Continuous emissions monitoring for mercury monitoring

by Opsis AB     based in Furulund, SWEDEN

Waste incinerators, cement plants and power plants need good and reliable measurements of total gaseous mercury. The measurement of total gaseous mercury is a challenge due to chemical reactions and contamination. The installed systems will often require a lot of maintanence still not giving reliable results.

Drill Cuttings

by econ industries GmbH     based in Starnberg, GERMANY

Common drilling procedures for oil and gas, used widely around the world, produce a consistently increasing amount drill cuttings containing oil. In some cases, drill cuttings even contain other hazardous components such as mercury or NORM (Natural occurring Radioactive Material), requiring special attention. Treatment of drill cuttings is therefore beneficial from both an environmental and an economic standpoint, allowing valuable drilling oil to be recovered, and ensuring environmentally sound disposal of the drill cuttings. Our VacuDry® technology is designed to safely separate oil, water and mercury from the solids (including NORM), allowing reuse of the oil and safe disposal of the water, mercury, solids and NORM.

Shredders and crushers for LCD monitor recycling

by Erdwich Zerkleinerungssysteme GmbH     based in Kaufering, GERMANY

According to initial estimates, in Germany about three million LCD monitors will be recycled in the year 2016. However, they often still have backlighting containing mercury and therefore have to be classified as “hazardous waste” in accordance with the German General Administrative Regulation (AVV) and registered in compliance with the German Electrical and Electronic Equipment Act (Elektro G) under category 3. Whereby special conditions must ensure that no risk arises from the mercury for the environment or for humans. However, because of a lack of suitable automated procedures for the recycling of LCD monitors, it was to date only possible to dissemble the appliances laboriously by hand, with the ensuing health dangers for the workers.

Mercury monitoring for measuring mercury content in hair

by Tekran Instruments Corporation     based in Knoxville, TENNESSEE (USA)

Measurement of mercury content in hair is a convenient technique to estimate dietary exposure without having to handle tissues or bodily fluids. As the mercury present in hair is comprised of different mercury species, full speciation of the compounds is needed for complete understanding. Environment Canada published a technique where treating a basic digestion with Cd2+ in the presence of cysteine allowed analysis of inorganic mercury and total mercury using a Tekran 2600 System. Methyl mercury was then calculated by difference. Tekran has over 18 application notes available for Tekran 2600 users.

Mercury monitoring for measuring mercury speciation in air

by Tekran Instruments Corporation     based in Knoxville, TENNESSEE (USA)

Tekran offers the only completely integrated, automated system for measuring mercury speciation in air. The Tekran 2537, when coupled to the Model 1130 and Model 1135 provides a continuous record of gaseous elemental mercury, gaseous oxidized mercury and particle-bound mercury. Over the past 12 years, the Tekran 2537-1130-1135 system has been the most significant tool used to advance the understanding of the fate and transport of atmospheric mercury. See the Expert’s Corner for details about international networks using the Tekran Atmospheric Mercury Speciation System.

Purification of organic & inorganic chemicals for chemical & petroleum refining industry

We offer one of the industry`s widest ranges of activated carbons engineered for the liquid phase of the chemical and petroleum refining industries. These activated carbons are used primarily for the purification of organic and inorganic chemicals, amine, soda ash, antibiotics, and vitamins. In addition, we provide activated carbon products and services that effectively decolorize certain chemicals, such as hydrochloric acid.

Mercury monitoring for mercury flux measurement

by Tekran Instruments Corporation     based in Knoxville, TENNESSEE (USA)

The Tekran 2537 has been used in numerous published studies to measure the deposition or evasion of mercury from natural or contaminated surfaces (i.e. flux measurements). It is anticipated that many mercury flux measurements will be needed in the future to assess the impact of climate change on mercury cycling in the environment. There are two basic ways to do mercury flux measurements. First, the dynamic flux chamber method utilizes a custom enclosure, with controlled air flow, to measure the inlet and outlet concentration over a selected surface to determine the flux over time. Alternatively, the micrometeorological gradient method uses measured concentrations at two levels above a surface. The perfect tool for both flux measurement methods is the Tekran 1110 Two Port Sampler, so the Tekran 2537 can automatically switch between two distinct sampling points. Ask us how we can help you setup a mercury flux system.

Mercury monitoring for on-site remediation

by Tekran Instruments Corporation     based in Knoxville, TENNESSEE (USA)

Fugitive emissions can be a health concern during removal and disposal of mercury-contaminated material at remediation sites. Thus, remediation projects either indoors or outdoors often require on-site, real-time mercury air monitoring with a Tekran 2537. This assures permitted levels are not exceeded during waste processing and human exposure levels are below government regulated toxicity thresholds. Often multiple sites must be monitored continuously. The Tekran 1115 Multi-Port Sampler is the ideal tool for multiplexing the Tekran 2537 for real-time continuous on-site monitoring of mercury fugitive emissions. Please contact us for more information on mercury remediation monitoring.

Mercury monitoring for ocean cruises

by Tekran Instruments Corporation     based in Knoxville, TENNESSEE (USA)

Researchers at Battelle Pacific Northwest Laboratory used a Tekran 2600 on a 2009 ship cruise. Due to the low levels of mercury in water, Tekran provided them with a custom 2600 Event Table to pre-concentrate mercury from multiple samples to push the detection limit lower. When planning an ocean bound cruise, instrument dependability is a paramount concern. At sea, there is no possibility to return instrumentation to the manufacturer for quick repair. The Tekran 2600 has a well deserved reputation for dependability and performance. If any repairs are necessary, the instrument is highly user-serviceable and easy to maintain.

Mercury monitoring for aircraft research measurement

by Tekran Instruments Corporation     based in Knoxville, TENNESSEE (USA)

An examination of the literature shows that the Tekran 2537 is the choice for measurements of mercury aboard research aircraft. Several research groups in Europe and North America have used the Tekran 2537 on an aircraft platform for point source plume studies, free troposphere speciation characterization, vertical profiles, characterizing emission source regions and even the stratosphere (http://www.caribic-atmospheric.com/instrum/hg.html). Normally, the Tekran 2537 requires simple modifications for aircraft studies. Ask us to point you to past research, collaborating research groups and technical information if you are interested in mercury aircraft studies.

Mercury monitoring for manual analysis of air traps

by Tekran Instruments Corporation     based in Knoxville, TENNESSEE (USA)

The Tekran 2600 versatility is evident with the economical and convenient configuration for manual analysis of air samples collected on gold cartridges. Converting the instrument allows calibration by simple injection of gaseous Hg using the Tekran 2505. Once analyzed, the gold cartridges are immediately ready for redeployment.

Hazardous waste treatment solutions for chlorine industry

by econ industries GmbH     based in Starnberg, GERMANY

The mercury cell process is a formerly widely-used production technique for the production of chlorine and caustic soda. The liquid metal, mercury, acts as cathode (negative pole) in this process. In the past, the loss of mercury during the process (to air, soil and water) led to serious health and environmental problems. Therefore, most European chlorine producers have decided to phase out the mercury cell process by 2020. Nevertheless, even today, almost 6000 tons of mercury is used per year for chlorine production in Europe alone. As a result of this, yearly waste outputs contain around 1200 tons of mercury, which are stored on-site or sent off for disposal.
