Pulp Mill DCS Upgrade Design, document, configure, and provide start-up support for the migration of a pulp mill operating and monitoring control system in order to improve life-cycle supportability.
Batch Control System Design and configure a control system for two identical batch production lines consisting of process and CIP skids using a single PLC connected to I/O devices utilizing Foundation Fieldbus and Ethernet I/O Communication.
Production and Batch Control System Integrate a new production line and control system including multiple OEM systems and a SQL Server providing for batch recipes, data collection, quality control, and inventory management.
Plant Utilities SCADA System Upgrade Provide services and hardware for a phased upgrade from an obsolete DCS control system based on Siemens APACS and Wonderware InTouch to Allen-Bradley ControlLogix PLCs with Wonderware System Platform.
Alarm Management Document alarm management practices for a pharmaceutical facility consisting of multiple reactor trains and support utilities controlled by DeltaV and Provox DCS systems, Rockwell PLCs, and standalone hard-wired alarms. Analyze systems and provide overall Alarm Management Master Plan.
Independent Alarm System Implement an independent alarm system for an oil and gas refinery using Allen-Bradley ControlLogix PLCs and a CitectSCADA HMI. Provide centrally displayed plant wide alarm monitoring.
Flue Gas Desulfurization Design, configure and provide start-up support for a control system using Rockwell ControlLogix, Siemens APACS, and Wonderware InTouch to control a flue gas desulfurization system at a coal fired power plant.
Reactor Controls Upgrade and Expansion Replace an existing reactor control system using Siemens-Moore MycroAdvantage/APACS with a new Siemens PCS7 solution and expand it to include two reactors in a different part of the plant.
Mini Bioreactor Fed Batch Control System Develop control logic for a prototype mini bioreactor, duplicating existing functionality and developing new code for additional functionality.
C340 Tail Gas Compressor Implement a safety control system using Triconex controller and Citect HMI to control a hydrogen screw compressor. The compressor was designed as an upgrade to the tail gas system, to run in the refinery’s hydro-cracker unit for the production of off-road low sulfur diesel.
