Skills and Competencies

Is relief device required here? What are consequences?

Sushant Labhasetwar 6

Outcomes

Addition of relief devices made plant safer, deletion met operations requirement in toxic services and made it economical

Samples of Problems Solved

Sushant Labhasetwar 7

Is long piping compromising safety of API tank? What type of relief device will suit the application?

Outcomes

Selected most suitable type of relief device for the application, met local regulations, generated safe design

Sushant Labhasetwar 8

Are operators safe when vent is ignited?

Outcomes

Optimized size of vent boom by critical analysis of most feasible operating/upset scenarios, located vent boom such that operators are safe from thermal radiation and gas concentrations. Also, optimized number of CO2 cylinders at the platform

Gas In- 5 to 50 °C

Gas Out

Well Fluid In60-90 °C

Well Fluid Out

Two Sources:Associated Gas/Lift Gas

(Design Temperature: 75 °C Downstream)

Am I exceeding design temperature in any case?

Outcomes

Design produced optimum area, saved space on layout and cost

• 8 Cases for Associated Gas / 8 Cases for Lift Gas• Conventional Approach: 3 °C when Gas T = 50 °C • My final design: 7.5 °C approach

Instrument Gas HeaterDouble Pipe Heat ExchangerPurpose: Provide 10 °C Superheat

How can the throughput of batch mixer be increased? Is there anyway to reduce batch time?

Outcomes

Analyzed parameters affecting batch time, set up calculation module to evaluate batch time, validated calculations by comparing with existing batch time, played with parameters to suggest improvement in batch time thereby processing more batches in a day

Sushant Labhasetwar 11

What equations best suit given application?

Selection of heat transfer equations from literature survey

Outcomes

Recommended optimum solution for existing mixer by studying various combinations of cooling media, speed of agitation and jacket design. Also, Utilized optimum configuration for designing new mixer
