Pergunta de entrevista da empresa Air Products
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.
Resposta da entrevista
Sigiloso
Answered it correctly but was rather surprised at the nature of the question as this was not expected to be asked to an experienced mature Process Design Engineer with 25+ years of experience and also indirectly reflected that although the topic was related to PSV and Flare design, the focus on the big picture related to Flare design was missing.
