Title:
METHOD FOR PETROL DISTILLATION
Document Type and Number:
WIPO Patent Application WO/2001/090276
Kind Code:
A1
Abstract:
The inventive method for petrol distillation consists in supplying petrol to a distillation column, in separating the petrol into hydrocarbon fractions therein, evacuating liquid fractions from the column and evacuating the vapor of light hydrocarbons fractions from the top of said. Before heating, petrol is supplied to a liquid-gas jet device with the aid of a pump, whereby hydrocarbon gases invading the jet device through a gas entry connected to a pipe-line for a low-pressure gas are pumped out. The low pressure gas is compressed in the jet device and a part of the hydrocarbon gas contained in the low-pressure gas is absorbed by petrol, in addition to forming a gas-liquid mixture in the jet device. The gas-liquid mixture is supplied to a separator where the compressed gas is separated from petrol and the hydrocarbons are absorbed thereby. The compressed gas is delivered from the separator to a customer. The petrol and the absorbed hydrocarbons are heated and re-supplied to the distillation column.
