Carbon Capture and Storage (CCS) is an emerging method of reducing greenhouse gas (GHG) emissions of power plants. In a process called ‘scrubbing’, the carbon dioxide emissions can be absorbed into chemical solvents consisting of amines or carbonates. Scrubbing is a well-established method of carbon capture, with virtually every commercial CO2 capture plant in operation using this process. In the process, the first step is the removal of impurities from the flue gas, such as hydrocarbons and oxides of...
Several EU directives and national laws in European countries set requirements for continuous monitoring of flue gas emissions at power plants. Further requirements are set on the quality assurance of the installed measurement systems at the plants. The relevant standard in this regard is EN 14181:2004, the quality assurance of automated measuring systems. The standard dictates how to determine that the measurement systems installed for continuous emissions monitoring at a plant operate according to the directives...
In most combustion process atmospheric nitrogen reacts with oxygen in high temperature conditions to produce nitrogen oxides (NOx). Total NOx production is the sum of nitrogen monoxide NO and nitrogen dioxide NO2. The emissions of these gases are controlled through setting of emission limit values (ELVs) for power plants.
Nitric acid HNO3 is an important intermediate reagent for production of several important end products, such as fertilizers, explosives, dyestuffs/pigments, pesticides, pharmaceuticals, photographic materials, plastics, and synthetic fibers. At nitric acid manufacturing plants, the Gasmet™ FTIR Gas Analyzer can be used to measure several gaseous components from the process stream for purposes of process control. A single system can be used to measure the high levels of nitrogen monoxide NO and nitrogen...
Cold Lime Softening: Hard water is water that has high mineral content. The name comes from the hard scale that forms when this water is boiled. It is not harmful to human health, but in the industrial setting it causes costly breakdowns in boilers, cooling towers, and other water handling equipment. The divalent cations Mg and Ca are the most frequently found minerals causing hard water. These ions enter water supplies by leaching from minerals in underground aquifers.
Process control and emissions monitoring in a brick plant is a challenge due to the high concentrations of HF. The HF is generated in the process and gas phase HF can reach 50 mg/m3 or more. To use an extractive system in this environment will demand a lot of maintanence.
The consumption of scrubbing material in a scrubber is related to the mass flow of acid gases. Hydrogen chloride (HCl) and sulphur dioxide (SO2) are the major acid gases in an incinerator. By measuring the mass flow of SO2 and HCl in the raw gas going into the scrubber, it is possible to calculate the required quantity of scrubbing material.
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.
When in businesses such as building construction, agriculture, concrete and asphalt, mining, sandblasting, and smokestacks, fugitive dust can be prevalent. While low levels are unavoidable, many states have regulations concerning the volume of particulate matter an individual business may emit into the ambient air.
Heat stress is a major problem when it comes to manual labor, and worker safety should be a top priority of every business. Because of this, environmental monitoring is crucial. When running a business, you already have plenty of things to worry about without dealing with the incorrect information given by regional forecasts. We’re here to offer a better alternative. With a weather station configured to your specific needs, you can rest easy knowing that the information you’re receiving is current,...
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.
It is widely understood that manmade CO2 emissions are a major contributor to climate change. As one of the most prevalent greenhouse gases emitted from industry, methods to reduce CO2 are both a political and industrial hot topic. Research continues on ways to harness or reduce CO2 emissions from a variety of sources.
FGD is Key to Coal-Fired Power Generation: Wet Flue Gas Desulfurization (FGD) is a process by which coal-fired power plants remove sulphur dioxide (SO2) before emitting their flue gas into the atmosphere. The water intensive scrubbing process requires a durable treatment technology as FGD blowdown wastewaters are highly contaminanted.
Current Total VOC MeasurementsThe most common, and current standard, method for measuring Total Volatile Organic Compounds (VOC) is the use of a Flamed Ionisation Detector (FID). This gives a representative value of the total carbon content of a gas stream, as the FID cannot tell which specific organic compounds are present.
A college operates four chillers with a cooling capacity of 1,600 tons. The cooling water system includes four individual cooling towers with a total water volume of 14,000 gallons. Scale and deposits became a serious issue under chemical treatment, and local effluent discharge regulations were requiring the water treatment system to be environmentally friendly.
Through long-term partnerships with producers of cooling equipment, we have been able to establish ourselves as a reliable supplier of customised appliances for refrigeration industries. All appliances can also be supplied with internal coatings (cold coating and stove enamelled coatings).
