Recommend a sedimentation separation device
Thread Content
As the title suggests, if sedimentation treatment is required to remove solid impurities from tar, what are some suitable sedimentation and separation devices? Thank you!
It is recommended to use inclined plate or inclined tube sedimentation tanks, which offer high sedimentation efficiency, thorough solid-liquid separation, and do not suffer from clogging.
A sedimentation centrifuge can be tried
Horizontal screw centrifuge, hydrocyclone, or hydroseparator
Although the devices mentioned by the original poster all belong to the category of solid-liquid separation devices, their separation principle is not based on sedimentation.
In the treated light tar, the solid-phase impurities mainly consist of quinoline-insoluble substances (separated carbon, oligomeric carbon, inorganic substances). The proportion of these impurities in the mixture is very low, typically 3-5%. Light tar is primarily composed of aromatic rings, and its viscosity is similar to that of heavy residue. Could someone please provide a detailed explanation regarding the selection of sedimentation separation equipment, taking these factors into account? Thank you so much!
Do you want natural sedimentation or centrifugal sedimentation? Be more specific in your question
In the chemical production unit of coking plants, piston feed centrifuges are used to separate ammonium sulfate, while horizontal screw centrifuges are employed to separate sulfur paste. Due to the high viscosity of light tar, it is somewhat difficult to separate the solids contained in it. Therefore, it would be helpful if the person in question could provide information on parameters such as the density of the two phases, the viscosity of the tar, and the settling speed of the solid phase. Alternatively, samples can be analyzed to determine appropriate machine models and operating parameters. It is also possible to purchase a laboratory centrifuge for sedimentation tests at a cost of around 10,000 yuan
