Abstract
- In this study, we evaluated the applicability of the dimethyl ether (DME) dewatering method originally developed for high-moisture coal to superabsorbent polymer (SAP) and disposable diapers. It was found that liquefied DME successfully extracts water from SAP and disposable diapers. However, the polypropylene outer film and polyurethane used in diapers tended to dissolve in the liquefied DME and were subsequently released with the water discharged. These compounds are highly viscous, making it difficult to remove them from the drain outlet of the prototype. Therefore, the mechanics of the drain outlet should be considered in future studies.
