Skills and Competencies

6. 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

7. 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

8. 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 In
60-90 °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 Heater
Double Pipe Heat Exchanger
Purpose: Provide 10 °C Superheat

10. Sushant Labhasetwar 10
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

11. 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
