Membrane petroleum residues

Direct deasphalting of petroleum residues. Ultrafiltration zirconia membranes with a pore diameter of 6.3 nm on carbon support have been used to remove asphaltenes from a long residue at a temperature of 150X [Guizard et al., 1994]. With a higher than normal...

The SBP slurry-phase bioremediation system can treat a wide range of organic contamination, especially wood-preserving wastes and solvents. A modified version can also treat polynuclear aromatic hydrocarbons (PAHs) such as creosote and coal tar pentachlorophenol (PCP) total petroleum hydrocarbons (TPH) and chlorinated aliphatics, such as trichloroethene (TCE). The technology can be combined with SBP s membrane filtration system to form a soil cleaning system to handle residuals and contaminated liquids.
