Pollution Control in Fertilizer Production by C.A. Hodge

By C.A. Hodge

This timesaving consultant addresses approximately each point of toxins keep watch over for the mining, creation, transportation, and distribution of chemical fertilizers–covering present and rising applied sciences for all segments of the undefined, together with uncooked fabrics construction, finish items, and by-products. Introducing long term stable waste administration for either the phosphate and potash industries, pollutants regulate in Fertilizer construction. files the dealing with of potassium chloride at each point explores the main complicated suggestions for lowering noxious emissions within the surroundings studies the applied sciences had to renovate current or discontinued amenities analyzes tools for changing effluents and by-products to valuable items explains the environmental legislation and rules affecting the undefined, supplying confirmed techniques for compliance and extra!

There would be a financial incentive to recover the cadmium if its current high market price remains in force. Cadmium is thus definitely an undesirable element in fertilizers, although current fertilizer use presents no immediate danger. The development of a process for cadmium removal should be given high priority. References 1.

B Phosphate Rock Slurry: Pipelines A more recent trend in the industry is the use of slurry pipelines, which require lower installation and operating costs than that those of a transport belt, truck, or railroad system once distances exceed more than a few miles. They are environmentally superior to dry ore handling systems since they practically eliminate dust and particle emissions and reduce discharge of NOx, F, and CO2. Pipeline is generally made of carbon steel (API 5L Ã 52 or 5L Ã 56). It is usually located underground and has both protective coating and electronic protection.
