OIL DISTILLATION METHOD Russian patent published in 2009 - IPC C10G7/06 

FIELD: oil-and-gas production.

SUBSTANCE: invention related to oil-and-gas production and can be used at ADU/VDU. Invention related to oil distillation method, includes dissolved hydrocarbons, according which oil heated in a heat exchanger drains to K-1 column for degassing and partial stripping, the rest of K-1 column after heating up in a kiln drains into K-2 column for separation of a gasoline, kerosene and summer diesel fuel and masut, which after heating up in the kiln to be forwarded to vacuum column for subdivision on vacuum diesel fuel, vacuum distillate and goudron, but unstable distillate from K-1 column with totally absorbed dissolved hydrocarbon gases to be forwarded to stabilising column for subdivision of dry gas, reflux and stable distillate, decrease reflux in to K-1 column and provide almost total absorption of dissolve hydrocarbon gases, and forward the stable distillate from K-1 column under its own pressure to column K-2 as a partly evaporated reflux.

EFFECT: maximal distillation of a high quality products and decrease of the equipment loads.
