Recently, the outlook for agricultural crops has improved due to innovative processing units that foster growth and quality in fertilizers, resulting in the need for effective management of air pollution from harmful emissions in the fertilizer industry.

The innovative scrubbing technology makes it possible to achieve the lowest ever dust emissions at a urea granulation plant in the US. The scrubbing system technology faces the challenge of stricter air pollution control of urea dust because of the development of new production in the USA and special attention on fine particulates, emission limits, and their influence on the human health.

Urea dust from fertilizer plants is considered to be a “particulate matter or PM”, an air pollutant that is regulated by the US EPA and has a notable health effect due to the infiltration of these tiny particles into the human lung. Consequently, the stipulation of under 10 mg of dust per Nm3 of gas in a dry state encourages the advancement of innovative scrubbing systems for air purification that enhance air quality.

The newly developed scrubbing system is considered to be a highly practical, the most efficient granulator and cooler air treatment device that meets new regulations. The unique scrubbing system consists of conditioning spray and downstream mesh pads. The new scrubber offers such an advantage as the horizontal orientation of the air treatment system resulting in easy access to internal components, which provide total system flexibility.

One more benefit is the capability to treat numerous gas contaminants in one common vessel. Also, it is possible to separate concentrations and/or chemistry due to the application of specific weirs that isolate individual sections of the air treatment device. Each stage can operate as an independent scrubber with its unique liquid-to-gas ratio.

After considering different air pollution control devices, it was decided that a wet scrubbing system is the best air treatment device to scrub the acids by circulating phosphoric acid. For example, venturi scrubbers and packed cyclone separators are used for these purposes, one of them being the challenge solution of the problem to handle phosphoric acid in a hot climate, and the clogging of the cyclone packing material by silicon compounds.

The venturi scrubbing system supports an ammonia absorption rate of 95 percent of 110 kilograms/hour lost from the reactor, while the dust emissions from fertilizer plants are about 20 kilograms/hour which makes this air treatment device perfect for the industry.

If you are looking for the best air treatment device to improve air quality, Redwood Technology offers a cutting-edge type of wet scrubber – a Multi-Vortex wet air scrubber.

Redwood technology is a fast-growing vendor of wet air scrubbers. The multi-vortex scrubber can remove gas emissions, dust, vapors, and other pollutants from a gas stream. It is an innovative technology created to save water that makes it more cost-efficient and differs from other types of scrubbers.  If you have any questions or would like to purchase a multi-vortex wet air scrubber, please contact us at info@rdwd.tech
