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.

AED executed a project involving the modification of an existing hot oil heating system serving asphalt lines for a major pipeline company. The addition of a new PPA (polyphosphoric acid) tank including dosing pumps was required to run the new truck rack loading lines. The project also included modifications for the asphalt tanks’ heating and mixing systems. AED provided an Electrical + Instrumentation scope of work to include power to the new asphalt and additive pumps, and new remote I/O panels. Detailed designs were completed in three months and the project was finished within an expedited timeframe.

AED responded to an urgent request from a global chemical manufacturer to design a new MDI Drum Thaw facility. AED’s civil/structural team designed a new building to house the drum ovens and coordinated associated permitting. The mechanical and piping team designed the process utilities supply (steam, potable water, condensate return) to the building. The company’s Electrical + Instrumentation team designed the power supply to the MDI building and auxiliaries as well as the instrumentation design for the drum temperature monitoring. The detailed design was executed in three months and the facility was completed in just over eight months from the start of the detailed design. Laser scanning led to zero field rework. AED was commended for their swift actions and quality in the design of the project.
