Accessing critical resources such as geothermal energy and natural gas requires drilling — an expensive, energy-intensive, messy process with today`s technology. An MIT team has been looking into a more elegant approach. Instead of grinding rock to bits, they would use a continuous beam of energy to vaporize it and then blow out the tiny particles that form with a high-pressure stream of injected gas. Using a novel experimental setup and a device used in fusion experiments, the researchers have now vaporized...

About Hydraulic Fracturing
Hydraulic fracturing, commonly referred to as fracing, is a proven technological advancement which allows natural gas producers to safely recover natural gas from deep shale formations. This discovery has the potential to not only dramatically reduce our reliance on foreign fuel imports, but also to significantly reduce our national carbon dioxide (CO2) emissions and accelerate our transition to a carbon-light environment. Simply put, deep shale gas formation development is critical to...
Bentonite is a naturally-occurring clay material, largely composed of the mineral, sodium mont-morillonite. The dominant property of bentonite is that it swells to many times its dry volume when hydrated by water, forming a viscous fluid with high gel strength. This makes bentonite an excellent product when used as a sealant, for preventing the influx of surface water into a well, sealing abandoned wells, or building slurry walls to contain contaminated groundwater.Bentonite is also frequently used as the base...
A rig worker smells rotten eggs near the well head, rubs his itchy eyes as he investigates the frosty pipe connections. After a few moments, he believes all is fine as he no longer smells the tell-tale hydrogen sulphide odour. In this scenario, we can only hope the worker recognises the danger and quickly leaves the site. Oil fields, especially mature ones, can produce hydrogen sulphide gas – deadly at relatively low concentrations. On average, a person takes 12 breaths per minute, so if a hydrogen sulphide...

[Master`s Thesis in Environmental Engineering] As an alternative technology for use of local governments, we propose to demonstrate the suitability of anaerobic digestion (AD) system to treat the organic fractions of municipal solid waste (OFMSW). To enhance the process, we applied several pre-treatment steps: comminution, extraction, and addition of sodium hydroxide to achieve the desired pH 8.0. The pre-treated kitchen waste slurry was continuously pumped to an upflow anaerobic sludge blanket reactor (UASB)...
As the world searches for fuel alternatives to gasoline, a clear candidate to lead the way has emerged, Ethanol. Ethanol production for use as a fuel additive (or to be used directly as a fuel source) has grown in popularity due to governmental regulations and in some cases economic incentives. Both regulations and incentives seem to be based on environmental concerns as well as a desire to reduce the oil dependency of our industries and our everyday lives.
The Warrenton (Ore.) Wastewater Treatment Plant is brand new. In fact, it initiated full operation Jan. 2, although the plant has been utilized since June 28, 2006.
The sequencing batch reactor (SBR) plant was constructed on top of an existing facultative sewer lagoon site. The site conditions prohibited deep excavations, so the three basins for the SBRs are shallow, at only 12.5 ft (3.8 m), with a top operating water level of 8 ft to 10.5 ft (2.4 m to 3.2 m). The basins are 94 ft × 120 ft (29 m × 37 m) and have...
Abstract
Although different barium compounds are known to exhibit vastly different toxicities, cleanup standards for barium in soil or sediment at environmental corrective action sites are typically based on total barium concentration without regard for the specific barium compounds present. However, the Texas Commission on Environmental Quality (TCEQ) has recently agreed that the insoluble barium compound barium sulfate (i.e., barite) is not a compound of concern with regard to human health, thereby eliminating...

The Sydney Tar Ponds of Nova Scotia are the result of a century of coal mining and steelmaking, which left behind 900,000 tonnes of chemical waste. About 5 per cent or 45,000 tonnes of this waste is contaminated with high levels of PCBs. Two years ago a federal-provincial plan was announced to clean up the Tar Ponds over 10 years at a cost of $400 million, and this led to the creation of the Sydney Tar Ponds Agency.
So where am I going with this? Well, the agency proposed that incineration techniques be used...

Pollution Prevention Guidelines to provide technical advice and guidance to staff and consultants involved in pollution-related projects. The guidelines represent state-of-the-art thinking on how to reduce pollution emissions from the production process. In many cases, the guidelines provide numerical targets for reducing pollution, as well as maximum emissions levels that are normally achievable through a combination of cleaner production and end-of-pipe treatment. The guidelines are designed to...
Cavitation is a major problem in the chemical industry because it affects a basic tool, the centrifugal pump. A sudden increase in the velocity of the pumped liquid reduces the inlet pressure, sometimes below the vapor pressure.The result is formation of gas and bubbles.
Detecting the signs of cavitation, and correctly identifying and understanding the type of cavitation present, can help an operator prevent serious damage.
HOW CAVITATION OCCURS
The pressure of the liquid in a centrifugal pump drops as it...
Often, specific technologies may be ruled out, or the list of potential technologies may be immediately narrowed, on the basis of the presence or absence of one or more of the chemical groups. The relative amounts of each may tend to favor certain technologies. Metals may be found in the elemental form, but more often they are found as salts mixed in the soil. At the present time, treatment options for radioactive materials are limited to volume reduction/concentration and immobilization. Asbestos fibers require...
Introduction
Solidification/stabilization (S/S) reduces the mobility of hazardous substances and contaminants in the environment through both physical and chemical means. Unlike other remedial technologies, S/S seeks to trap or immobilize contaminants within their `host` medium (i.e., the soil, sand, and/or building materials that contain them), instead of removing them through chemical or physical treatment. Leachability testing is typically performed to measure the immobilization of contaminants. S/S techniques...
