5.2 Demulsifier "Hercules 1603"
The role of the demulsifier in the oil desalting process is the destruction of formation water globules protective shells and preventing their formation around the globules supplied to the EDP (Electrical Desalting, Dehydrating Plant) fresh wash water.
Over the past three years, specialists of RPC "Macromer", JSC "VNIINP" and NIF "Engineer Service VNIINP" have develop oil soluble demulsifier specifically designed for the destruction of oil-water emulsions with a deep oil dehydration and desalting on EDP. Table 22 shows typical test results of demulsifiers samples.

Efficiency of the oil preparation was provided as in each stage and in the installation as a whole, and with a relatively small flow rate of washing water (1,9 • 3,6% of oil in each stage, or a total on installation of 4,5-6,4% in oil).
With the increase of water supply was observed deepening of oil desalting. Degree of oil desalting insignificantly depended on the demulsifier flow rate. By increasing of demulsifier flow rate from 2.3 to 3.9 g / t (about 1.7 times), they increased by only 2%, which indicates sufficient flow of demulsifier at the existing water flow.
Discharged water has a relatively low content of residual oil, which is largely depends on demulsifier flow rate: it reduction led to the growth of the oil content in the drainage water. The demulsifier almost no goes into the aqueous phase, as evidenced by the low surfactant content in the drainage water
