Rahul Patil is the Lead Research Scientist in the R&D division of Reliance Industries Ltd. He has more than 16 yr of experience in the petroleum refining and petrochemical industries. His professional interests include the debottlenecking and optimization of petroleum refinery and petrochemical units, the application of computational fluid dynamics and process modeling tools, and the modeling and simulation of these units. Patil earned a Bch degree in chemical engineering from the Institute of Chemical Technology, Mumbai, India; and an MTech degree in chemical engineering from the Indian Institute of Technology, Kanpur.

An innovative process for simultaneously producing high-purity benzene and U.S.-grade gasoline from FCC C6 heartcut

Reliance Industries Ltd.: Garg, M.  |  Patil, R.  |  Sapre, A. V.
CSIR-Indian Institute of Petroleum: Kumar, S.  |  Ghosh, P.

Mobile Source Air Toxics (MSAT) II regulations restrict the average benzene level in gasoline sold in the U.S. to 0.62 vol%. In India and in several other countries, benzene in gasoline is presently restricted to 1 vol%. Fluid catalytic cracking (FCC) gasoline contributes to nearly 10%–20% of the gasoline pool in a typical refinery.

Debottlenecking of an extractive distillation column for aromatics recovery: Effect of feed pre-vaporization

Reliance Industries Ltd.: Rewatkar, M.  |  Patidar, P.  |  Patil, R.  |  Gupta, A.  |  Garg, M.

Extractive distillation is one of the most efficient techniques to separate aromatic and non-aromatic hydrocarbons by increasing the relative volatility of the mixture in the presence of a solvent.

Phenomenon of flow distribution in manifolds

Reliance Industries Ltd.: Jain, S.  |  Patil, R.  |  Gupta, A.

Flow distribution is widely encountered in refinery operations, such as air distribution to burners, fluid distribution to parallel heat exchangers and the distribution of reactants in reactors.

Ensure uniformity of air preheater flow to obtain maximum heat transfer efficiency

Reliance Industries Ltd.: Badshahwala, M.  |  Patil, R.  |  Gupta, A.

Uniform flow distribution inside process equipment is desirable for maximizing performance.

Extract the best from your PVC reactor

Reliance Industries Ltd.: Jain, S.  |  Patil, R.  |  Gupta, A.

Polyvinyl chloride (PVC) is the world’s third-most widely produced commodity polymer, after polyethylene (C<sub>2</sub>H<sub>4</sub>)n and polypropylene (C<sub>3</sub>H<sub>6</sub>)n.

Optimize slop-wax bed height in the vacuum unit

Reliance Industries Ltd.: Patil, R.  |  Das, A. K.
Reliance Technology Group, Reliance Industries Ltd.: Yadav, M.

The vacuum distillation (VD) unit in the petroleum refinery separates the heavier fraction of crude oil from the atmospheric distillation unit (ADU) into light vacuum gasoil (LVGO) and heavy VGO (HVGO..

Achieve uniform heat flux in a coker furnace

Reliance Industries Ltd.: Patil, R.  |  Mishra, V. P.  |  Das, A. K.

A delayed coker unit thermally cracks vacuum residue (VR) and converts it into products like liquefied petroleum gas (LPG), naphtha, gasoil and petroleum coke. A majority of the thermal cracking takes..
