Article Preview

In order to reduce the temperature of paraffin-based crude oil,is applied low-temperature dehydration performance of the AE8051, is the good effects of high viscosity crude oil dehydration polyether polyol-based SAA and polyoxyethylene polyoxypropylene glycol ether BP28 for "coordination" recovery distribution is also applied. As result , a small amount of C-F surfactant will make the system active and increase the solubility of paraffin-based demulsifier in crude oil at low temperature FYR-015. The basic formula, which by low-temperature synthesis of a series of demulsifier samples at concentration of 200mg / L(in water) and 30% of the joint stand of the mixed oil at 40 °C, has been the relative dehydration rates of 90 minutes over 93% of the 3 a formula of low-temperature demulsifier, the dual temperature demulsifier compound obtained in the same temperature, the same dosage effect of the case of dehydration and a single dose equivalent in dosage trials are three formulations of low temperature demulsifier in 40 °C are the best dosage 100mg / L. Xuanze solid content of 55% of finished emulsion breaker formulation 5 into field use, dosage to 60 mg / L when the water content of crude oil were isolated less than 0.2%, to reach the standard of foreign crude oil output quality, extrusion sewage oil is less than 50 mg / L, water clear.
