Ammonia gas is a very common by-product of chemical processes. Chemical manufacturers are required to reduce their ammonia gas emissions because it is classified as a hazardous substance by the United States Emergency Planning and Community Right-to-Know Act (EPCRA). There are strict requirements in regards to its storage, production, and use. Rexarc International Inc. provides ammonia scrubber, which guarantees 99% ammonia removal efficiency. Thus, we help our chemical industry clients adhere to EPCRA regulations, and keep their ammonia emissions low.
The following facts about ammonia gas prove why it is a matter of concern for chemical industry manufacturers and EPCRA.
Ammonia is a pungent gas, which may cause discomfort in the form of burning sensation in eyes, throat, nose, respiratory tract. In severe cases, it can even cause lung damage, blindness, and death if this gas enters into the body through breathing, or swallowing.
The odor threshold for this gas is 5 ppm, which suggests potential danger.
The gas has an Immediately Dangerous to Life and Health (IDLH) concentration of 300 parts per million by volume (ppm).
The OSHA Permissible Exposure Limit (PEL) is 50 ppm.
The gas is moderately toxic with an explosion range of 16-25% in air.
Ammonia is corrosive, and can damage metals.
Due to its tendency to react with acid gas pollutants, the gas is considered as a precursor to PM10 and PM2.5 criteria air pollutants. It forms ammonium salts on reaction with acid present in the atmosphere. The most common byproducts are ammonium sulfate or ammonium nitrate.
Rexarc ammonia scrubbers are designed to remove ammonia gas that is generated from the calcium carbide during the acetylene production. This helps avoid the formation of ammines that when compressed, are known to clog flame arresters and cylinders. The scrubber is automatically filled and drained with water, which absorbs the ammonia. A drain is used to limit the level of water in the scrubber and to remove water that contains the ammonia. Pall rings are used to break the acetylene stream into small bubbles to remove the most ammonia possible.
Our ammonia scrubber is designed for long-term, and continuous operation. Its operational efficiency depends on these factors:
The temperature of the acetylene stream
Temperature of the water entering the scrubber
The presence of particulates, and chemicals in the exhaust stream
We provide ammonia scrubbers in the following specifications:
