Sodium silicate from rice husk / hull ash (RHA)
Today, rice is grown and harvested on
every continent except Antarctica. The majority of all rice is produced
in India, China, Japan, Indonesia, Thailand, Burma, and Bangladesh.
Asian farmers’ accounts for 92-percent of the world's total rice
production. More than 550 million tons of rice is produced annually
around the globe.
20% of paddy is husk / hull. 110
million ton of husk is produced per year worldwide. Most of it is used
as fuel. On relatively good combustion 80% of husk is consumed. Thus we
have 22 million ton rice husk ash (RHA) generated per year.
Rice husk / hull ash (RHA) contains
- Biogenic Amorphous Silica
- Carbon
- Un-burnt rice husk / hull
RHA generated in husk fired boiler
poses a solid waste disposal problem. The ash is presently used as land
fill.
Unlocking the value of Ash
Technology
The simple process involves treating the rice husk / hull ash (RHA)
with a solution of alkali at relatively low temperature and low
pressure. The silica reacts completely with the alkali solution forming
liquid commercial silicate with suspended particles of carbon. The
carbon is activated, dried & packed. The liquid commercial silicate
is further processed or sold.
