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...
Petrochemical production plants suffer from repeated operational disruption caused by undesired fouling, corrosion and foam problems. The consequences are high operating costs and occupational safety concerns. Our dedicated treatment programs help to secure a failure-free operation of your plants and decisively contribute to a considerable reduction of the total operating costs.
Natural gas often contains mercury at concentrations that vary from below 1 to above 10000 µg/m³. Mercury is both toxic and potentially damaging: it can corrode or embrittle common gas plant components. Gas processors require safe, reliable and effective mercury removal process solutions in order to achieve requisite sales gas quality specifications and protect cryogenic equipment. Our monitoring solutions are used to detect and precisely measure mercury levels in natural gas at various locations...
REMOTOX® has proven to remove high levels of mercury from scrubber solutions preventing re-emissions. Additionally, it has proven to capture and stabilize lead, copper, thallium, cadmium, nickel, zinc, iron, silver and other metals commonly found in power plant waste and scrubber wastewater.
The Challenge: Managers of petrochemical facilities today are faced with striking a difficult balance between optimizing the operating the refinery to maximize profits and complying with increasingly stringent environmental regulations governing air and water emissions from the facility. Jacobi fully understands the scale and nuances of refinery operations, and we have developed a full range of activated carbons to meet every challenge in typical refinery operations.
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...
For the removal of mercury emissions from flue gas streams, Calgon Carbon`s specialty PAC products are proven industry performers. These industries include: Coal-fired electric power plants, Cement, Boilers.
Flue Gas Desulfurization (FGD) involves the removal of sulfur dioxide and other acids from flue gases. Typical sources of acid gases include fossil fuel boilers, waste combustors, and other industrial applications such as refining and smelting. The Macrotek wet and dry FGD systems can achieve over 99% acid removal by using a variety of reagents, including caustic, sodium carbonate, lime and limestone, and waste alkaline solids or liquids.
FGD (Flue Gas Desulfurization) involves the treatment of flue gas from coal fired power plants. The main goal is to remove sulfur, particulates, and other chemicals such as mercury from the flue gas prior to environmental release. Governmental regulations by the EPA put limits on the amount of impurities which can be released into the air. The use of mixers to clean and scrub the flue gas is utilized to help power companies meet permitted limits on the release of controlled substances.
The mercury concentration in crude oil and petroleum products can vary in a wide range of less than 0.1 ppb to dozens ppm. Direct mercury determination in crude oil and petroleum products at the range above 5 ppb is covered by ASTM D7622-10(2015) "Standard test method for total mercury in crude oil using combustion and direct cold vapor atomic absorption method with Zeeman background correction". Mercury determination in naphtha and light petroleum products (condensate, gasoline and diesel fuel) at a...
Chemical Oxygen Demand (COD) is one of the most common integral indicators of anthropogenic pollution of water bodies. COD is widely used in the analysis of natural water, to control wastewater treatment from organic various substances.
Besides Mass Spectrometry, a further variety of analysis techniques are categorized as atomic spectroscopy. Analysis techniques which use inductively coupled plasma (ICP), such as ICP-OES and ICP-MS, are among these. With increasing environmental awareness backed by regulations, an increasingly important use of atomic spectroscopy techniques is in mercury analysis. Achieving a high mass flow control performance, e.g. high repeatability or an excellent turn-down ratio, is a prerequisite to achieve a high analyzer...
The natural gas is a significant source of ingres s of mercury in the environment. The typical mercury concentration in natural gas may vary from 0.01 to 200 μ g/m3 . Mercury, being present in hydrocarbon gas, initiates corrosion of pipelines and catalyst poiso ning during gas transportation and processing, and these effects have serious implications for the gas-processing industry.
The main way of mercury removal from human body is it s urinary excretion, which is an important diagnostic medium for screening examination of population, risk group determination, and diagnostics and treatment of mercury poisoning.
Determination of mercury in oil and petroleum hydrocarbon is currently a vital probl em due to the fact that the regulations for the mercury content in emission s from thermal power plants are becoming ever more stringent, and mercury poisons catalysts used in oil re fining.
A conventional standard method of total mercury determination in water using atomic absorption spectrometry (AAS) involves preliminary sample digestion that takes from 30 minutes to 8 hours depending on the digestion conditions.
The use of a mercury analyzer RA-915M/RA-915+ with Zeeman background correction in combination with PYRO-915+ pyrolysis attachment provides direct determination of mercury in process and waste waters contaminated with mercury without digestion or any other sample preparation stages.
