White Powdery Sodium Bicarbonate Chemical CAS 144-55-8 Soluble In Water

99%Min White Powder Sodium Bicarbonate Industrial Food Grade

Sodium bicarbonate, chemical formula: NaHCO₃, commonly known as baking soda, white fine crystals, white alkaline powder easily soluble in water, no change in dry air, slowly decomposed in humid air to release carbon dioxide. Sodium bicarbonate can be directly used as a raw material in the pharmaceutical industry for the treatment of
hyperacidity. It can also be used in film production, tanning, mineral processing, smelting, metal heat treatment, and in fiber and rubber industries. At the same time, it is used as a detergent for wool, as well as for agricultural seed soaking.

3.Feature Advantage

Sodium bicarbonate (baking soda, NaHCO3) can be used as an adsorbent for flue gas desulfurization. It can adsorb acid pollutants in flue gas by chemical adsorption, and at the same time, it can also adsorb some inorganic and organic substances by physical adsorption. In this process, the fine sodium bicarbonate powder is directly sprayed into the high temperature flue gas. At high temperature, sodium bicarbonate decomposes to produce sodium carbonate Na2CO3, H2O and CO2. The newly produced sodium carbonate Na2CO3 has corresponding reaction activity when it is generated and can react with acid pollutants in flue gas. Generally, the flue gas temperature is between 140 and 250 °C. Due to the activity of the sodium bicarbonate adsorbent, a slight excess of sodium bicarbonate (a stoichiometric factor between 1.1 and 1.3) is usually sufficient. In principle, sodium carbonate (soda, Na2CO3) can also be used for flue gas desulfurization. The reaction activity of sodium carbonate is slightly lower, but the process flow is almost unchanged.

Desulfurization effect of baking soda:

Sodium bicarbonate in different forms generally have good desulfurization effect, national standard GB1886.2-2015, especially with slurry and activated carbon adsorption saturated solution effect is better. From the kinetic process, the flow rate and temperature of the air flow have a certain impact on the desulfurization process of sodium bicarbonate. Industrial baking soda has a better effect when the air flow speed is not high and the temperature is lower than 150℃.
