This paper intended how to recover useful urea dust to control air pollution and that of saving energy. Lot of urea dust is emitted during product handling like falling from one conveyor to another, screening, de-lumping, bagging, etc. To recover the dust, wet de-dusting systems are installed. In the dust recovery system urea particles suspended in the air stream are dissolved into water. Dust controls an example of sustainability. National Fertilizers Ltd always look at ways of saving the environment, by optimizing their basic processes, raw material utilization, saving water etc. As a socially responsible company, one such illustrative example is the dust control project in urea conveyors system. Fugitive dust is an ongoing issue faced by most conveyor operators working with fine or powdered material. With raised awareness spurred by tighter regulatory standards, effective dust management has become an increasingly important challenge, motivating operators to employ efficient, cost-effective methods of particle management. Urea dust produces in handling of urea by conveying system with hopper assembly & bunkering. Urea dust at the conveyors hopper is mainly due to impact and attrition. Fertilizer dust emission is an increasingly serious problem creating a growing concern about atmospheric pollution and its possible ecological and toxicological effects. Contact with urea dust is a recognized health hazard. The handling and storage of urea requires special attention to several product related properties and external factors. Dust particles produced depends upon process condition, e.g. temperature, weather condition and equipment used for conveying system. External factors including climatic humidity and how urea is stored and for how long also play a big part. Dust is an ongoing issue faced by most conveyor operators working with fine or powdered material. In addition to providing a safe clean workplace, choosing the equipment best suited to managing urea’s hygroscopic qualities will save time and money. Together, these factors can have a significant impact on the cost of operation. Because of the varying types and diversity of dust control methods, powder and fine material handlers should consider evaluating causes, problem areas, dustgenerating processes and potential cargo management techniques to arrive at the optimum approach for their operation.
