Solvent sublation for waste minimization in a process water stream - a pilot-scale study

摘要

Solvent sublation, an adsorptive bubble separation process, was carried out on a pilot scale to separate dilute concentrations (30-100 ppmw) of naphthalene from a process water stream at a temperature of 140deg.CF. The test was conducted at the Borden Chemicals and Plastics (BCP) acetylene plant site located in Geismar. Louisiana. A carbon steel column of 6'' i.d. and 17 high was constructed. White mineral oil supplied by Texaco Inc., was used as the organic solvent for solvent sublation.
