Senior Principal Engineer Interview Questions

302 senior principal engineer interview questions shared by candidates

Was asked how to estimate Fire case Load for a PSV while any good experienced process engineer would typically bother about controlling cases for Flare design arising out of Power failure, Tower reflux failure, Cooling water failure etc as Fire case is seldom the controlling case for a PSV (designed for multiple cases), Flare lateral or header but more of concern from a temperature stand-point due to temperatures getting closer to Carbon steel limits and requiring superior metallurgy.
