Most hydroprocessing reactors are fixed-bed reactors comprising several catalyst beds that are divided by quench zones containing mixing chambers that introduce a vapor-quenching medium.
In a refinery or petrochemical plant, certain equipment can create “gray areas” between process engineers and instrument engineers.
A rigorous and accurate performance evaluation of existing equipment is a key factor for the success of a plant revamp study.
