Gupta, A.

Reliance Industries Ltd., Jamnagar, India

Dr. Ajay Gupta is Assistant Vice President and heads the fixed-bed process development group of refining R&D at Reliance Industries Ltd. in Jamnagar, Gujarat, India. He earned BCh and MS degrees and a PhD in chemical engineering from the Indian Institute of Technology (IIT) in Delhi, India. His experience includes the modeling and simulation of chemical processes, implementation of advanced process control strategies in FCC and crude distillation units in several refineries, development of reactor models for various chemical processes (including effect of scale) and the application of computational fluid dynamics for solving problems in the petroleum refining and petrochemical industries.

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. C., 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. C., 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. C., 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.
