Ambient Air Monitoring System

Industry: Refining

Location: Port Arthur, TX

Client Benefits: Replaced an outdated system with maintenance issues. A study was completed to ensure proper coverage for safety.

Scope Description: 

BGS developed Phase 3 (+/-10% scope development  and TIC estimate) and completed Phase 4 detailed engineering and design for  installation of an ambient air monitoring system consisting of approximately  250 MSA gas detectors and 15 flame scanners for the facility. The cost for the  project was $3.4MM.

Design activities included installation of 5  Allen Bradley (AB) PLC panels on the units, fiber optic communications  highways, and raceway systems for connection of detectors to the AB panels. Project  requirements included redundant feeders to each panel along with installation  of Kepco power supplies in purged and cooled enclosures. BGS provided instrument  specification sheets as well as specification of electrical infrastructure for  the project.

The BG Automation scope included developing  control console alarms, operator interfaces and historization. We also  interfaced with General Monitors for development of Allen Bradley programming  and interface with the primary control system, performed a FAT at General  Monitors in California and provided onsite startup/commissioning assistance.

The project was completed on time and on  budget.  This project has become the  standard for Koch plants.
