Coal tar is the raw material of chemical plants. The solid substances in coal tar can be removed as much as possible by the solid-liquid filtration separation method. BLU-HG-01 wedge wire filter element can greatly reduce the solid content in coal tar, and the filtered coal tar can meet the requirements of catalytic hydrogenation to produce gasoline and diesel.

Working principle of BLU-HG-01 wedge wire screen filter element: Under the action of pressure, the liquid and solid phases are forced to mix through the wedge wire screen filter element, and the solid particles are intercepted on the medium, so as to achieve the purpose of separating coal tar and solid particles.

Comparison Of Non-Desalted And Desalted Coal Tar Before And After Filtration By Wedge Wire Screen Filter Element

  • The density of coal tar without electric desalting is higher than that of coal tar with electric desalting. This shows that the electric desalting effect of coal tar is relatively good, and most ammonium salts and metal salts in coal tar have been removed.
  • The density of non-electric desalted coal tar and electric desalted coal tar changed before and after filtration, which shows that the filtration and separation of coal tar have produced a certain effect.
  • The change before and after filtration of nonelectric desalted coal tar is much smaller than that before and after filtration of electric desalted coal tar.
    This indicates that the filtration effect of coal tar is better and the content of solid matter after filtration is smaller after electric desalting.

Viscosity Comparison Of Non-Electric Desalted Coal Tar And Electric Desalted Coal Tar Before And After Filtration And Separation By Wedge Mesh Filter Element

  • The viscosity of both UN desalted and desalted coal tar changed before and after filtration. This shows that the filtration and separation of coal tar have achieved a certain effect.
  • The viscosity change of electrically desalted coal tar before and after filtration is greater than that of non electrically desalted coal tar. This shows that the filtration effect of coal tar after electric desalting is better than that without electric desalting.

Solid Content Of Un Desalted Coal Tar And Desalted Coal Tar Before And After Filtration And Separation By Wedge Wire Screen Filter Element

The effect of coal tar filtration and separation is mainly determined by the change of solid content before and after filtration.

  • The filtration efficiency of UN desalted coal tar is: η (toluene insoluble) ≡ 68.99% η (quinoline insoluble) = 71%. The filtration efficiency of electrically desalted coal tar is η (toluene insoluble = 88% η These data show that the filtration and separation effect of coal tar is ideal and can meet the requirements of industrial application of coal tar.
  • Whether it is η (toluene insoluble) or η (quinoline insoluble matter) and the filtration efficiency of coal tar that has been desalted by electricity is greater than that of coal tar that has not been desalted by electricity. This shows that the filtering effect of coal tar is better after electric desalting.

The optimum conditions for coal tar filtration and separation are as follows: the filtration temperature is 110C, the flow is 3L/min, and the filter element specification is 10 microns. The number of filter elements is 10.
