5% in the inventory) in BR-RFCCU for reduction of 2-wt% of CLO yield with corresponding increase in TCO yield.
• Evaluated 60 new FCC/RFCC catalysts for IOC refineries Eight failure analyses carried out and recommendations given, Two Residual Life Assessment Jobs completed
• R&D developed Gamma Rays scanning procedure in collaboration with BARC, Mumbai successfully implemented in Panipat, Mathura & Haldia Refineries for scanning of one column each
• Ten crude oil assays generated for Refineries during the year including troubleshooting of reduction in crude thru put as well as crude quality issues at Haldia Refinery.
