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

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

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.

Determine root causes of undesirable petcoke properties from the DCU

Gupta, A., Daggupati, S., Bisht, H., Mandal, S., Das, A. K., Reliance Industries Ltd.

The delayed coking unit (DCU) is the technology of choice for the upgrade of heavy hydrocarbon residues—i.e., bottom-of-the-barrel upgrading.

Phenomenon of flow distribution in manifolds

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

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.

An optimized approach to choosing solvent for the liquid-liquid extraction process

Gupta, A., Jain, S., Reliance Industries Ltd.

Liquid-liquid extraction (LLE) is a traditional method used for separating a specific component (solute) from the carrier liquid phase.

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

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

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

Extract the best from your PVC reactor

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

Polyvinyl chloride (PVC) is the world’s third-most widely produced commodity polymer, after polyethylene (C2H4)n and polypropylene (C3H6)n.

Choose the most appropriate modeling approach for reactors

Jain, A. A., Gupta, A., Reliance Industries Ltd.

The efficient operation and design of any reactor depends on the know-how regarding the chemical reaction and the hydrodynamics inside the reactor.
