| The technical feasibility of installing an energy-saving heat exchanger onto an existing structure of a petrochemical plant, was investigated. The FE model consisted of a complex industrial steel structure, reactors, hoppers and piping. The vibration measurement exercise involved the use of seismic accelerometers, Laser Doppler Velocimeter (LDV) and a linear displacement string potentiometer. Static and dynamic analyses were performed. |  |
