    Measurement solution for acrylates speciation

    A customer had a requirement for continuous Ethyl Acrylate monitoring. The process operations emit multiple Acrylate species, all at low concentrations, but only Ethyl Acrylate being reportable to the EA under the terms of the IPC permit. A 204M FTIR analyser was deployed and a chemometric model was built specifically to target Acrylates, with the purpose of separating and accurately quantify the target Ethyl Acrylate species.

    Very large waste gas volumes with low contaminant concentration

    The CTP desorption allows for an especially high concentration factor which, in turn, reduces the cost of ownership and permits an auto-thermal operation (additional burner switched off) even when the contaminant concentration is low.

    ppm Measurement of Oil in Water for the Petrochemical Industry

    Measuring the oil content in water or soil is a specialty of Wilks Enterprise. InfraCal TOG/TPH Analyzers provide on-site ppm measurements to help ensure upstream or downstream wastewater complies with discharge permits to avoid potentially costly fines. There are over 3,000 InfraCal TOG/TPH Analyzers in operation today around the world measuring the oil and grease levels in produced water on drilling platforms, oil content in FRAC water, hydrocarbons in wastewater effluents from refineries, and TPH in soil at remediation sites.

  • Trapped Key Interlocks for Perimeter Guarding

    Our access interlock product range provides solutions to guarding applications by only permitting access once a specified operation has been completed, most commonly shutting off the power. An optional time delay unit adds functionality through denying access to the equipment or area until any residual power has completely stopped, ensuring safe access. Our access interlocks integrate seamlessly with any other KIRK®interlocks already in place, providing you with a complete system. Perimeter guarding has many different uses and advantages, from protecting against dangerous live machinery to enabling access to multiple components at once, as long as they have the same prerequisite sequence. An example of this would be a capacitor bank.

  • Total Reduced Sulfur (S) monitoring

    Total reduced sulfur(s), which include hydrogen sulfide (H2S), methyl mercaptan (methanethiol, CH3SH), dimethyl sulfide (CH3SCH3), and dimethyl disulfide (CH3S2CH3), occur naturally in the environment and can also be present in numerous industrial gaseous streams – petroleum refining, natural gas extraction, and chemical operations like the pulp/paper industry. Hydrogen sulfide is the most prevalent of the total reduced sulfurs, and is commonly found in volcanic gases, marshes and swamps, wetlands and mud flats, sulfur springs and decaying organic matter. Additionally, hydrogen sulfide is produced by living organisms, including human beings, through the digestion and metabolization of sulfur-containing materials. It must be noted that sulfur dioxide (SO2), sulfur trioxide (SO3) and sulfuric acid mist are not included in the determination of TRS, as these are oxidized sulfur compounds and are permitted and monitored separately from TRS.

  • EPR waste minimisation monitoring for wastewater treatment industry

    The EPR regulations have replaced the IPPC regulations and are effective from May 2009 for qualifying companies within the industrial sector and October 2009 within the water sector. They will progressively require industry to minimise waste, reduce product loss and implement improved process control. The legislation will require the operator to self monitor processes and discharges, to demonstrate effective control with particular emphasis on EPR compliance and prevention. The regulating Agency will operate a point scoring system to assess operators under the OMA-3 program and this will be used to identify how well a company is managing their processes and possibly identify areas for improvement. The Environmental Permitting Regulations require industry to install instrumentation (MCERTS approved where available) to report water quality. EPR compliance monitoring may include automatic water sampling, flow measurement, pH, turbidity and TOC water analysis. Industry will need to identify point of source emissions, take steps to correct inefficient control and alarm unacceptable process deviations. Although the legislation focuses on environmental improvement, good housing keeping also makes a lot of sense. Optimisation of process control minimises waste, reduces treatment costs and ultimately saves money.
