The metal industry comprises a large variety of different branches, beginning with metal winning and recovery, metallurgy, metalworking and extending to manufacture of machines and devices for which metal finishing and electroplating are indispensable process steps for quality standards. These industries face the difficulties of improved process control and lower environmental stress. AppliTek implements on-line monitoring in specific processes of the metal industry to increase process efficiency and lower...
Metals processing industries employ large, critical assets, the reliability of which is absolutely essential to their business model. An undetected failure of a piece of processing equipment such as a rolling mill gearbox, or a 1000 ton extruder press not only involves the cost of equipment repair and line downtime, but the product quality may be severely impacted. Today more than ever, there is also less redundancy. Oil analysis is a critical aspect of a reliability based maintenance program, and for...
The Opsis monitoring solution in aluminium smelters is based on either DOAS or laser diode technique. The on-line, open-path systems are used for monitoring HF and sulphur dioxide in potrooms, in fence-line applications and in continuous emissions monitoring. Opsis has long experience of monitoring in aluminium smelters.
Steel mills include a multitude of activities that generate gaseous emissions. Besides continuous emissions stack monitoring, the applications in a steel mill also include process mesaurements that provides important data to the operators in order to optimize the steel making process.
The combustion operations the iron and steel processes produce emissions which are subject to strict environmental regulations. Plants are required to monitor and control these emissions. This also provides process efficiency benefits.
Measurement of particulates, SO2, NOX, CO, hydrocarbons and greenhouse gas emissions from the mineral process industries requires careful selection of instrumentation. Ecotech offers a complete monitoring solution tailored to this industry.

The nature of steel manufacturing processes places severe limitations on the monitoring methods that can be used. Aggressive environments combined with high levels of particulates and gases make the choice very limited.
Cooper Environmental's Xact® 640 has the unique ability to generate high time resolution metals measurement in stacks. This unique capability has the potential to qualify as a substitution for the combination of a Hg/ PM CEMs application as well as the potential for a pollution control system feedback loop that could result in the reduction of pollution control consumables. Our systems have been site certified for compliance measurements at hazardous waste incinerator and secondary lead smelter sites.
Measurement of particulates, SO2, NOx, fluorides and greenhouse gas emissions from the aluminium industry requires careful selection of instrumentation. Ecotech offers a complete monitoring solution tailored to this industry.
Hydrogen Fluoride (HF) is a colorless gas that is used extensively in industrial applications. Fluoride monitoring is especially needed for aluminum plants that need to convert HF into fluorine for use in their processes. Any HF that escapes is a cost to the plant, so an HF analyzer is essential to keep track of and prevent the losses.
The Xact® 625i combined with ADAPT software creates the industry's most powerful tool for high time resolution detection of airborne metals. The Xact® 625i measures trace metals at very low detection limits at time resolutions down to 15 minutes. The ADAPT package captures corresponding wind speed and wind direction data, then seamlessly integrates the measurements into wind regression analyses available at the touch of a button. This creates the most single most powerful fence line/ source identification...
