Galiakotwala Engineering (Mumbai, India)
Galiakotwala Engineering required stress analysis and design verification of a shell-tube heat exchanger. Stress analysis of the shell and tube heat exchanger was performed to confirm peak stresses during equipment startup, operation and shutdown considering transient heat transfer during start-up and shutdown with acid and steam, and steady state heat transfer for acid only operation maintaining a constant inlet temperature.
What we did:
- Performed heat transfer calculations to determine equivalent convection coefficients for acid (tube side), saturated steam (shell side) and external ambient air (for steady state/transient heat transfer FEA).
- Performed steady state/transient heat transfer and quasi-static FEA of heat exchanger considering dead, internal pressure and thermal loads.
- Determined peak stresses in heat exchanger shell and tube components and verified design compliance with allowable stress requirements (as per standard ASME BPVC Section VIII Division 2).
Outcome:
Avesta Consulting confirmed peak equivalent stresses less than temperature dependant stress limits during start-up, operation and shutdown and verified design compliance with the engineering principles of standard AMSE BPVC Section VIII Division 2.
