Thermal Activation of Digested Sewage Sludges for Carbon Dioxide Removal from Biogas
Sewage sludges from a wastewater treatment plant (WWT) were anaerobically digested for the biogas production and energy use. The refuses of such process were used as starting material for the char production for the gas cleaning process. These char samples were experimentally tested as adsorbents for the removal of CO2 and trace contaminants from the biogas mixture produced from the WWT plant. A ...

Gas Concentration Monitoring in the Industry
There are often rules and regulations dictating what and how to monitor when it comes to emissions to the ambient air. By example, the European Union has established the Industrial Emissions Directive (the IED, 2010/75/EU) with conclusions on best available techniques (BATCs) for different types of industries.These documents serve as guidance and in some cases minimum requirements for national ...

Pollutants in Emissions to Air – What’s in the Smoke?
Speaking of industrial emissions to air, it is often a matter of emissions resulting from combustion processes. The main components of the emissions are nitrogen and some excess oxygen originating from the incoming air being fed to the combustion process, as well as water and carbon dioxide (CO2) being the primary results of the combustion reactions. The concentrations are at percentage levels. ...

Continuous Emissions Monitoring – What, Why, and How?
In an ideal world, combustion merely gives emissions of water and carbon dioxide (CO2). Water is a non-issue while CO2 nowadays is looked upon with concern, giving its key role in the global climate changes. However, the issues with emissions do not stop there.The thermal processes also generate nitrogen oxides, primarily NO. Depending on the fuel composition, the type of combustion process, and ...

The advantages of Qingdao Newtep dry ice cleaning machine over other cleaning methods
The advantages of Qingdao Newtep dry ice cleaning machine over other cleaning methods: Cost savings CO2 is a component of the atmosphere, easy to access, and affordable. The only power-consuming equipment is air compressors. Dry ice is directly volatilized into CO2 gas during the cleaning process, which can save the cost of cleaning the cleaning medium. Dry cleaning process Dry ice cleaning is ...

Mercury emissions of the German cement industry - Case Study
In December 2019 the new BREF (Best Available Technology Reference) document for waste incineration was published in the EU. One important topic in the Best Available Technology (BAT) conclusions is the request for continuous monitoring of mercury (Hg) emissions. In the BAT conclusions are mentioned so-called BAT-Annual Emission Levels (AELs) for daily averages, with Hg concentrations in the ...

Mercury: measure and control
Following the new EU BREF document for waste incineration, European cement plants have to implement the requirement to continuously monitor and abate mercury emissions. To enable this they will need to apply technologies that measure mercury in the raw gas and optimise sorbent use. In December 2019 the new BREF (Best Available Technology Reference) document for waste incineration was published ...

Pollutant reduction control and Continuous Emissions Monitoring at Waste-to-Energy Plants
Waste is generally undesired, and best not generated at all. The second best alternative to manage waste is to recycle it. However, there is also waste that for various reasons is not recycled. Landfills have then been the old-school solution, but it is for environmental reasons becoming a less viable option. What then remains is waste incineration, in most cases while recovering the energy ...

Benefits of Hot Water Pressure Washers for Wet Steam Cleaning
Hot pressure washers have revolutionized commercial cleaning processes. Roads, gas stations, boats, cars, airplanes, factory floors, basements, kitchens and similar areas can now be cleaned more easily than before. No longer are contractors depending exclusively on tedious methods such as trailers with rotary brushes to handle layers of grease and grime. Hot water pressure washers hold many ...
