Methods for the control of oil vapour emissions
There are many oil vapours to discharge from oil containers into the atmosphere in oil operations (such as storage and loading). Two basic concepts are discussed regarding the control of oil vapour emission (OVE). The first is to invent active methods to restrain the OVE. The second is to develop passive tail–end remediation technologies to control the released vapour. Oil vapour recovery ...

CH#954 - Diesel/Gasoline Remediation
SITE OWNER: A Truck and Fueling Plaza SITE SURVEY: A tank area that had contained both diesel and gasoline tanks was discovered to have several leaks. The tanks from the pit area were removed. Definition and characterization revealed that not only the tank area was contaminated, but the contaminate plume had migrated under an area where a new building was being constructed. Initial ...

Transforming Environmental Challenges: Innovative Solutions for Crude Oil Contaminated Soil Recycling
In the intricate web of environmental stewardship, the challenge of crude oil-contaminated soil stands as a testament to the pressing need for transformative solutions. In this narrative of remediation, the spotlight gracefully shifts towards cutting-edge technologies, particularly the role of a pyrolysis plant and its specialized counterpart, the oil sludge pyrolysis plant. The Landscape of ...

Stevens enhances groundwater remediation effectiveness - Case Study
The Stevens HydraProbe is now being used to monitor the progress of a new groundwater pollution clean up method called phytoremediation. Phytoremediation is the method by which trees are used to pull contamination out of groundwater. Remediation of contaminated aquifers can take many years to complete. The need for clean, healthy rivers, lakes and streams has stimulated ...

CH#952 - Oil Contaminated Soil
SITE OWNER: A National Overnight Express Package Company SITE SURVEY: Site and geological surveys revealed a contaminated area north of the facility and west of a diesel tank pit. The cause of the contamination was the result of two (2) underground storage tanks (UST™). One tank contained waste oil while the other contained new oil. Both tanks had been removed. A monitor well was ...

Wastewater containing Cr(VI) treatment using solar tubular reactor
The hexavalent chromium, Cr(VI), which is generated in the electroplating process, is toxic to most organisms and potentially harmful to human health. The method generally used for remediation of wastewater containing Cr(VI) employs chemicals with high toxicity. This work proposes an alternative technology for the treatment of these wastewaters, based on photochemical reduction of Cr(VI) by ...

In situ Chemical Oxidation: An Innovative Groundwater Remediation Technology
A promising new technology, in situ Chemical Oxidation (ISCO), has the potential to supplant the more widely used pump-and-treat groundwater remediation technology by destroying groundwater contamination in situ (in place). ISCO is the process of oxidizing contaminants in the groundwater and soil by injecting water containing high concentrations of an oxidant to the site of the contamination. ...
