AIChE Journal, 1999
AbstractOne of the environmental challenges faced by the pharmaceutical and specialty chemical industries is the widespread use of organic solvents. With a solvent‐based chemistry, the solvent necessarily has to be separated from the product. Chemical species in waste‐solvent streams typically form multicomponent azeotropic mixtures, and this often ...

In Situ Solvent Recovery by Organic Solvent Nanofiltration
ACS Sustainable Chemistry & Engineering, 2014Reducing solvent consumption in the chemical industries is increasingly becoming a topic of interest. The field of organic solvent nanofiltration (OSN) has markedly evolved in the past decade, and effective membranes are now available that can withstand aggressive solvents while completely rejecting small solutes at the lower end of the nanofiltration ...

Journal of the American Oil Chemists' Society, 1983
AbstractA brief overview is presented of the economic significance of solvent recovery in the oilseed extraction industry in view of the steep price advance of hexane since 1974. The present solvent recovery practices in oilseed plants are outlined with addition of operating techniques since 1976.

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

Distillation and solvent recovery
Journal of the American Oil Chemists' Society, 1974AbstractThe historical development of various miscella distillation systems used in solvent extraction of oil‐seeds is reviewed, and their economics are compared. In addition, the design of solvent recovery systems and their economic justification are reviewed.

Solvent Recovery via Organic Solvent Pressure Assisted Osmosis
Industrial & Engineering Chemistry Research, 2019The organic solvent forward osmosis (OSFO) process suffers from certain drawbacks, such as relatively low solvent flux. One strategy to overcome the relatively low solvent flux of OSFO is to utilize an external hydraulic pressure, on top of the osmotic pressure difference across a membrane, to enhance the solvent transport through the membrane.

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 ...
