Continuous Emission Monitoring
ESC Spectrum designs and tailor CEM systems to meet the toughest monitoring challenges. We construct CEMS in compliance with federal, state, and local regulations based on an in-depth knowledge of the process, monitoring and ancillary hardware, control system, and reporting software requirements involved.
Natural Gas and Midstream
We provide design-build gas measurement systems for the Natural Gas, Liquid Natural Gas and Liquid Hydrocarbon sectors. They are strictly compliant with all Hazardous Area Classifications, including Class I and II, Division I and II and Groups ABCD. They meet all relevant standards: API, ISA, UL, FM, UBC, NELC, CSA and ATEX.
Process Monitoring
Our systems for process control, product quality and process safety applications are deisgned to meet any measurement requirements, from standard to challenging. Our systems can monitor analytes from percent ranges to trace level concentrations. We can couple chemical composition analysis with physical process parameters including flow, pressure, temperature, color, turbidity, viscosity, pH and more.
Flare Gas Monitoring
ESC Spectrum's Flare Gas monitoring systems are designed to operate in the harshest refinery and petrochemical flare applications, including samples with routine water, hydrocarbon liquids, steam injection and high velocity flows. Our systems offer comprehensive, real-time Flare Gas monitoring to The EPA's NSPS Subpart Ja and Refinery Sector Rules,and future Petrochemical industry requirements.
Fenceline and Ambient Air
Many industries are required by regulations, consent decrees and permits to monitor pollutants and toxic gases that cross their fenceline. These include Benzene monitoring requirements for refineries as per the Refinery Sector Rule. Our analyzer and integrated systems are idea for ambient air or industrial hygiene, safety and air quality applications.
Shelters, Racks & Enclosures
ESC Spectrum offers a variety of shelter, racks and enclosures custom-built to fit any application in a variety of industries, including power generation, refinery, petrochemical, pulp and paper, glass manufacturing, metal production, chemical processing, universities, medical centers and more.
ESC Spectrum has decades of experience providing integrated systems for air emissions compliance in various industries and applications.
Our integration specialists are experts in the design and construction process – from understanding permit and regulatory requirements and technical planning to installation, start-up, maintenance, and operation.
