Description

one

The invention relates to devices for isolating a desired product in the selection of garob and can be used in the refining and petrochemical industries.

The sample preparation device is intended for settling, filtration and thermal decomposition of the complex formed in the technological process.

Isolation of the target product during its continuous production is necessary to ensure prompt and reliable control of the quality of the product at the main stages of its production.

A sample preparation device for isolating a target product from multicomponent liquid mixtures of hydrocarbons is known, consisting of a settling tank, a regenerator, a phase separation column and a filter equipped with a thermostatic system and shut-off and control valves.

However, the sample preparation process takes a long time, which is determined by the need for successive sedimentation, filtration, and separation of the sample in the phase separation column. Moreover, it is impossible to combine the processes of settling solids and separating low-boiling components.

In order to intensify the process and reduce the lag time in the proposed device, a phase separation column is installed above the settling tank regenerator, connected to it via a filter element, which simultaneously supports the packing.

A schematic diagram of the device is shown in the drawing.

The preparatory device comprises a regenerator sump 1, which is installed directly above the phase separation a packed column 2, coupled to otstoyniKOivi through the filter 3. For oOespecheni neoohodimogo temperature on standing, and separation PROO otstoippk snaozhen steam ruoashkoy 4 and about teplooomennikom and column ooorudovana electrically b.

A condenser 7 is used to condense the gas mixture leaving the phase separation column.

The device is equipped with a conduit 8 for introducing the initial product into a settling tank-regenerator and nozzles 9 and 10, respectively, for taking the product for analysis and for withdrawing the vapor to the condenser. The liquid phase is withdrawn from the sump of the regenerator through the pipe 11.

In determining the quality of intermediate and final products obtained in the process of carbamide dewaxing of diesel

fuel, a multicomponent mixture in the form of a heterogeneous mass consisting of 25% of diesel fuel and 75% of the complex, comes from the process line through pipeline 8 to the sump-regenerator 1. The complex contains 5-10% of paraffins. In the sump reheater, the mixture is settled and heated with a steam jacket 4 and a heat exchanger 5.

The heated mixture under pressure passes the filter 3, is freed from mechanical impurities and enters the phase separation column 2, the packing of which rests on the filter. In the column, the liquid mixture is heated using an electric heater. The vapor is removed from the upper part for analysis through the pipe 9. Part of the vapor enters through the pipe 10 to the condenser 7, condenses and returns to the settling tank-regenerator. After

completion of the cycle and analysis of the sample; the liquid mixture is withdrawn from the sump of the regenerator through the discharge pipe 11.
