The determination of Total Petroleum
Hydrocarbons (TPH), greases, and lubricant
residues are important environmental and
industrial tests. Fuel and lube oils can be
determined in water and soils to track spills and
storage tank leaks, while many military and
industrial situations require certain components
(gas regulators, space shuttle components,
weaponry parts, etc.) to have a maximum limit
of grease or oil on them to prevent potentially
These tests are currently done by extracting and washing, respectively, the materials being tested with Freon-113 (Dupont), or equivalent non-hydrocarbon solvent. The extract/wash liquid is placed in a cell and measured in a filter infra-red photometer optimized for ~2940 cm-1 (or ~3.4 microns). Regular Freon Chloro- Fluoro-Carbons have no absorbing bands here, so any signal has to come from the hydrocarbons that are extracted into the Freon.

Ivey-Sol Technology has potential to increase oil recovery of oil-sands waste by 15-25 percent
Alberta’s oil sands are comprised of one of the world`s largest sources of bitumen, containing an estimated 1.6 trillion barrels. About two tonnes of oil sands must be dug up and processed to produce one barrel of oil. Oil sands recovery processes include extraction and separation systems to remove bitumen from sand and water. Separating the oil from the sand is difficult and costly, and getting the most petroleum at the least cost is a key challenge. Once the petroleum is recovered from the oil sands, a sand...

Prevention of Oil Spill Pollution in Seawater Using Locally Available Materials
Abstract Oil spill pollution a severe environmental problem, which persists in marine environment or in inland water across the world, has grown to an alarming magnitude with increased levels of oil production and transport. Causes of it is either accidental or due to operation wherever oil is produced, transported, stored and used on sea or land. Hence, it is almost impossible for marine life to be free from the danger of an oil spill, though the discharge of oil is controlled by international convention. Prime...

Failure of Magnesium Peroxide to Remediate Petroleum Hydrocarbon-Contaminated Sites (PDF)
Researchers promote magnesium peroxide as a viable method to aerobically bioremediate petroleum hydrocarbons and restore groundwater quality. Suppliers claim that dissolved oxygen released in the saturated zone promotes biological growth for degrading a wide range of hydrocarbons dissolved in water and sorbed onto soil particles. Yet, staff with the CaliforniaRegional Water Quality Control Board, Lahontan Region (Regional Board) found that magnesium peroxide failed to achieve target BTEX and total petroleum...
Water Industry on the Eco Wave?
A wave of privatization is rolling through the water industry – at the environment‘s expense? In order to provide an answer to this question, the Environmental-Rating agency oekom research AG, Munich, put a number of water supply companies and manufacturers of water appliances to the environmental test. In results published today, oekom identifies the British water supplier Severn Trent as the environmental leader of the water supply group with a B grade in the overall Environmental-Rating. The Austrian water...
Bioremediation of an Oil Spill
Bioremediation is the method of choice to effectively clean up a small spill of hydrocarbons. In this case, five-hundred liters of BTEX has spilled from an above ground storage tank into a pasture that is located at the west edge of the Royal Roads University (RRU) grounds. The soil is classified as a Gleyed Eutric Brunisol based on recent laboratory analysis; it contains clay, but is fairly loose and porous for the upper meter, and then reaches an impermeable clay boundary (Burke, 1998). The dominant vegetation...

Properties and Behavior of Inorganics in Contaminated Soil
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...
