Conversion of rice hull ash into soluble sodium silicate

Conversion of rice hull ash into soluble sodium silicate

+

Sodium silicate is used as raw material for several purposes: silica gel production, preparation of catalysts, inks, load for medicines, concrete hardening accelerator, component of detergents and soaps, refractory constituent and deflocculant in clay slurries. In this work sodium silicate was produced by reacting rice hull ash (RHA)...

Industrial sand and gravel, often called "silica," "silica sand," and "quartz sand," includes sands and gravels with high silicon dioxide (SiO2) content. These sands are used in glassmaking; for foundry, abrasive, and hydraulic fracturing (frac) applications; and for many other industrial uses. The specifications for each use vary, but silica resources for most uses are

The solubility of silica is a function of pH and temperature. Lime softening and lime plus soda ash softening are most effective in removing silica. Other options are process related: (a) run the RO system at reduced recovery, (b) increase the feed water temperature – silica solubility increases with temperature, and (c) use silica inhibitors.
