Title:
APPARATUS AND METHOD FOR SEPARATING WATER AND OIL IN AQUEOUS WASTE LUBRICANT
Document Type and Number:
WIPO Patent Application WO/2014/038797
Kind Code:
A1
Abstract:
An apparatus and method for separating water and oil in an aqueous waste lubricant are disclosed. Inflowing aqueous waste lubricant from the exterior is stored in a storage bath, and the stored aqueous waste lubricant is moved to a reaction bath. An acid is added to the aqueous waste lubricant moved into the reaction bath and stirred at a certain rate in order to coagulate the oil in the aqueous waste lubricant. The coagulated oil is moved to a separation bath and left standing in order to separate the water and oil. The water separated into the lower layer in the separation bath is moved to a chemical reaction bath, and the oil separated into the upper layer is moved to the storage bath for storage. An alkaline compound is added to the water moved to the chemical reaction bath to control acidity, and stirring is conducted to produce purified water. At room temperature, the water and oil in a non-degradable aqueous waste lubricant may be separated through simple cracking and coagulation reactions. Thus, total normal hexane extracting material (n-H) may be simply and efficiently separated and removed.
