Abstract: A non-destructive method uses ultrasound measurements to determine some mechanical properties of an elastomeric material. The measurements can be made during manufacture of the elastomer for quality control purposes. The measurements can also be made on the elastomeric material in situ as part of a device to assess degradation of the elastomer over time.

Abstract: A system and process for removing divalent cations from a rich MEG feed stream is presented. An ion exchange bed containing a cation exchange resin adsorbs the divalent cations in the rich MEG feed stream as it flows through the ion exchange bed. After the divalent ions have been removed, the feed stream flows through a flash separator and a distillation column to reclaim MEG. Alternatively, the feed stream flows through a distillation column to regenerate MEG. The spent cation exchange resin may be regenerated in place using a regeneration brine comprised of sodium chloride and water. After use, the regeneration brine may be disposed as waste or recycled to the brine storage tank and re-used to regenerate the cation exchange resin.
