Each evaporative condenser and support structure was independently installed in phases allowing the plant to continue production. The overall condenser capacity was increased, the high pressure receiver was relocated and ammonia piping layout was simplified. The old support structure was replaced with a hot dipped galvanized steel structure with access platforms and stairwell.
The objective was to seamlessly replace the evaporative condensers, platform and controls without sacrificing much needed cooling for production.
Scope of Services
The plant conversion consisted of assembling a stand-alone engine room outside of the main building, including a new electrical service, to allow for a seamless conversion of two filling lines during a week-long shutdown. Shambaugh was responsible for the on-site construction management, architectural, civil, structural, process, MEP, refrigeration, and automation disciplines. Highlights include:
- Two phases of rigging and startup of two 8,500 MBH Evaporative Condensers
- Installation of new foundations and galvanized structure including access platforms, handrail and stairway per OSHA
- Relocation of high pressure receiver vessel and simplification of ammonia piping
- New stainless steel motor control panel, power and control wiring and associated programming for operation of evaporative condensers
- Increased remote sump capacity and upsized condenser pumps
- Non-destructive testing for piping and weld inspection
The client now has more capacity and reliable condensers that allow them to operate at lower head pressures, all without losing any valuable production.
