Fertilizer
Super Phosphate production requires the
acidulation of phosphate rock with sulfuric acid to recover the phosphates. In most cases,
the rock also contains high levels of fluorine that combines with silica in the rock to
form silicon tetrafluoride. (SiF4). To minimize waste and chemical usage, the silicon
tetrafluoride is scrubbed to produce fluorosilicic acid that is then returned to the
acidulation process. Although very soluble, the byproducts of this process also include
silica oxides that are not soluble. Ceilcote APC has significant experience in the design
and supply of multi-stage eductor
venturi systems to meet recovery, operational and regulatory requirements. For
nitrogen based fertilizer production, our line of fluid-bed scrubbers or venturi/packed scrubber
combinations can provide both fine particulate control and ammonia odor reduction while
minimizing chemical make-up and effluent requirements. Other applications for Ceilcote
scrubbers include controlling H2S emissions, odors, and particulate from waste to
fertilizer recycling processes.
