RELATED WORK EXPERIENCE

Process Engineering Intern, Indian Institute of Chemical Technology, Hyderabad, India (May 2012 – Oct

2012)

Project Title: Production of Boron trifluoride (BF3), TANFAC Industries, India

The purpose of this project is to study a pilot plant in order to establish continuous production of Boron trifluoride

(BF3) from the batch process. This improves the manufacturing capacity of the plant.

• Assisted the engineer in operation of batch process and continuous pilot plant process.

• Supported Project Engineer in implementing and reporting engineering procedures, work instructions,

project schedule and progress in the assigned work area.

• Reviewed material safety data sheets (MSDS) of raw-materials (Hydrofluoric acid (HF), Boric acid

(H3BO3), oleum) and datasheets of equipment such as evaporator, reactor, absorber, distillation column and

cooler.

• Calculated heat and material balance (HMB) for all the unit operations in both the processes to analyze

the consumption of raw-materials, energy and to estimate the yield of the product. Thus, the issues associated

during the production of required capacity of BF3 as per the quality specifications have been identified.

• Proposed and implemented methods to troubleshoot the issues:

Batch process - Arrested entry of impurities, leakages in reactors, handling losses, product losses.

Pilot plant process - Designed and installed the Bubble Column reactor (equipment) to promote gas-liquid

contact (contact between the reactants HF and H 3BO3) and improved the distillation process with packed

column and structured packings.

• Ensured that standards of quality, safety and industry standards and practices are maintained.

Project Title: Vulnerability and Risk Assessment, Liquefied Petroleum Gas (LPG) filling plant, India

Studied various accident scenarios such as catastrophic rupture, pipe line rupture and leak from a vessel in an LPG

filling plant and assisted in calculating the effect distances due to radiation and over-pressure using Process Hazard

Analysis Software Tool (PHAST). Assisted the engineer in the documentation of safety audit report.

Chemical Engineering Intern, Visakhapatnam Refinery, Hindustan Petroleum Corporation Limited (HPCL),

Andhra Pradesh, India (Nov 2011-Dec 2011)

• Studied operation manuals and equipment datasheets of refinery operations. Reviewed the process flow

diagrams (PFD), process and instrumentation diagrams (P&ID) and participated in Hazard and Operability

analysis (HAZOP) and Process Hazard Analysis (PHA) for process safety and risk management. Was familiar

with pumps, piping systems and relief valve sizing and specifications in the plant unit.

• Assisted the engineer in the development of process automation control systems.

• Interfaced with other engineering disciplines and organizations as required within the industry.

• Proposed and implemented new techniques to develop the plant process, to improve the quality of product

thus meeting the specifications required by the company.

• Optimized production process in order to reduce the cost and consumption of energy and also in

accordance with the safety and environmental regulations of the plant.

Energy Engineering Intern, SEE-Tech Solutions Pvt. Ltd, Nagpur, India (May 2011 – June 2011)

Project Title: Energy Auditing, Tatipaka refinery, Oil and Natural Gas Corporation (ONGC), India

In this refinery, crude oil is used as feed to produce products such as Naphtha, Superior Kerosene Oil (SKO), High

Speed Diesel (HSD) and Low Sulphur Heavy Stock (LSHS). The objective of this project is to conduct an energy

audit and then identify and implement measures to conserve energy and to control the operating costs.

• Interfaced with client and assisted in managing client relationship.

• Ensured that project is executed as per the contractual obligations and meet technical, quality and safety

requirements within budget and schedule constraints.

• Coordinated significant project interfaces with third parties, such as other engineering contractors,

vendors, subcontractors in the industry.

• Conducted site inspection and studied the operations that are being carried out in process units. Also,

reviewed the process flow diagrams (PFDs) and piping and instrumentation diagrams (P&IDs).

• Collected design data, operating data, energy consumption data for the equipment such as pumps, heat

exchangers, furnace and cooling tower for investigation.

• Performed calculations to find efficiencies of heat exchangers and furnace by applying energy balance

and replaced some of them to conserve energy. Amount of fuel gas need to be used in furnace is conserved.

• Calculated the flow rates that need to be maintained by the pumps by considering their maximum

efficiencies using the data collected.

• Estimated energy loss in cooling towers. Recommended and implemented side stream filtration technique

to control suspended solid impurities in circulating water and also anti-fouling agents to conserve energy.

• Documented the auditing process and prepared energy auditing report.

RESEARCH EXPERIENCE

Chemical Reaction Engineering, University of Cincinnati (Dec 2013 – Apr 2014)

Designed a non-adiabatic, non-isothermal fixed bed reactor for the production of Phthalic Anhydride from

Naphthalene. The reactor is designed and modeled using Mathematica software tool. Studied the design of batch

reactor, continuous stirred tank reactor (CSTR), tubular reactor, plug flow reactor (PFR) and other catalytic reactors

such as packed bed, fixed bed and fluidized bed reactors.

Fixed-bed Adsorption studies for the removal of herbicide i.e. 2,4-Dichlorophenoxyacetic acid (2,4-D) from

waste water using rice husk ash (RHA-an agro based waste material) as adsorbent (Nov 2012 – May 2013)

RHA characterization – Determined p roximate analysis using gravimetric methods, specific surface area and pore size

diameter using Brunauer–Emmett–Teller (BET), functional groups present at room temperature using Fourier

transform infrared spectroscopy (FTIR spectrometer) and structure and orientation using X-Ray diffraction (XRD).

Used High-performance liquid chromatography (HPLC) and UV-Visible Spectrometer for quantitative determination

of 2,4-D in effluent solution; Breakthrough characteristics of adsorption system were determined by varying

parameters such as flow rate of feed solution, concentration of feed solution and bed height of the column.

Performance of adsorption column was evaluated by fitting the experimental data to well established fixed bed models

namely Bohart-Adams, Thomas and Yoon-Nelson models and characteristic parameters which are basis for process

design at real scale were determined.

Spectrometer (XRF) and gravimetric methods. Various combinations of RPMW and cement were used for making

bricks and optimum composition was determined. Characteristics of bricks such as dry compressive strength using

Compression testing machine, while water adsorption, specific weight, voidage in accordance with American Society

for Testing and Materials (ASTM C 67-03a) were analyzed. Then economic feasibility i.e. project cost estimation,

operating cost analysis, profitability analysis for manufacturing these bricks was studied.
