Working on synthesis of oil field chemicals such as demulsifier or emulsion breaker (i.e. oil soluble and water soluble), winterized pour point depressant, surfactants, corrosion inhibitors etc.

Worked on different projects:Development of cost effective oil soluble dispersed catalyst for slurry hydrocracking and catalytic visbreaking process Development of novel and cost-effective neutralizing amines for CDU overhead corrosion and corrosion in solvent extraction unit of lube refinery Developed neutralizing amines formulation for CDU overhead corrosion (Patent published) High temperature pH based experiments evaluated and optimized the different amines for overhead corrosion. Scaled up neutralizing amines formulation up to 12 Ton and successfully trailed in Vizag refinery (Results showed that 23 % less dose is required as compared to commercial amine) Developed neutralizing amines formulation for corrosion in solvent extraction unit of lube refinery Developed corrosion inhibitor for LPG gas pipeline (Scaled up to 30 Ton and commercialized) Development of poly alpha olefins a Group IV lubricant (Patent filed) Synthesis and process development of Group V Lubricants : Poly ol esters and alkylated naphthalene Developed molybdenum based nano-lubricant as friction modifier Developed 2-Ethylhexanoic acid from C4 aldehyde which is generally used for oil soluble catalyst formulation, poly ol ester formation etc. Developed viscosity improver for lubricants Developed various amines solvents for CO2 absorption Internal olefin sulfonate (IOS) and aromatic sulfonate (AS) surfactants synthesis for EOR applications Pour point depressant (PPD) synthesis for fuel oil

Worked on physico-chemical characterization of petroleum refinery by-products such as slurry oil, aromatic extract, vacuum residues,deasphalted oils, heavy extract etc. Synthesized petroleum pitches from different petroleum by-products bythermal treatment at different temperatures, varying thermal soaking time,nitrogen gas purge rate. Synthesized petroleum pitches from different petroleum by-products byusing different catalysts and different temperatures. Modification/pre-treatment of aromatic streams by solvent extraction andpetroleum residues by de-asphalting. Preparation of mesophase pitches/coke from modified/pre-treated feedstocks. Worked on mixed catalysts for the development of new process for thepreparation of mesophase pitches. Study the surface morphology of pitches by optical microscopy and alsoestablish a relationship between feed stocks composition and surfacemorphology. Worked on up-gradation of clarified slurry oil of RIL by converting intopetroleum pitches (isotropic and mesophase): Precursors for advancedcarbon materials, carbon wool and its carbon composites derived frompetroleum, wax production from MVGO and HVGO from which technologytransferred to Numaligarh Refinery Limited, MIBK dewaxing/deoilingstudies on PWD & foots oil for Digboi Refinery. Worked on “studies on relationship between feed stocks composition andmesophase/semi-coke formation and their surface morphology” in-houseproject (OLP-122019). Development of petroleum derived environmentally friendly mesophasepitches from low value refinery stream clarified oil for use as a precursor foradvanced carbon materials as part of CSIR-800 coursework project.
