BESTECH engineered an upgrade from an existing hydrogen sulfide (H2S) scrubber to a new caustic scrubber system.
This upgrade included a slag granulation off-gas system with a packed bed scrubber, exhaust fan, recycle pump, and sodium and hydrogen peroxide tanks.
SCOPE
The new system directs off-gases through the caustic scrubber and vents through the existing H2S stack, improving emission handling and safety. An emergency scrubber bypass allows off-gases to vent directly to the stack through the exhaust fan in emergencies, enhancing safety. The redesign eliminated the option to divert gas back to the furnace, simplifying process flow and increasing reliability. This strategy reused some existing equipment and infrastructure, reducing project costs and environmental impact.
BESTECH also developed capital cost estimates for the new system, extending the scope to include electrical and instrumentation design. This involved integrating new flow meters and mass flow meters for improved process control.
OUTCOME
BESTECH’s automation services were crucial for implementing the new scrubber system. The team handled programming, commissioning, and operator training, and developed a system functional specification to guide operations and maintenance. This project ensured compliance and positioned the facility for future operational efficiency and environmental responsibility.
