mixing diatomite countercurrent

mixing diatomite countercurrent - thesquarespoon

Ore is extracted by countercurrent decantation with a hydrocarbon solvent. Solvent is recovered from the extract by multiple effect evaporation followed by stripping. The spent diatomite is contacted with water and solvent is recovered from the resulting aqueous slurry of spent diatomite by steam stripping at superatmospheric pressure. Get P

Diatomite reservoir rocks are characterized by high porosity (35 - 70%), low permeability and have a favorable response to thermally enhanced recovery methods. Fracture reconsolidation or healing occurs, in some cases, during heating of diatomite. Silica dissolution is considered one of the main mechanisms that leads to fracture consolidation.
