Air Emissions/Off-Gas Treatment

A number of technologies have been widely applied for removal of VOCs from off-gas streams. However, the application of these technologies to off-gases from site remediation may be quite limited. Biofiltration has been widely applied for VOC destruction in Europe and Japan, but it has only recently been used in the United States. Catalytic and thermal oxidation are widely used for the destruction ...

Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...

Case study - Amine tail gas treatment

COVERING YOUR TAIL GAS The discovery of new shale formations throughout the world and the development of new drilling technologies have increased natural gas production and prompted government agencies to instigate tighter air-pollutioncontrol regulations on processing operations. Unfortunately, meeting environmental regulations is not a profit-generating endeavor. Simply put, the time ...

Exhaust gas treatment by an atmospheric pressure microwave plasma

A microwave process for treating exhaust gases from internal combustion engines is presented. The exhaust gases are ionised by microwave energy at 2.45 GHz and the resultant plasma jet discharges into ambient air and exhaust gas environment. A gas analyser was used to measure the change in exhaust gas composition due to the influence of the plasma. Large decreases in CO2, CO and hydrocarbon ...

Greenhouse Gas Inventories and Wastewater Treatment Plants

ABSTRACT A greenhouse gas inventory identifies the sources and quantities of GHG emissions from a facility or a larger organization. Several best practice standards exist that provide guidance for conducting GHG inventories for industrial facilities like a WWTP. Key considerations in a WWTP GHG inventory will include emissions associated with thefacility’s energy use as well as methane ...

Methodology for the assessment of the greenhouse gas impact of wastewater sludge treatment

Nitrous oxide (N2O) and methane (CH4) emissions from the wastewater sector represent the second largest source of greenhouse gas (GHG) emissions of the waste sector. A protocol has been developed to measure GHG from sewage sludge treatment. GHG measurements were performed on two industrial sewage sludge composting plants. Measurement campaigns showed GHG emissions range between 0.18 to 3.40 ...
