Sustainable soil remediation by refrigerated condensation at sites with `high-concentration` recalcitrant compounds and NAPL: two case studies

Remediation of recalcitrant compounds at sites with high concentrations of volatile organic com- pounds (VOCs) or nonaqueous-phase liquids (NAPLs) can present significant technical and financial (long-term) risk for stakeholders. Until recently, however, sustainability has not been included as a significant factor to be considered in the feasibility and risk evaluation for remediation ...

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 ...

Simultaneous removal of parathion and methyl parathion by genetically engineered Escherichia coli in a biofilter treating polluted air

A biofilter inoculated with a genetically engineered Escherichia coli strain was successfully applied to treat air streams containing a mixture of parathion and methyl parathion (MP). Average removal efficiencies of 95.2% for parathion and 98.6% for MP were obtained during the overall operation period. Compared with conventional biofilters, the biofilter inoculated with the engineered E. coli ...

Flue Gas Treatment/ Power Plant - Case Study

A power plant is using a wet scrubber system to treat flue gases. Sofi Filter treats the flue gas condensate coming from sand filter overflow before the liquid enters reverse osmosis system.Reverse osmosis is sensitive to even the finest solids, and the solids concentration limits, in this case particularly the aluminum and iron particles, have been set very low. Current maximum acceptedlevel is ...

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 ...

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 and money ...

U.S. Air Force DOD Project - Case Study

Environmental Issues Controlling the off-gas from a remediation project, where high concentrations of petroleum hydrocarbons are present, can be a difficult if not dangerous process when utilizing internal combustion engines and conventional oxidation technology. In more recent years, the use of high vacuum pumps to accomplish both liquid and gas phase extraction — sometimes referred to ...

Data Requirements Air Emissions/Off-Gases

Predictive modeling may be usefelected to represent the system (e.g., SVE treatment, incinerator, etc.), and site and contaminant informaul in estimating emissions from a site or treatment system. An appropriate theoretical model is stion is used to estimate gross emissions. Because many variables affect emission rates, this approach is limited by the representativeness of the model and by the ...

Decolourisation of dye solution using an electrical discharge with TiO2 suspension

An electrical discharge in water with TiO2 suspension has been applied for the decolourisation of methyl orange as a model of dye. The results showed the decolourisation was successful in the reactor. The increase in the flow rate of gas injection enhanced the decolourisation rate. Oxygen injection had a stronger influence when compared with Ar injection. The suspension of TiO2 improved the ...

The Influence of PVC on the Quantity and Hazardousness of Flue Gas Cleaning Residues from Incineration

The study estimates the influence of PVC on the quantity and hazardousness of flue gas residues from incineration. The analysis has been carried out on both theoretical and practical terms. A distinction between dry, semi-dry and wet gas treatment systems has been made. The influence of PVC has been assessed on the combustion steps and therefore on the distribution of chlorine and other ...
