METHOD OF RECYCLING CHEMICAL

摘要

In order to recycle a chemical, a chemical that is recovered from a predetermined chemical process and includes a foreign substance is reacted with a supercritical fluid to educe the foreign substance. Then, the educed foreign substance is separated from the chemical and the supercritical fluid. Thereafter, the supercritical fluid is separated from the chemical to recover the chemical. A foreign substance included in chemical used in a predetermined process may be easily removed and recycled, thereby reducing amount of a waste chemical to prevent environmental pollution, and reducing cost for disposing waste chemical.
