ZDDP Zinc Mitigation

AED provided front-end engineering and detailed design for a refinery to reduce the risk of blending zinc decomposition at high temperatures. Steam heating calculations were performed on 20 tanks and the front-end design was associated with de-superheaters to reduce steam pressure built up in the tanks. To support the zinc mitigation process, AED completed the piping design for the replacement of the steam piping and designed 20+ Safety Instrumented Functions (SIF’s) for the installation of SIS junction boxes and wiring.
