Working with a global petrochemical manufacturer AED conducted a series of dispersion analyses (liquid propylene relief valves) for one of their most critical plants in North America. The study determined if associated vapor clouds would contact locations where personnel could be present and provided design recommendations to mitigate hazardous scenarios. By assigning experienced Process Engineers, who coupled their field surveys with cutting-edge software, the team was able to provide a detailed report that was executed efficiently and met client expectations.

As part of a larger, multi-disciplined project execution, AED conducted and managed a site-wide overpressure and exposure assessment for an industrial gas facility. The scope of work included the evaluation of two process buildings with various storage areas, laboratories, and office space. Hazard analysis modeling and a consequence criteria evaluation were used to provide a comprehensive technical report.

AED was brought in by a chemical facility to perform functional safety studies to verify that their systems were in accordance with IEC 61508 requirements. Acting as an SIS (Safety Instrumented System) and SIL (Safety Integrity Level) consultant, our team reviewed the client's design and operating conditons and made recommendations for additional instrumentation required to comply with IEC requirements without burdening the site with over design and increased costs.

AED partnered with a global specialty chemical company to support the installation of a new emissions control system to comply with new state and Federal regulations. As the project developed, AED's team was able to offer an EPCM solution to control costs and expedite the completion of the time-sensitive assignment. The new emissions control unit replaced an existing two-stage wet scrubbing system to provide a cost-effective and fuel-efficient technology reducing overall plant emissions.

AED helped design a new silane transfill area for an industrial gas manufacturer to increase production capacity. An upfront evaluation was conducted by AED's Engineering and Construction Management team to determine the most efficient construction execution path (modular versus stick-built). Ultimately, repurposing an existing structure (including HVAC) allowed the site to minimize capital costs and improve the project schedule.

AED lead the replacement of old Modicon and Provox hardware with a new DeltaV process control system during a three-week turnaround for a chemical plant in Texas. AED provided design oversight, turnaround planning, and construction management services for the replacement affecting over 1200 loops, which included a concurrent reactor replacement. Installation execution and loop checking were completed over a four-day period ahead of schedule. The team faced many construction challenges, most notably the rescheduling of the outage and workspace constraints in the electrical rooms due to Hurricane Florence.

AED designed and commissioned a new PLC system to support a plant upgrade. The new equipment, Allen Bradley Compact Logix hardware, required a detailed design in which AED developed P&IDs and functional descriptions for the PLC hardware. The plant’s operations were running on small outages (only a few hours at a time) which provided narrow windows of opportunity for the switchover to occur. The AED commissioning and construction management team completed the switchover and commissioning activities in two weeks. During this time, the company provided project management services for the overall project, coordinated with vendors and contractors, and managed the project schedule.

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.
