A method and apparatus for the in situ purification of aquifers contaminated with ethers and/or alcohols using a bacterial culture, a method of delivering the culture to the subsurface, and an oxygen delivery system.

In situ method and apparatus for biodegradation of alkyl ethers and tertiary butyl alcohol

A process and apparatus for the in-situ bioremediation of aquifers contaminated with chemicals by delivering a chemical degrading bacterial culture using a bacterial slurry delivery apparatus, which is designed to prevent backflow of soil and clogging of the apparatus, and a networked oxygen delivery system.

In-situ bioremediation process and apparatus

Situ method and apparatus for biodegradation of alkyl ethers and tertiary butyl alcohol

A process is provided comprising the steps of contacting a Group VIII metal hydrogenation catalyst residue containing polymer solution with from about 2 to about 50 parts by weight water based on 100 parts by weight of polymer solution, centrifuging the polymer from metal containing particles with a centrifugal force such that the centrifugal force times the time duration of centrifugation divided by the viscosity of the polymer solution equals or exceeds about 50 G-minutes/cp, and recovering a polymer solution comprising less than 10 ppm by weight, based on the polymer, of the Group VIII metal.

Removal of nickel catalyst from polymer solutions by water addition and

Treatment of diesel or jet fuel with a non-ionic, macroreticular, cross-linked, acrylic aliphatic ester resin reduces polar impurities and (diesel) color.

Removal of polar impurities from diesel and jet fuel

A process is disclosed for reducing the level of corrosive impurities in sulfolane solution originating from a process for the extraction of aromatic hydrocarbons from petroleum and having a pH of at least 8.5, comprises combining a sulfolane-soluble polyprotic acidic substance with said sulfolane to form a solid phase containing at least a portion of said corrosive impurities, and separating the sulfolane from the solid phase.

Process for reducing corrosive impurities in sulfolane used for

The level of impurities such as glycerol-based acetals and/or ketals in glycerine, particularly glycerol-dimethylketal, is reduced by extraction of the glycerine with supercritical or near critical carbon dioxide.

Glycerine purification process

The drying of moist CO.sub.2 at conditions above or near the critical point of CO.sub.2 is improved by contacting the CO.sub.2 with an electrolyte desiccant adsorbed on a permeable solid desiccant.

Combined desiccation of substantially supercritical CO.sub.2

In drying supercritical or nearcritical CO.sub.2 for use at supercritical conditions, the loss of desiccant, contamination of product, compressor horsepower requirements, and heat requirements can be substantially minimized by using glycerol as the desiccant.
