Sodium Bicarbonate
Sodium bicarbonate is used for acid gas control, soil remediation, slurry walls, and drilling. Sodium Bicarbonate has been used for air pollution control since the 1960’s when the electric power industry discovered that it is effective for acid gas control when directly injected as a dry sorbent. Today it is used to control gases from a variety of combustion processes, such as:
- Waste Incineration
- Foundries
- Aluminum Smelting
- Ethanol Production
- Brick Manufacture
- Co-Gen Facilities
Sodium Bicarbonate is thermally activated, which expands the crystal’s surface area, exposing far more reaction sites for acid neutralization than comparable sorbent particles. This is the key to its efficiency advantage. Church & Dwight Bicarbonate is available in ready-to-inject particle sizes or can be milled at your site for even higher performance. In addition, sodium bicarbonate is offered in bags, bulk sacks, bulk pneumatic trucks, or railcars.
In geotechnical applications, sodium bicarbonate is an effective buffer that keeps drilling fluids and other bentonite slurries in the proper pH range.
Sodium Bicarbonate can also be used as a mild abrasive to remove paint, corrosion, and surface contamination from softer, less resilient surfaces.
Carpenter Brothers, Inc. sells Natronx (formerly Church & Dwight) sodium bicarbonate products for acid gas control. While Natronx is best known for its Arm and Hammer brand, its sodium bicarbonate products have been used for air pollution control since the 1960’s when the electric power industry discovered that they could directly inject it as a dry sorbent for acid gas. Sometimes referred to as Sodium Bicarbonate Dry Injection Technology (SBDIT), it has been further developed to control sulfur dioxide, hydrogen chloride, sulfur trioxide, and hydrogen fluoride emissions. Natronx is probably best known for its familiar Arm and Hammer orange box of bicarbonate that most people have in their refrigerators. However, its industrial sodium bicarbonate products are used in many industrial applications.
