- The operators have noticed that the performance of the reactor is somewhat different to thedesign specifications and suspect that the thermal cycling may be responsible. The seniorprocess engineer would like you to analyse two periods:- The period when the reactor is initially heated up and held at the operating temperature.- The period after the reactor is taken offline for maintenance and then heated up again.You should consider the effect of the tube expansion on the operating variables and theoverall effect on pressure drop and conversion. Compare these responses to the estimatedperformance according to the design basis.You may include any equations or diagrams that you consider necessary to support yourdiscussion. A numerical solution is not required.Hints: A general consideration of the design method for fixed bed reactors may revealrelationships between operating and performance variables.arrow_forwardThe operators have noticed that the performance of the reactor is somewhat different to thedesign specifications and suspect that the thermal cycling may be responsible.
