Projects – SimpleHg

Previous and Current Projects

SimpleHg is a leader in maintaining, repairing, improving, and modifying the mercury emissions monitoring systems to achieve the highest performance and operating standards in the industry. A few of the transformative stories are shown here.

Conversion from Process Monitor to Compliance Hg CEMS

Relocated monitoring equipment from inside stack into CEMS building with modification and replacement of components for transformation to compliance monitoring system.

Hg CEMS for Real Time Emissions and Carbon Rate Controls

Recommissioned mothballed mercury monitor and installed missing instruments to complete system for injection rate feedback to activated carbon systems.

Portable Hg CEMS as Backup for Hg trap Compliance System

Installed two portable Hg CEMS to maintain compliance and reduce downtime when sorbent trap system was broken.

Process Hg Monitor to determine new mercury control Strategy

Installed portable Hg CEMS in stack when recent boiler work significantly changed mercury capture characteristics with risk of noncompliance to standards.

Hg Probe Modifications to improve accuracy and performance

Completed probe cleaning, troubleshooting, repair, and replacement of broken pieces and malfunctioning parts.

Hg CEMS Maintenance and Repair at Cement Production Plant

Performed maintenance and calibrations for a process Hg CEMS installed at main exhaust stack and improved performance of chlorine delivery for integrity tests.

Real time Process Monitor to diagnose Hg capture problems

Recommissioned Hg CEMS with replacement probe to capture real time emissions from a stack downstream of a wet scrubber.

Mercury Testing for Speciation Study at Cogeneration Plant

Installed Hg CEMS at the outlet of the air heater for elemental and oxidized mercury concentrations from a circulating fluidized bed (CFB) boiler.

Mercury Testing for Environmental Study at Steel Mill

Unique installation to sample mercury from a mixing chamber that combines the gas from three baghouse exhaust stacks.
