Content is less than 2%, and condensation point and cloud point are respectively lower than -9 DEG C and -13 DEG C.
2nd, in the present invention, the croude fatty acids solution after emulsification separated using butterfly centrifugal seperator, and the equipment is most
Big feature is disposably to separate the sour clear liquid of crude oil, emulsified solid and the water in emulsion, and separating effect is preferable, and whole
Individual charging is continuation mode with discharging process, and the technical process has certain automated control technology, and production efficiency is high, reduces
The workman amount of labour, reduces labor intensity.
3rd, in the present invention, the emulsifying agent and water isolated can be recycled, so not only energy-conserving and environment-protective, and economy
Preferably.
4th, in the present invention, the saturated fatty acid purity that the emulsified solid isolated is obtained after demulsification is of a relatively high, can
For making other Related products of soap or our company.
5th, preparation technology of the present invention, is produced without waste gas, waste water and waste residue, with simple to operate, technique in process of production
Flow is short, energy-conserving and environment-protective the features such as.
