Treatment, of petroleum, residua, heavy oil, or bitumen with a low-boiling liquid hydrocarbon results in the separation of brown to black powdery materials known as asphaltenes (Figure 1-12). The reagents for effecting this separation are n-pentane and n-heptane, although other low molecular weight liquid hydrocarbons have been used (van Nes and van Westen, 1951; Mitchell and Speight, 1973).

During the ,drilling, process, a large volume of ,cuttings, are generated and carried out of the well by the ,drilling fluid,. These ,cuttings, must be separated from the mud liquid so the liquid can be reinjected into the drill string to remove more ,cuttings,. ,Cuttings, contaminated with ,drilling, mud are a major source of petroleum industry waste.

This invention involves the separation of clay-contaminated bitumen from sand with a solvent. The bitumen is dissolved with an organic solvent such as condensate from a natural gas well. The clay is separated from the dissolved bitumen and the solvent is recoverd and recycled. The sand is washed with water containing a carefully selected, nonanionic surface active agent to remove residual ...

The ,price, of soybean has not changed between 1981 and 2005; US$223 and US$208/t in 1981 and 2005, respectively. As a consequence of ,price, stagnation, the total cost of producing a hectare of soybean for American farmers in 2005 was US$663 against the gross value of US$654/ha of the harvest (SoyStats, 2007). The situation is the same worldwide.

Historically, the prime factor inhibiting the use of this solvent replacement has been the low solubility of most materials in CO2, in both its liquid and ,supercritical, states. With the discovery of CO2 surfactant systems, Professor Joseph M. DeSimone and his students have dramatically advanced the solubility performance characteristics of CO2 systems for several industries.
