Beschreibung
Zusammenfassung:	A low-temperature demulsifying agent for dewatering paraffin-base crude consists of AE8051 15-20 wt%, SAA 20-30 wt%, BP28 10-18 wt%, FC-NO1 surface activator 0.05-0.1 wt%, methanol 20-30 wt% and water residues. The crude dewatering temperature is between 35-40 deg. C, use level is at a range of 50-80mg/l, water content is less than 0.2% and oily content of sewage is less than 500mg/l. It accords with crude output standard.
