Recovery of nitrotoluenes in wastewater by solvent extraction
Journal of Hazardous Materials, 2007Toluene extraction was utilized to recover 2,4-dinitrotoluene (DNT), 2,6-DNT, and 2,4,6-trinitrotoluene (TNT) from wastewater of toluene nitration process. The batch-wise experiments were performed to elucidate the influence of various operating variables on the extracting behavior, including extracting temperature, volume ratios of solvent versus ...

Journal of Membrane Science, 1988
Abstract In industrial processes such as drying, glueing, and coating, huge air streams become loaded with solvents. For economical and environmental reasons these solvents should be reused. Composite membranes produced in hollow fiber form using polydimethylsiloxane as the selective barrier are tested to recover these solvents. A hollow fiber module

The Solvent Requirements for Vapex Recovery
SPE International Heavy Oil Symposium, 1995Abstract In both SAGD and VAPEX, recovery agents are introduced into the reservoir and these displace oil to horizontal wells located at the base. In each process it is desirable to inject at a pressure equal to or slightly below the pressure of the surrounding reservoir, so as to prevent flow of fluids to outside the recovery pattern.

Co-solvent selection and recovery
Advances in Environmental Research, 2004Abstract The selection and recovery of two or more solvents (i.e. co-solvents) are studied because of their importance in environmentally responsible processing. A particularly challenging problem arises when the contaminants (or solutes) are comprised of a mixture of volatile and nonvolatile compounds. The nonvolatile components present difficulties

Corrosion of Solvent Recovery Towers
British Corrosion Journal, 1975Abstract Mild steel solvent recovery towers packed with charcoal sometimes show exceptionally high rates of corrosion of areas of steel in physical contact with the charcoal. The corrosion may be increased in the presence of chlorinated solvents. The attack results from galvanic interaction between charcoal and steel, the function of the chlorinated ...

A System for the Recovery of Solvent Vapors
Journal of the SMPTE, 1963A system has been designed to recover exhausted film-cleaning solvent vapors, and to treat the reclaimed solvents in such a way as to render them completely reusable in the film cleaning machines from which they were generated. Installation and operation of the system are described.
