METHOD OF SEPARATION OF THE LIQUID COMPONENTS MIXTURE Russian patent published in 2006 - IPC B01D3/00 B01D3/14 

FIELD: chemical industry; petrochemical industry; methods of separation of the mixtures of the liquid components.

SUBSTANCE: the invention is pertaining to the field of chemical and petrochemical industries, in particular, to the method of separation of the mixture of the liquid components and may be used for separation of the components at the rectification installations. The method of separation of the mixture of the liquid components is realized at the installation including the rectifying column supplied with the mass-exchange devices and divided by the dead horizontal partition into two sections: the consolidating section and the exhausting section. The mixture of the liquid components is fed into the exhausting section, the vapors gained in the exhausting section are withdrawn, compressed and fed into the consolidating section; the liquid from the consolidating section through the water seal is fed into the exhausting section of the rectifying column; a part of the vat liquid is withdrawn in the form of the vat product, and the remained part is sent in the main heat-exchanger, where the distillate vapors are coming from the consolidating section of the rectifying column. The part of the formed at that distillate is taken out in the form of the distillate product, and the rest part is fed back in the form of the reflux into the consolidated section of the rectifying column. The vapors formed in the heat-exchanger are sent back into the exhausting section of the rectifying column. The rectifying column has: the connecting pipes for the liquid feeding in and the vapors withdrawal the arranged in the exhausting section; the line of the vapors intake, connected with the compressor linked with the first heat exchanger coupled with the connecting pipe for injection of the compressed vapors into the consolidating section; the connecting pipe for the liquid withdrawal from the consolidating area of the rectifying column connected through the water seal and the second heat-exchanger with the connecting pipe of the liquid injection into the exhausting section; the line of the vat liquid connected to the third main heat-exchanger; the dephlegmator connected to the consolidating section by the line of the vapor withdrawal from the rectifying column. The given invention allows to increase the savings of the heating vapor, to diminish atmospheric emissions and to reduce the amount of the waste waters.

EFFECT: the invention ensures the increased savings of the heating vapor, the reduced atmospheric emissions and the waste waters amount.
